safety lifeline wire rope size supplier

When it comes to any at-height industry, fall protection is an important part of the job. Not to mention you will probably spend some time in situations where tying off to an appropriate anchor can be difficult. That"s why having the best lifeline is important. Our gear experts have spent years sourcing the best lifeline rope available and our hand-picked selection will help you stay safe and get the job done. We feature a range of styles, colors, lengths, and sizes of rope. You can choose a rope from 300, 600, or 1,200 foot pre-cut lengths, or if you need a custom length rope - we’ve got you covered there too. Diameters include ?, 7/16, ?, and ½ inch options and come in a variety of styles including HTP static, 3-strand, and unicore. We’ve also got a range of colors so that each lifeline can be visibly different than the others for easy identification.

Most folks think lifelines when it comes to fall protection, but if you quiz them about how these systems work or when they are good fits for an application, they come up short. So what is a cable-based fall protection system, and what are the pros and cons of lifeline systems?

Cable fall protection systems take many names, including rat lines, HLL’s, and horizontal lifelines just to name a few. In their simplest form, cable fall protection systems consist of wire rope secured by a series of terminal and intermediate anchor points. By connecting a body harness and lanyard to a shuttle traveling the length of the line, a worker can safely move along a horizontal (or vertical) plane. Cable systems are deceptively simple in design, but done properly, they are actually highly engineered fall protection systems.

In a previous post titled “Is My Horizontal Lifeline Safe?”, we shared pictures of some home-made rat lines we have encountered in the field. Lifelines made from combinations of wire rope, wire rope clips, and turnbuckles may look safe, but these home-made solutions share little in common with the engineered lifelines we design and install at DFP.

With years of knowledge, our team can supply everything from wire rope through to individual and bespoke fittings used in these systems. Some of our main components are listed below:

M12 Thread with a swaging dimension of 12.5mm. This is smaller than the standard 16mm dimension usually associated with 8mm rope, which makes it popular among engineers swaging on site using an Electro/Hydraulic hand tool.

A complete assembly of engineered components required to rig a HLLS (horizontal lifeline system). Designed specifically for use with SAS commercial anchors, these kits can also be used with other mfg. equipment when engineered by a qualified person. Each Kit contains attachment bolts, lock nuts, couplers and wire rope. Specify the HLL length, and factory swage option at time of ordering. We also offer numerous parts to achieve a HLL system that works for your products including:

Rigging Kits: our standard turnbuckle/clamps/thimbles/sliders/energy absorber for lifeline lengths up to 120’. They include everything you need for a complete installation except for the cable. Available in galvanized or stainless-steel finishes.

Turnbuckles: used in the horizontal lifeline system to adjust wire rope length and tension. Available in galvanized or stainless-steel finishes. Use 1 turnbuckle in systems up to 60’ and 2 turnbuckles in systems 60’ – 120’.

Lifelines, safety belts, and lanyards shall be used only for employee safeguarding. Any lifeline, safety belt, or lanyard actually subjected to in-service loading, as distinguished from static load testing, shall be immediately removed from service and shall not be used again for employee safeguarding.

Lifelines shall be secured above the point of operation to an anchorage or structural member capable of supporting a minimum dead weight of 5,400 pounds.

Lifelines used on rock-scaling operations, or in areas where the lifeline may be subjected to cutting or abrasion, shall be a minimum of 7⁄8 -inch wire core manila rope. For all other lifeline applications, a minimum of 3⁄4 -inch manila or equivalent, with a minimum breaking strength of 5,000 pounds, shall be used.

Safety belt lanyard shall be a minimum of 1⁄2 -inch nylon, or equivalent, with a maximum length to provide for a fall of no greater than 6 feet. The rope shall have a nominal breaking strength of 5,400 pounds.

All safety belt and lanyard hardware shall be drop forged or pressed steel, cadmium plated in accordance with type 1, Class B plating specified in Federal Specification QQ-P-416. Surface shall be smooth and free of sharp edges.

All safety belt and lanyard hardware, except rivets, shall be capable of withstanding a tensile loading of 4,000 pounds without cracking, breaking, or taking a permanent deformation.

Body belt means a strap with means both for securing about the waist and for attaching to other components such as a lanyard used with positioning systems, travel restraint systems, or ladder safety systems.

Deceleration distance means the vertical distance a falling employee travels from the point at which the deceleration device begins to operate, excluding lifeline elongation and free fall distance, until stopping. It is measured as the distance between the location of an employee"s body harness attachment point at the moment of activation (at the onset of fall arrest forces) of the deceleration device during a fall, and the location of that attachment point after the employee comes to a full stop.

Equivalent means alternative designs, equipment, materials, or methods that the employer can demonstrate will provide an equal or greater degree of safety for employees compared to the designs, equipment, materials, or methods specified in the standard.

Free fall distance means the vertical displacement of the fall arrest attachment point on the employee"s body belt or body harness between onset of the fall and just before the system begins to apply force to arrest the fall. This distance excludes deceleration distance, lifeline and lanyard elongation, but includes any deceleration device slide distance or self-retracting lifeline/lanyard extension before the devices operate and fall arrest forces occur.

Lanyard means a flexible line of rope, wire rope, or strap that generally has a connector at each end for connecting the body belt or body harness to a deceleration device, lifeline, or anchorage.

Lifeline means a component of a personal fall protection system consisting of a flexible line for connection to an anchorage at one end so as to hang vertically (vertical lifeline), or for connection to anchorages at both ends so as to stretch horizontally (horizontal lifeline), and serves as a means for connecting other components of the system to the anchorage.

Personal fall arrest system means a system used to arrest an employee in a fall from a walking-working surface. It consists of a body harness, anchorage, and connector. The means of connection may include a lanyard, deceleration device, lifeline, or a suitable combination of these.

Rope grab means a deceleration device that travels on a lifeline and automatically, by friction, engages the lifeline and locks so as to arrest the fall of an employee. A rope grab usually employs the principle of inertial locking, cam/lever locking, or both.

Self-retracting lifeline/lanyard means a deceleration device containing a drum-wound line that can be slowly extracted from, or retracted onto, the drum under slight tension during normal movement by the employee. At the onset of a fall, the device automatically locks the drum and arrests the fall.

Travel restraint (tether) line means a rope or wire rope used to transfer forces from a body support to an anchorage or anchorage connector in a travel restraint system.
