Wire ropes can be seen everywhere around us, they are made of strands or bundles of individual wires constructed around an independent core, suitable for construction, industrial, fitness, commercial, architectural, agricultural, and marine rigging applications.

Wire rod is made from high carbon steel wires(0.35 to 0.85 percent carbon) in a hot rolling process of a required diameter, usually from 5.5mm to 8 mm.

Wire rod is drawn to the required diameter by the 1st drawing machine after descaling dust and rust, adding mechanical properties suitable for application.

Positioning the wires different or the same size lay in multiple layers and same direction, or cross lay and diameter is maintained by one-third of the rope size.

So in theory, it is very simple to manufacture wire ropes. However there are many more details that must be closely monitored and controlled, and this requires time and experienced personnel since it is a super complicated project you cannot imagine.

CLEVELAND, OH – Mazzella Lifting Technologies, a Mazzella Company, is pleased to announce the acquisition of Denver Wire Rope & Supply. This acquisition will strengthen Mazzella’s footprint west of the Mississippi River and reinforce Mazzella’s commitment to be a one-stop resource for lifting and rigging services and solutions.

Denver Wire Rope & Supply has been in business since 1983 and services a variety of industries out of their location in Denver, CO. Denver Wire Rope & Supply is a leading supplier of rigging products, crane and hoist service, below-the-hook lifting devices, and certified rigging inspection and training. Effective immediately, Denver Wire Rope & Supply will operate as Mazzella / Denver Wire Rope. Terms of the transaction are not being disclosed.

“Denver Wire Rope & Supply will complement the wide range of products and services that Mazzella Companies offers. We are dedicated to being a single-source provider for rigging products, overhead cranes, rigging inspections, and rigging training. Both companies commit to a customer-first mentality, providing the highest-quality products, and leading by example when it comes to safety and sharing our expertise with customers and the market,” says Tony Mazzella, CEO of Mazzella Companies.

This acquisition will provide Mazzella Lifting Technologies with a western U.S. location that will allow them to grow and expand their reach past the Oklahoma City market.

“Our team and family are excited to be part of the Mazzella Companies. This acquisition strengthens our place in the market and allows our team to continue to provide excellent service and products to our valued customer base and expand our offering,” says Ken Gubanich, President of Denver Wire Rope & Supply.

“Over the years, we have had numerous companies show interest in purchasing Denver Wire Rope & Supply, none seemed to be the right fit. We are looking forward to becoming a part of an aggressive, passionate, and progressive organization. As a family business for over 36 years, it is important to us that our customers/friends, suppliers, and team members continue to be treated with first-class service, products, and employment opportunities.

“We wish Ed and Carol Gubanich all the best in their retirement. We welcome Ken and the other second and third-generation Gubanich family members, as well as the entire Denver Wire Rope Team, into the Mazzella organization,” says Mazzella.

We’ve changed our name from Denver Wire Rope to Mazzella. Aside from the new name and logo, our member experience is virtually unchanged. Here are some common questions and answers related to this change.

In 2019, Denver Wire Rope & Supply was acquired by Mazzella Companies to expand lifting and rigging products and services to the western half of the United States.

In 1954, James Mazzella founded Mazzella Wire Rope & Sling Co. in Cleveland, OH. For over 65 years, the company has grown organically by nurturing historic relationships, expanding its product offerings, and entering new markets through acquisition.

Today, Mazzella Companies is one of the largest privately held companies in the lifting and rigging industries. Since our humble beginnings, we’ve grown to over 800 employees with over 30 locations across North America. Our product offerings have expanded from basic rigging products, to include:Overhead crane fabrication

One thing that hasn’t changed is our commitment to a no-excuses, customer-first mentality that extends from the shop floor to the front office. Some of the major markets Mazzella serves are: Mining, Steel, Oil & Gas, Construction, Energy, Shipbuilding, Vehicle and Durable Goods. Mazzella’s diverse portfolio includes Sheffield Metals a manufacturer and distributor of coated bare metal products for engineered metal roof and wall systems. New Tech Machinery is a manufacturer of portable roof panel and gutter machines—recognized as the world’s finest portable rollformers.

Just the name. We want to be clear that our people, locations, products, and services have not changed. We will be moving to the Mazzella name for all rigging brands under the Mazzella Companies umbrella in order to create a better experience for our customers and employees.

With all the Mazzella rigging locations working as one team and under one name, your level of service and support will be improved exponentially. Nothing will change in terms of the local team you’re used to working with. The same people will still be here—the only thing that will be changing will be the name of the organization they work for. You now have more resources, inventory, and clearer lines of communication. Our goal is to improve your experience and instill confidence and comfort in every interaction.

Mazzella is experiencing rapid growth. With this growth, we can better serve our customers as one team under the Mazzella name, versus many companies operating independently. The only change you will experience will be better service and improved lines of communication between our people and yours.

For sure! We hope to expand our service line across the entire United States. With over 30 locations, your level of service should only be improved and lines of communication more clear.

Manufactured in Calgary this cable is made by coating offshore aircraft cable with a tough and durable PVC coating. The colour is flat black to best fade into the background.

smaller sized cables, we find using an oversized thimble often makes the attachment of fittings easier. Below is a 1/8” standard, a 3/16 AN Zn, and a 1/8” AN Zn Thimble.

AN thimbles come in either cold-rolled steel (zinc plated) or stainless steel (natural finish). Fit cable diameters from 1/16” to 3/8” to meet the most demanding marine, aircraft or industrial requirements. AN Thimbles meet all Military Specifications.

Often generically referred to as Crosby clips and occasionally as bulldogs we offer both forged and malleable wire rope clips. Forged clips are required for use in overhead lifting. The malleable clips are recommended for non critical light duty applications such as guard rails, guy wires etc. The efficiency rating on the proper number of properly applied wire rope clips is 80% of the strength of the wire rope. We offer both offshore and Genuine Crosbie Wire Rope Clips. Fist Grips have a couple of advantages over Wire Rope clips in that they are impossible to apply incorrectly and they damage the rope less in situations where the clip will be removed.

Wire rope clips must be re tightened after applying load. In accordance with good rigging practice wire rope and its terminations should be regularly inspected.

Different Brand or trademark names for similar but very different products. When looking at a lifting sling from an aluminum tube’s point of view, it prefers supple, soft and nonabrasive slings. A round sling is the prefect choice rather than a steel sling. Round slings are made of many strands of polyester covered with a protective polyester sheath.

Unfortunately, polyester melts at approx. 250°C (~480°F). Research has shown that a 2k luminair-housing can reach temperatures of about 190°C (~370°F), with the truss-chord straight over it being almost 140°C (~280°F). Accidents have been reported of round slings being melted by spots, pyro or the heat of the rays, and as a result, trusses have fallen. When round slings are used, a safety backup must be applied such as a wire rope or chain sling.

So rather than have a backup steel sling why not make the sling out of steel but softer than a single cable. A steel round sling has a normal outside webbing for soft slings, but instead of the polyamide core, the steel round sling has a core made of many small steel cables, which makes it resistant to high temperatures. The steel wires within the steel round are as flexible as a normal soft sling, but have a much better fire resistance. The steel round can be used in circumstances where the normal soft slings are not allowed.

The outside webbing is black, including an identification label and a hidden inspection window to inspect the steel wires within the sling. The wire-rope core has better heat resistance than the truss itself.

Down Stage Right can supply most of your rope and cordage requirements from twill tape and black cotton tie line to large diameter manila and polyester ropes and braids. To make life very very confusing the synthetic fibre ropes are all available in either a 3 strand, solid braid, double braid or parallel core configuration in nylon, polyester or more exotic materials. Polyester ropes are available in a spun or non spun finish. Due to the huge number of different sizes, colours, materials and braid types combinations (and to simplify things) Down Stage Right Industries stocks several favourites that we have found the theatrical industry usually purchases. If you need a particular rope we are happy to bring in the particular configuration and colour that you want. Please call for details or recommendations for a particular product.

Twill tape is a flat twill-woven ribbon of cotton, linen, polyester, or wool. Used in attaching soft goods and electrical cables to pipes we offer both cotton and polyester twill in 100 yard rolls.

Used as a general purpose tie line for drops or cables it is offered in 1000 and 3000" spools. Available in cotton and polyester. Size 4, #4.5 or 1/8” and #5.

The primary advantage of sash cords are their handling characteristics and their knot holding ability. It does not have the strength or durability of double braids. Available in white as a cotton polyester blend or in black as spun polyester. Sash braid is generally a coarser cousin of solid braid.

Often mislabeled as hemp, manila is significantly stronger and is used in for hand lines in counterweight rigging and as general purpose spot line rope. We only carry #1 grade sea worthy manila. Manila has generally been replaced by synthetics in our industry

Working loads are guidelines only. Once put into service rope is continually deteriorating. Manila rope will deteriorate in storage even under ideal conditions.

Solid braid ropes are sometimes referred to as “sash cord” because this pattern was used to raise sash windows. It is formed by braiding 8 to 18 strands in a reasonably complicated pattern with all the strands rotating in the same direction on the braider. The individual stitches are oriented in the same direction as the rope. The center may contain a filler core. These ropes maintain their round shape well and therefore work exceptionally well in pulleys and sheaves. They tend to have high elongation and are generally less strong than other forms of construction, and are difficult to splice.

"Double braid" ropes, also referred to as "Marine Ropes" or "Yacht Braid" or “2 in 1” are perhaps the most well known braided rope on the market today. They are constructed of a hollow braided rope, which acts as a core inside another braided rope. The combination of the 2 ropes in 1 results in a rope with higher tensile strength than commonly found in twisted ropes. The inner rope and outer rope are generally designed to share the load fairly evenly. Double braid ropes have a torque free construction, and are easily spliced. However, caution must be exercised where double braid ropes are run over pulleys, through hardware or in any situation where the outer rope may slide along on the inner rope and bunch up. This condition, often called "milking", will cause dramatic loss of strength by causing the entire load to go onto the inner rope, because the sheath is bunched up and therefore not under the same tension as the inner rope. Polyester double braid ropes big advantage is that they do not have the same stretch as nylon. They can also be made with a soft “spun” covering giving a better hand feel. The elasticity of nylon ropes can absorb sudden shock loads that would break other ropes.

Manufactured by New England Ropes Stage Set X is a superior replacement for manila with a longer life, much higher strength and no slivers. This rope was specially developed as a replacement for manila hand lines in counterweight rigging and we find it to be Cadillac of the synthetic hand line ropes. Multiline II is a three stranded rope with the same ideals in mind. It is more economically priced and has slightly different handling characteristics.

PRODUCT DESCRIPTION: New England Ropes" Stage-Set X is the softest, strongest and most environmentally stable product available in the theatre industry for counterweight systems. It"s parallel core of polyester fibre contained within a helically wrapped polyester tape and covered by a braided polyester jacket, remains firm and round under all load conditions and resists crushing in rope locks.

Compliance to the above specifications is based upon testing according to the Cordage Institute Standard Testing Methods for Fiber Rope and/or ASTM D-4268 Standard Methods of Testing Fiber Ropes.

Tensile strengths - Are approximate average for new, unused ropes. To estimate the minimum tensile strength of a new rope, reduce the approximate average by 15% (Cordage Institute defines minimum tensile strength as two standard deviations below the average tensile strength of the rope).

Good resistance to most minerals / organics, acids, weak alkalis, bleaches and other oxidizing agents and most solvents. Polyester is generally considered to have a better overall resistance to acids or oxidizing agents.

Good resistance to the passage of electrical current. However in rope form, dirt, surface contaminants, water entrapment and the like can significantly affect dielectric properties. Extreme caution should be exercise any time a rope is in the proximity of live circuits.

No blanket working load recommendation can be made because it depends on the application and conditions of use, especially potential danger to personnel. It is recommended that the user establish working loads and safety factors based on professional and experienced assessments of risks. The working load is a guideline for the use of a rope in good condition for non-critical applications and should be reduced where life, limb, or valuable property is involved, or exceptional service such as shock, sustained loading, severe vibration, etc.

The Cordage Institute specifies that the Safe Working Load of a rope shall be determined by dividing the Minimum Tensile Strength by the Safety Factor. Safety factors range from 5 to 12 for non-critical uses, 15 for life lines.

PRODUCT DESCRIPTION: Multiline II is a 3-strand composite rope, its unique construction combines filament and staple/spun polyester wrapped around a polyolefin core (smaller than 1/2" diameter does not have polyolefin core). Multiline II feels and handles like manila, yet provides greater durability, higher strength, lighter weight, and a consistent supple feel over time.

Tensile strengths - Are approximate average for new, unused ropes. To estimate the minimum tensile strength of a new rope, reduce the approximate average by 15% (Cordage Institute defines minimum tensile strength as two standard deviations below the average tensile strength of the rope).

Good resistance to most minerals / organics, acids, weak alkalis, bleaches and other oxidizing agents and most solvents. Polyester is soluble in 95% sulfuric acid or strong alkaline"s at boil. Polyolefin is soluble in concentrated chlorosulphonic and sulfuric acids.

Olsen Chain & Cable wire rope and cable slings allow you to safely lift even the most difficult loads. Cable and wire rope slings are manufactured with various grades of wire rope with different rope lays (the direction the wires and strands are twisted). Olsen Chain & Cable also manufactures Independent Wire Rope Core (IWRC) or fiber core.

Olsen wire rope and cable slings allow you to safely lift even the most difficult loads. They are strong, safely grip and lift some hot materials, and are built to better tolerate abrasive wear. We produce various types, including:

Wire rope slings are manufactured with various grades of wire rope using different rope lays (the direction the wires and strands are twisted). Olsen Chain & Cable wire rope slings are strong, bend without distortion, safely grip and lift even hot materials and are built to handle abrasive wear. We produce various types, including Independent Wire Rope Core (IWRC) or fiber core.

If fiber core wire rope slings are exposed to temperatures above 180° F (82° C), retire these slings. For metallic core wire rope slings of any grade, follow manufacturer’s recommendations on use at temperatures above 400° F (204° C) or below minus 40° F (minus 40° C).

Most wire rope slings are made of Independent Wire Rope Core (IWRC) or fiber core. Fiber core is a bit more flexible but less resistant to environmental damage. Wire rope core has great strength and is more resistant to heat damage.

Properly match components. Ensure that the fitting is the right shape and size so it accurately seats in the hook or lifting device. For multiple-leg slings used with nonsymmetrical loads, have a qualified person do an analysis so you don’t overload any leg. Select multiple-leg slings according to OSHA guidelines for wire rope slings.

OSHA rates loads based on material strength, design factor, type of hitch, angle of loading, diameter of curvature over which the sling is used and fabrication efficiency. Never exceed the working load limit and avoid shock loads. Refer to OSHA guidelines for wire rope sling rated loads.

Properly hitch slings, pad sharp edges, balance loads, don’t drag slings, keep them free of knots or twists and don’t pull a sling from under a load when the load is on the sling.

Have each person who will use your wire rope sling know and follow its type of load, hitch and rated load capacity. Contact us for clarification. Follow other safe operation procedures, including selecting the right sling, keeping people safe distances away from the sling and its load during movement, properly rigging loads and inspecting all slings daily and according to OSHA-approved ASME guidelines.

Do not use worn or damaged slings or attachments. Discard or refurbish them. Use damaged slings only after they are reconditioned, and proof tested by the sling manufacturer or a qualified refurbishing source. Keep certificates of proof test.
