Built around the all-new CMC CLUTCH™ by Harken Industrial™, the Double CLUTCH Twin Tension Rope System (TTRS) Kit delivers best practice twin tension hauling/lowering for any rescue or training operation. This kit comes with two color-coded RigTech Packs™ that each carry independent hauling/lowering systems designed to work together in mirrored or nested configurations. Rescuers can use these components to build mechanical advantage systems on both 200ft 11mm CMC G11™ Lifelines simultaneously including a 3:1, 3:1 with change of direction, or complex 5:1. These ready-to-go systems minimize gear sorting and allocation. Rescue teams can shoulder their RigTech Packs knowing they have everything they need to quickly and efficiently deploy a best practice TTRS.
The smooth, efficient action of the CLUTCH allows rescuers to haul more easily and lower with more control. Additional built-in features of the CLUTCH make it ideal for this kit including the ratcheting rotating sheave, Anti-Panic brake, force limiting protection, and integrated becket. When two CLUTCH devices are brought together in the Double CLUTCH Technique (aka “Double CLUTCH-ing”), rescuers can maintain nearly equal tension on both lines so that the load, often involving a rescuer, litter and a victim, is shared across two rope systems, reducing the risk of a single line failure. If a catastrophic event such as single line failure does occur, the Double CLUTCH Technique is preferable to a traditional slack belay because it prevents 100% load transfer on the slack belay line and thereby limits shock and extension in the system.
