viper wire rope lubricator price free sample

The manual lubrication of wire ropes via the drip, brush, spatula or rubber glove method has always been a difficult maintenance task. Typically employed are messy asphaltic or “blackjack” type products, which have coating abilities but very little lubrication or penetration properties.

The VIPER Mid MK II Wire Rope Lubricator provides fast and effective lubrication of wire ropes from 5/16 in (8mm) to 2–5/8 in (67mm) in diameter, at speeds up to 6,670 ft (2,000 m) per hour. It eliminates the slow and labor-intensive task of manual lubrication, at the same time achieving more thorough results by forcing quality lubricant under high pressure right through to the core of the wire rope.

The system consists of the lubricator Collar assembly, which houses the polyurethane seals to suit the specific size rope. The assembly is clamped around the rope and anchored to a fixed point. The rope is then pulled through the collar as the lubricant is applied with a high pressure grease pump, forcing lubricant between the strands to the center or the rope. The result is a fully lubricated wire rope with a smooth minimal film of lubricant on the outer strands.

The benefits over conventional drip and brush or spray systems are substantial. The Viper MK II Wire Rope Lubricator operates at a higher pressure than most other lubricator collars on the market; this combined with the robust construction guarantees fast, safe and effective wire rope lubrication.

For lubricating larger rope sizes 2 in (50mm) to 6 1/2 in (165mm), you will need the Viper Maxi MK II. Viper Mini MK II lubricates rope sizes 15/64 in (6mm) to 1 13/32 in (36mm.)Please contact us for more information about these solutions.

"Despite its smaller size, the Viper Mini MK II has the same capability, strength and speed as the Viper MK II," Geoff Manley, general manager of Lubrication Engineers said.

Like its larger predecessors, this product eliminates the need for manual greasing with its single pass wire rope lubrication, at speeds of up to 1,000m an hour.

The added benefit of the Viper Mini is its smaller size, weight and portability, meaning that it can be carried and installed by one person, instead of two, providing superior protection for smaller steel ropes.

Lubrication Engineers predicts that these features will be particularly attractive to ship owners, who wish to protect the asset life of all of their steel ropes, which will likely vary in size.

"The Viper Mini really handles smaller ropes like no other lubricator. Ships may have 6 ropes, with varying diameters. The Viper Mini ensures that all ropes, of varying diameters, from 8mm to 30mm (35mm with HS Kit), receive effective lubrication, in a safe, mess-free application," Mr Manley explained.

Further, Lubrication Engineers is confident that the size and portability of the Viper Mini will make rope lubrication attractive to a broader market.

"Because the Viper Mini can be installed by one person instead of two, it means that rope lubrication is now available to smaller companies who may only have one maintenance staff member. Currently these companies are protecting their rope assets with manual greasing, or not at all.

"We know manual greasing can be dangerous to staff and it does not result in maximum asset protection, but until now many companies have not had the resources to implement effective rope lubrication. The Viper Mini changes that.

Fast and efficient rope lubrication: set up and install only take minutes. No tools required, clean and lubricate ropes in one application at speeds of up to 1,000mt/hour

Maximum rope protection: unique seal design induces lubricant penetration into rope for added corrosion protection. Direct increase in rope asset life

Document Handling - HGF (Newcastle), 1 City Walk, LEEDS, LS11 9DX, United Kingdom (54) Title ofthe Invention: Wire Rope lubricant Abstract Title: Wire rope lubricant (57) A wire rope lubricant having a base fluid as a majority component, and a wax or polymer as a minority component wherein at least one of the base fluid and the wax, or polymer, is biodegradable. A method of forming a wire rope having a plurality of wire strands, includes the step of applying the wire rope lubricant between the wire strands. The wax may be plant-based and is especially carnauba wax. The wax or polymer may have a melting point of 70-100 degrees C.

The present invention relates to a wire rope lubricant being at least partly, optionally substantially, biodegradable, and a wire rope including such a lubricant.

Wire ropes are well known for both onshore and offshore use, in particular in maritime situations. They can be used in all types of marine vessels, including ships, large boats, drilling units etc, and wire ropes are often selected for their flexibility, strength, resistance to deformation, and bending.

Wire ropes are generally formed of a number of heavy duty wires first forming strands, and then twisting of a number of the strands together, optionally around or over a core, to form a final wire rope.

Wire ropes are frequently subject to significant wear and tear, and often some corrosion, especially in maritime situations. It is naturally desired to maintain the highest properties for the wire rope, and to avoid or minimise any damage thereto. Thus, the use of wire rope lubricants to benefit the wire rope in use is well known in the art.

Some wire rope lubricants are used during the stranding and closure operation of wire rope manufacture, particularly to achieve integration within or around the strands prior to the subsequent twisting. Some wire rope lubricants are alternatively or additionally regularly applied to wire ropes in use to provide or continue any antiwear or anti-corrosion properties.

Conventional wire rope lubricants comprise a mineral base oil and thickener system, with one or more additives, typically at least an anti-corrosion additive. However, increasing environmental legislation around the world, such as the requirement to obtain a Vessel General Permit to allow a vessel into the waters of the United States of America (based on permissible discharges incidental to the normal operation of a vessel), make the use of conventional wire rope lubricants a challenge.

Thus, according to one aspect of the present invention, there is a provided a wire rope lubricant comprising a majority base fluid component and a minority of a wax or polymer component, wherein at least one ofthe base fluid and the wax or polymer is biodegradable.

In this way, the wire rope lubricant can be defined as an ‘Environmentally Acceptable Lubricant’ (EAL) as currently defined in Appendix A of the USA EPA 2013 Vessel General Permit (VGP) regulation used to define lubricants in the art. In meeting these regulations the product will be classed as biodegradable, minimally toxic and non bio-accumulative.

Optionally, the viscosity of the base fluid and the viscosity of the melted wax or polymer is the same (within a small range), or wholly or substantially similar, such that the viscosity of the wire rope lubricant including these components is predictable, and the viscosity properties of the components wholly or substantially act in a similar manner during any heating and cooling. This is especially where the wax or polymer is a solid at ambient temperature, and a liquid during any ‘hot application’.

A synthetic wax intended to have the same properties of Carnauba wax, or similar or substantially similar properties, is included within the scope of the present application, having in particular wholly or substantially the same viscosity and melting point range.

In the wire rope lubricant of the present invention, the base fluid component may comprise at least 70, 75, 80, 85 wt% of the lubricant, preferably in the range 88-91 wt%.

In the wire rope lubricant of the present invention the remainder can be quantum satis (q.s..), i.e. sufficient to make up 100 wt%, typically being an anti-corrosive additive up to 5 wt%, an anti-wear additive up to 5 wt% and an anti-oxidant additive up to 2-3 wt%, with an overall percentage generally being up to 13 wt%, typically a maximum of 5-6 wt%.

Wire rope lubricants can be used both onshore and offshore, and the present invention includes the lubricant being utilised in both applications. Wire rope lubricants are most commonly used on-board vessels or other offshore and maritime situations or locations for maintenance of the wire ropes.

Wire rope lubricants for in-service use are expected to have a good or high penetration rate into the wire rope, and provide corrosion protection and anti-wear properties. Optionally, wire rope lubricants have or form some adhesive properties and some also form a film around the wire rope.

Some wire rope lubricants are also delineated between ‘heavy bodied lubricants’ best suited for applications where the wire rope is exposed to an extreme or an abusive environment, and light-bodied lubricants having a lighter consistency to achieve better penetration of the lubricant into the interior of the wire rope. The wire rope lubricants of the present invention can be adapted for any suitable consistency based on the viscosity of base lubricant and level of wax or polymer thickener

Wire rope lubricants can be applied to an existing wire rope using any one of a number of known techniques, including spraying, dipping, painting, pneumatic or swabbing. Application is possible via automatic lubrication pneumatic ‘units’ through which a wire rope can pass, (available from Viper, Masto and CoreLube).

Wire rope lubricants can also be used during manufacture of a wire rope, in particular by application to one or more of the strands of the wire rope by one or more of the above techniques, or by ‘hot application’, prior to twisting of the strands to form the final wire rope. The applied wire rope lubricant is intended to form a layer or barrier, preferably a film, optionally also as a final outer surface of the wire rope once formed, to help protect the wire rope from corrosion.

Thus, according to a second aspect of the present invention, there is provided a method of forming a wire rope having a plurality of wire strands, comprising the step of applying a wire rope lubricant as defined herein between the wire strands, typically prior to twisting of the wire strands to form the wire rope.

Thus, according to another aspect of the present invention, there is provided a wire rope having a plurality of wire strands and including a wire rope lubricant as defined herein.

Typically, applied wire rope lubricant becomes depleted or contaminated over a period of time, and one or more new or further applications of the wire rope lubricant can be made to a wire rope, typically whilst the wire rope remains in use or in situ.

According to a further aspect of the present invention, there is provided the use of a wire rope lubricant as defined herein, wherein the lubricant is applied to a wire rope.

Manufactures and distributes a comprehensive line of high-performance lubricants that far exceed conventional lubricants in a variety of industrial and automotive applications. By significantly reducing downtime and maintenance costs, LE lubricants are also cost-effective, returning the initial price of the lubricant many times over.

Duolec® dual-acting additive imparts synergistic properties to lubricants, providing both wear-reducing and extreme pressure protection. It increases film strength and is temperature-activated to provide a protective layer.

The performance advantages offered by synthetic oils and synthetic greases vary by product, but they include improved thermal stability, improved oxidation resistance, a high viscosity index, improved lowtemperature properties, lower evaporation losses, reduced flammability and a lower tendency to form residues.

Proper lubrication of your wire rope, chain and cable can safely extend its operational life regardless of application. Cranes, elevators, shovels, drilling rigs, suspension bridges and draglines are some of the many applications that use wire rope, chain or cable to perform work such as pulling, dragging or hoisting. These applications often are exposed to harsh environmental conditions, including extreme weather. Lubrication Engineers can help your wire rope, chain and cable last longer and operate safely by implementing a lubricant reliability program and recommending the right lubricants for the job.

Most factories and manufacturing facilities use compressed air systems for a variety of applications, and keeping these air compressors running is critical to keeping the entire operation running. Nearly all air compressors require a form of lubricant to cool, seal or lubricate internal components. Proper lubrication will ensure that your equipment will continue operating, and the plant will avoid costly downtime and repairs. Proper lubrication also will help air compressors run cooler and consume less electrical energy. It is simple: reduced friction = reduced heat = reduced energy consumption. Compressed air systems in most manufacturing plants consume a majority of the daily power requirements, so if you are looking for a continuous improvement project, reducing energy costs through better lubricant practices is a sure winner.

Process ovens in food processing plants and other manufacturing facilities are vital to production output, but keeping them properly lubricated can be difficult. Extreme temperatures, continuous operation and – in some cases – dirty operating conditions are typical challenges. Offering several high-performance lubricant formulations, Lubrication Engineers has helped companies worldwide with their process oven lubrication needs. If you are interested in creating more uptime for your operation, let LE’s experienced and certified consultants help you overcome the challenges of oven chain lubrication.

15 Viper MKII Technology Key Components Viper Rope Cleaner Viper Rope Cleaners enable the removal of contamination or built-up old lubricant from the wire rope prior to lubrication, thus improving the effectiveness of the lubrication process. The Rope Cleaners provides more thorough cleaning of ropes than the Scraper Plates as it is designed to follow closely to the contours of the wire rope strands. There are 2 types of Viper Rope Cleaners Viper Groove Rope Cleaner: Viper Smooth Bore Rope Cleaner: closely shaped to the wire rope strands (i.e. no. of strands, lay direction) to thoroughly clean debris, even those stuck within wire groove valleys used on ropes where groove valleys are minimal (e.g. multistrand, non-rotational ropes, ROV cables, etc) Viper Scraper Plates Aluminum Scraper Plates are fixed to the ends of Mid-Viper MKII and MAXI-Viper MKII units. It serves to scrap off surface contaminants on wire rope prior fresh lubrication and also protect the seals from potential damage of protruding broken strands by flattening loose wires.

Wire ropes, sometimes referred to as cables in gauges less than 3/8 in. dia., are connective elements used in static and dynamic work environments servicing industry and infrastructure needs. Common static wire-rope applications can be found in the main support systems for suspension bridges or as tensioned cable used to support tall, free-standing structures such as microwave cell towers. Popular dynamic applications include mining-cage hoists, elevator hoists, draglines, and cranes in which the wire rope moves under tension and load to lift, hoist, and transfer motion and power.

Originally developed in early 19th century Germany for the mining industry as a better alternative to existing metal chains and hemp rope—regular failure always proved catastrophic—wire rope is still manufactured in a similar manner from multiple strands of metal wire laid (wound) in a helical pattern around a center core. The center core can be made from hemp rope, plastic, fiber, or steel (specific to aircraft cable).

The multi-strand fabrication method provides tremendous tensile strength (100,000 to 350,000 psi, depending on the grade of wire steel) for lifting and hoisting while delivering flexibility of movement needed for traction and movement recovery over pulley or drum surfaces. In addition, stranded wire provides superior resistance to crushing and abrasion that can result from the extreme working conditions in which wire rope is often employed.

Wire ropes are gauged (sized) based on the number of strands surrounding the core and the number of wires used per strand. For example, an 8×19 wire rope will consist of 8 strands laid around the core, with each strand consisting of 19 wires. With 152 individual wires rubbing against each other as the rope moves over the drum or sheave pulley, friction and wear will result. That must be combatted with an effective lubrication strategy designed to maximize reliability and optimize life cycle.

In addition to load and movement, wire ropes are often subjected to weather and operating conditions that can introduce contamination and place heavy demands on the rope lubricant. Lack of a lubrication strategy can exasperate the situation and cause the wire rope to fail prematurely.

Dynamically loaded wire ropes typically fail from fatigue, wear, corrosion, and/or core shrinkage. Fatigue is a result of repetitive work cycles, subjecting the rope to constant bending, torsional twisting, and tension. These stresses eventually lead to broken wires within the strands. These same cyclic stresses also lead to high contact pressures between the wires that, in turn, set up a friction-and-wear cycle when the rope is inadequately lubricated. In addition, poorly lubricated ropes will allow solid contaminants between the wires as they open and close around the pulley. This contamination then sets up as three-body abrasion, causing accelerated wear inside the rope.

Because wire ropes are made from steel and can be subjected to outside elements such as moisture and acidic chemicals, unless a galvanized-steel rope is employed, successful corrosion abatement will rely solely on a quality lubrication program.

Core shrinkage starts to occur when the initial lubricant charge dries out, resulting in a reduced diameter and loss of support for the surrounding strands. This, in turn, can cause the strands to overlap one another, leading to nicked and cut wires.

Wire-rope lubricant is automatically applied by using a pressure boot clamped on the rope in a tensioned straight section. Lubricant is gently pressured into the wire rope as it passes through the boot. Photo courtesy Lubrication Engineers Inc., Wichita, KS; lelubricants.com

New wire ropes are lubricated at the factory. The lubrication gradually depletes, once the rope is placed in service, at a rate that depends on the load and working conditions. When setting up a wire-rope lubrication program, the first rule of thumb is to ensure the field lubricant is compatible with the original lubricant charge.

Considering the four common failure modes, a good lubricant must be able to coat the outside of the wire rope and get in between the wires to provide a lubricant film between all of the moving wires. The lubricant also must provide adequate corrosion protection. Because most wire ropes fail from the inside, it is important to always use a penetrating lubricant first. Penetrating oils are petroleum-based and contain solvents that allow these lubricants to “creep” into the core and ensure the strands and core are fully coated with a heavy lubricating film. Once in place, the solvent eventually evaporates, leaving only the oil film.

In extreme operating environments, the wire rope may also require a coating oil to protect the outside surface, sealing out moisture and protecting the inner strands and core. This coating oil also protects the outer rope surface from wear and damage.

The correct choice of lubricant is based on the application, load, rope construction, and working environment, all of which will require expert assistance from your local lubricant supplier.

If a new lubricant is to perform correctly, a full wire-rope cleaning must take place prior to re-lubrication. Ropes tend to pick up dirt in service and old lubricants can harden on the rope exterior. Cleaning ranges from a wire-brush-and-solvent cleaning, if only light surface debris is present, to a full steam clean for heavily soiled wire ropes.

Wire-rope lubricant can be applied manually or automatically in the field. Most manual applications are performed with a brush, spray, or even a dip-tank process, depending on the length and size of wire rope. If the lubricant is to be manually applied, always strive to do so at a directional change point, such as a pulley sheave or drum, when the rope strands naturally open up to accommodate flexibility.

For automatic application, a device known as a pressure boot is used. It is clamped on a tensioned straight section of the rope and lubricant gently pressured into the wires as the rope passes through the boot.

Guy lines are wire ropes used to secure large transmission towers, and their structural integrity is paramount to the operability of Sentech’s transmission infrastructure.

He adds that, for wire ropes to be lubricated, the lubricant needs to reach the core of the various strands in wire ropes, thereby ensuring 100% coverage. Common practice in the industry is to apply a thick and tacky lubricant manually to the wire ropes.

However, this method significantly reduces the lubricant’s ability to protect the wire ropes from corrosion, as the lubricant does not reach the core of the wire rope, functioning only as an outer cover. This, says FitzGerald, “leaves moisture trapped inside the wire rope, which causes corrosion to form from the inside out”, with dirt also prone to adhere to these tacky lubricants.

This type of internal corrosion is difficult to monitor and identify because it is covered mostly by the thick layer of lubricant, and evidence thereof will show only once critical levels of corrosion have taken place, at which point a complete replacement of the wire rope will be required, as its structural integrity has been compromised.

Filter Focus employs an automatic wire rope lubricating device, the Viper wire rope lubricator, which is manufactured by Holland-based company Viper Wire Rope Lubricator.

The Viper is a collar that attaches to wire ropes and is fed with lubricant through a pneumatically powered lubricant pump. The lubricant is pumped from a pail, through hydraulic hoses and then into the Viper collar, where it is forced into the wire rope at about 5 000 psi. This forced application ensures that the lubricant reaches the core of the wire rope. Any excess lubricant is directed to an overflow outlet, from where it is returned to the lubricant pail.

Using high pressure also results in any moisture within the wire rope being forced out through the front end of the Viper before the new lubricant is applied.

The font end employs two mechanical wire-rope cleaning devices – a polyurethane scraper plate and a metallic groove cleaner. The scraper plate removes most of the excess lubricant, while the groove cleaner removes embedded lubricant from the grooves of the wire rope.

For the purpose of using the Viper on static wire ropes, Filter Focus has a hanging trolley to catch the removed old lubricant so that it does not contaminate the working area, other products, equipment or the surrounding environment.

This entire process is automated and, in the case of moving wire ropes, it simply requires an operator to engage the motor of the wire rope drum to coil and uncoil the wire rope, while another operator monitors the Viper and engages the lubricant pump.

FitzGerald says wire ropes vary in size from 8 mm to 63 mm, all of which can be accommodated by the Viper, as it uses polyurethane sleeves that can be inserted into the Viper collar according to the specific size of the wire rope, as well as the lay of the rope. Local Adaptations

Sentech approached Filter Focus in early 2015 with the request to improve its wire rope lubrication operations. Subsequent planning has been taking place over the past five months.

FitzGerald notes that Filter Focus had to make a few adaptations to the setup and operation of the Viper to meet Sentech’s specifications, chiefly because the wire ropes used by Sentech are static.

Sentech’s wire rope lubrication operations were previously conducted by having a person suspended in a bogey, or bosun’s chair, from the wire ropes. The person had to manually apply a thick lubricant by hand, while winches were used to hoist and lower the bogey.

“We can now strip and relubricate a single wire rope in about 30 minutes,” says FitzGerald, adding that user safety has also vastly improved because two people can operate the Viper from the ground, with one operating the winches and the other guiding the lubrication cradle.

Further, because the Viper was designed for use on moving wire ropes, Filter Focus had to design its own lubrication cradle to accompany the Viper up and down static wire ropes. This cradle is installed behind the Viper and carries a pail of lubricant and a pneumatic pump to pressurise the Viper collar.

For standard wire rope cleaning applications, FitzGerald says, the Viper can extend periods between lubrication intervals to about eight or nine months, whereas previous methods required lubrication intervals of about three months. However, in the case of Sentech, the previous lubrication periods of two years will be extended to five years where the Viper is used.
