Cotter Pin Puller

A cotter pin puller (Figure 15-12) is an S-shaped tool used to install or to remove cotter pins. One end is used to insert through the cotter pins for extracting. The other end is used for spreading the cotter pin. The shank is beveled square for easy handling and for a firm grip. This type is 7 inches long.

Figure 15-12 — Cotter pin puller.


Blocks (Figure 15-13) are constructed for use with fiber line and wire rope. Wire rope blocks are heavily constructed and have a large sheave with a deep groove. Fiber line blocks are generally not as heavily constructed as wire rope blocks and have small sheaves with shallow, wide grooves that revolve on a pin.

Figure 15-13 — Blocks.

Blocks fitted with one, two, three, or four sheaves are often referred to as single, double, treble, and quadruple blocks, respectively. Blocks are fitted with a varying number of attachments, depending on their particular use. Some of the most commonly used fittings are hooks, swivel or loose side, sister hooks, shackles, eyes, and rings. Depending on the various combinations of blocks available to do the job, the mechanical advantage can be increased indefinitely.

All line used in rigging should be good grade manila or the equivalent, and all wire should be plow steel or the equivalent.

Chain Assembly

The chain assembly (Figure 15-14) is a heavy duty linked chain with a grab hook at one end and a ring at the other. The chain assembly is used for such applications as towing vehicles, slinging loads, and hauling objects. The chain assembly is available in a wide variety of lengths and link sizes depending on the nature of the use.

Figure 15-14 — Chain assembly.

Cable Jaw Grip

The cable jaw grip (Figure 15-15) is used to tighten or stretch wires or cables for various operations. Examples of application include removing kinks or bends in cables, tightening cables on loads or bales, or for cleaning and oiling of cables. Cable grips, depending on their application, vary in size and design.

 Figure 15-15 — Cable jaw grip.

Tension Puller

Like the cable jaw grip, the tension puller (Figure 15- 16) is used to tighten or stretch cables. The tension puller has strong cable attached to a cable notch gear. At the end of the cable is a hook. This hook can be attached to the eyelet of the cable to be tightened. Tension is then applied to the cable by moving the tension handle in an up and down motion.

Figure 15-16 — Tension puller.

Trip Wire Grapnel

The trip wire grapnel (Figure 15-17) is a metal weight resembling three or four fish hooks, with a common shank ending in an eye. The hooks spread out in different directions at the other end of the shank. Attached to the eye portion of the shank is a marlin cord of varying length. The trip wire grapnel is designed to clear trails, tunnels, caves, and buildings of trip wires, booby traps, and mines. It fits into a 30 round magazine pouch between the magazines. A small tool is included to pop off the tips of the arms should sharp points be required.
