CARTRIDGE AS 1869084 - Caterpillar

All winches are rated at bare drum line pull. As the cable drum fills, the line pull will decrease (loss of leverage) as the line speed increases (larger circumference). Therefore, install the minimum length of cable possible for your application so the winch will operate on lower layers (smaller diameter) and deliver the maximum line pull.Using larger cable will not always increase strength as the larger cable may be more prone to bending fatigue failure than smaller wire rope. Consult your wire rope supplier for his recommendations for the wire rope and other rigging which best suits your application.
Winch cable anchors (ferrules and ferrule pocket) are NOT designed to hold rated loads. Winch loads applied directly to the cable anchor may cause the cable to pull free and result in the sudden loss of load control and cause property damage, injury or death. A minimum of 5 wraps of cable must be left on the drum barrel to achieve rated load. Do not use knots to secure or attach winch cable. We suggest that the last 5 wraps of cable be painted bright red to serve as a visual warning.
Installation Of Spiral Ferrules
Re-useable, field installed spiral ferrules are available from your Caterpillar or wire rope dealer. These ferrules are for use with six strand, IWRC (Independent Wire Rope Core) type wire rope. Refer to Specifications on page 9. Insert cable through the small opening of the ferrule. Spread strands and insert spiral wedges between strands and core. Lay strands in individual grooves in spiral wedges. Tap wedges and cable into ferrule leaving approximately 3/8 in. (10 mm) extending from the top. The first load will seat the cable and wedges securely in the ferrule.
