RIPCORD CABLE ROUTING

The routing of the ripcord cable from the handle to the pin determines where the lanyard connects to the cable. Most RSL attachments connect with the ripcord cable either at the yoke area or just above the ripcord pin. Generally, there is a double ring installation where the cable end of the lanyard is located. [Figure 2-53] On this particular installation, the connection is at the shoulder yoke area.

RSL LANYARD AND CONTAINER MOUNT

These two components are interactive. That is, the design of the container directly affects the design of the lanyard. Once the two above locations are determined, then the routing of the lanyard can be completed. It was originally thought that the lanyard should have a long length to allow acceleration during activation to pull the ripcord cable. This has not proven to be true and most manufacturers keep their lanyards as short as possible to prevent snagging and easier stowing.

In the past, a Velcro® pathway was used for routing the lanyard. This was either on the shoulder yoke or the reserve riser. Experience has shown that the use of Velcro® generally results in high wear and eventual damage to the webbing. [Figure 2-54] On this design, the lanyard is stiffened with a short piece of coated cable and stowed in two pockets located on the yoke area. [Figure 2-55] It is secure and has no wear points. The ripcord end of the lanyard is routed to the dual guide ring attachment location and the ripcord cable routed through the rings. [Figure 2-56] The ripcord cable is then routed to the reserve closing loop.

Figure 2-57 shows the RSL lanyard and ripcord cable at the moment of riser extension and just as the cable is loaded. A point that the rigger should be aware of is the “pigtail” configuration of the reserve ripcord that results from the use of the RSL. [Figure 2-58] Because of the sliding of the ring along the ripcord cable, a curling effect is imparted to the cable. This is a clear indication that the RSL lanyard activated the reserve. The rigger should carefully inspect the ripcord cable for any broken strands.

If any are found, the ripcord should be replaced. If not, the cable can be straightened and returned to service.

With the single side RSL, it is imperative that the main riser with the RSL attachment leave after the opposite riser. If the opposite riser stays connected while the RSL deploys the reserve, there is the possibility of a main/reserve entanglement. To ensure the correct staging of the cutaway, the release cable of the RSL side must be longer than the cable on the opposite riser. A minimum of 1" is the standard differential. [Figure 2-59]
