  1. Rope Protection 101

    Rope is one of the most versatile pieces of equipment in at-height work. Whether you are using it as a lifeline or for lifting and rigging, knowing and caring for your rope can often be the difference between life and death. We’ve discussed rope inspection and the importance of caring for your rope by washing it in previous blog posts. This week, our Gear Experts® are going to break down rope protection.

    Rope Protection: Overview


     

    Rope protection is, wait for it…, the act of protecting your rope from being damaged by things like sharp edges. It is done with the use of a piece of equipment that has been specifically designed to protect rope against edges. The most common situation that creates a need for rope protection is the inability to properly anchor your rope directly overhead. In many rescue and rope access situations your rope may have to come into contact with an edge that isn’t exactly designed to be safe for rope. Whether it’s a building, beam, or rock face, that type of contact can cause unnecessary abrasion and ultimately decrease the life of your rope.

    How to Protect Your Rope


     

    There are two major types of rope protection: rope guards and mechanical rope protectors.

    Mechanical Rope Protectors

    Petzl P68 Caterpillar Rope Protector

    Mechanical rope protectors, like the Petzl P68 Caterpillar or DBI Sala 8700302 Rope Protector, are usually made from metal links with rollers in the center. The metal links are connected by smaller links that allow for flexibility over edges. The rope can move up and down on the rollers as needed providing a smooth process and preventing any damage caused by the edges. Mechanical rope protectors are more expensive than rope guards because of their metal construction.

    Rope Guard

    Sterling SafeGuard Rope ProtectorRope guards, like the Sterling SafeGuard or the PMI Supermantle Rope Protector, are much more economically friendly and lighter than their mechanical counterparts. While each rope guard is constructed a little bit differently, the basic functionality is the same. They work by covering the rope (usually with some form of canvas) and allowing the rope to slide through the guard when it needs to move up or down an edge.

  2. Product Spotlight: Sterling Rope PDQ Tower Emergency Descent System

    In a perfect world, we would never have to talk about emergency situations. But, sometimes accidents happen and here a GME Supply we take pride in helping keep you safe on the job – and better informed about what gear can help when you need it the most. This week our Gear Experts® are going to cover the Sterling Rope PDQ Tower Emergency Descent System.

    What’s Included


     

    An emergency system isn’t very useful if it doesn’t have the gear needed to handle the situation in a safe and effective manner. So, let’s go over what is included in the Sterling Rope PDQ Tower Emergency Descent System.

    Descent Device

    This system features the Sterling Rope PDQ Control Descent Device. The PDQ Device is made from lightweight high strength aluminum and has an asymmetric cam, features hands-free lock-off, and an anti-panic feature. It weighs only 6.8 ounces and has an MBS of 13.3 kN.

    Rope

    Depending on the needs of your system you can get two different lengths of rope – 100 mm (328 ft) or 120 mm (394 ft). The rope is 6 mm XTEC Technora heat resistant high strength rope. It features a Technora sheath and the core offers maximum cut and abrasion resistance.

    Carabiners

    There are 2 ASD carabiners included in the system. They are auto-locking D-Shaped aluminum carabiners with a threaded captive eye pin and 3,600 lb gate.

    Bag

    The bag completes the system and provides an easy way to take the system up and down a tower. It is a weatherproof bag that also provides storage protection. The low profile roll top bag includes a shoulder strap for ease of transportation and has a 22-liter capacity.

    Features


     

    The Sterling Rope PDQ Escape System is lightweight and strong, making it ideal for tower, wind turbine, and other at-height applications. It is heat resistant to over 900°F, is rated up to 310 lbs., and meets ANSI Z359.4. The kit comes fully assembled and ready for fast deployment and it weighs under 10 lbs. – 8.85 lbs. to be exact.

    Mechanical Advantage


     

    If you’re looking to gain some mechanical advantage with the PDQ system you can easily pair it with the Sterling Rope PDQ Raise and Rescue Kit. The micro pulleys and anchor slings in this kit help to convert the PDQ Tower Descent kit to a mechanical advantage system for raising a fallen worker and transferring them to a lowering system.

  3. Product Spotlight: The Sterling Pocket Hauler

    Certain situations call for a single person or team to lift an object or person that they normally wouldn’t be able to lift. That’s where mechanical advantage comes in. This week our Gear Experts® are going to talk about the Sterling Pocket Hauler and how it can provide a mechanical advantage for a range of applications.

    Mechanical Advantage


     

    First things first, let’s talk a bit about mechanical advantage. Mechanical advantage is “the advantage gained by the use of a mechanism in transmitting force; specifically: the ratio of the force that performs the useful work of a machine to the force that is applied to the machine”. Basically, mechanical advantage is the number of times the device multiplies the force you apply. Need to lift 60 pounds but only strong enough to lift 30? A device with a 2:1 (2 to 1) mechanical advantage will help you achieve that lift.

    The Pocket Hauler


     

    The Sterling Pocket Hauler is a small, lightweight, simple to operate system that provides a 4:1 or 5:1 mechanical advantage. This device makes lifting extremely easy for use in rescue, adjustable directional, tensioning, or a number of other rigging needs. The Sterling Pocket Haul System comes with everything you need to get the job done. It includes:

    → (1) 50’ 8 mm Rope with a Sewn Eye;

    → (2) Aluminum Mini-double Pulleys;

    → (2) Aluminum Auto lock Carabiners;

    → (1) 6 mm Prusik Cord; and

    → (1) Screwlink Carabiner

    **The pocket hauler does not come pre-rigged. But don’t worry – we’ve got you covered. You can check out our video on how to properly rig the Sterling Pocket Hauler Below.

    Save Energy


     

    To prove how much energy the Sterling Pocket Hauler’s mechanical advantage can save you, we did an experiment. In our experiment, we used a Rock Exotica Enforcer LC1 Load Cell to test the loads. We had a volunteer rig up to the haul system and used the Load Cell to show that he was 182 pounds. The next step was to change the configuration of the Load Cell to allow it to measure how much force was required to lift the volunteer using the haul system. In the 4:1 configuration it took 50 pounds of force to lift 182 pounds of weight. In the 5:1 configuration it only took 40 pounds of force to lift 182 pounds of weight.

    See the full experiment in the below video.
