4. WIRE ROPE
4.1 Wire Rope Terminations
1. To prepare the end of IWRC wire rope for insertion, cut back the steel center at least
2” (51 mm) to allow for independent movement of the core. Braze and rough shape the
end of the wire rope to form a smooth, tapered, bullet shape no more than 1/4” (6.4 mm)
long.
DO NOT
cool the end of the hot wire rope in water or oil as this makes the end
brittle and may cause it to break off. Oil the bullet after it cools to prevent rusting.
ALL DIMENSIONS ARE IN INCHES

2. Use a heavy-duty thimble for the primary suspension wire rope and follow the
manufacturer’s requirements for termination of the wire rope hardware that you are using.
3. In situations where it is not possible to lower the platform to the ground, secure the tail
line with a suspension loop, as shown below, to prevent the platform from sliding off the
suspension ropes. Before rigging in such a situation, consult a safety professional.
