Main Hoist Rope:
Main hoist rope is 5/8” diameter, Compact 35 rotation resistant rope, RRL lay, 2160
Grade, minimum breaking strength 56,400 lbs (251 kN), 425’ (130 m) long. Weight per
foot is 0.88 lbs (1.31 kg per m). Note that rope weight is not included in load calculations.
Downhaul Weight and Hook:
Downhaul weight and 14,000-pound (6350 kg) rated swivel hook to use with wedge
socket on 5/8-inch (16 mm) load line. Specially designed to work with the anti-two-block
system and to clamp the dead end of the rope. Weighs 180 pounds (82 kg).
Anti-Two-Block Device:
Prevents damage to hoist rope and/or machine components from accidentally pulling
sheave block or downhaul weight against boom tip. Consists of trip arm at boom tip
which is moved upward, by sheave block or downhaul weight, as hook approaches boom
tip. Trip arm actuates electric switch, which is connected through cable reel mounted on
boom, to solenoid dump valve control system. This system will stop HOIST RAISE,
TELESCOPE EXTEND, and BOOM LOWER. No other circuits are affected. These
circuits are returned to normal operation by operating the HOIST LOWER or
TELESCOPE RETRACT control.
Rated Capacity Limiter:
Operational aid that warns operator of impending overload with audible and visual
signals. Has read-outs for load, boom angle, boom length and load radius. In the event
of an overload, it will block the following boom functions: HOIST RAISE, TELESCOPE
EXTEND, and BOOM LOWER. These circuits are returned to normal by lowering load
to a safe resting place with hoist, or by retracting or raising boom to a shorter load radius.
There is an override function on the display of the RCL system in the operator
compartment.

Chart when boom extension is in the stowed position. Includes trip arm for Anti-Two-
Block device. Boom extension will tilt through 3 positions: in-line, 15° offset and 30°
offset. Net Weight: 775 pounds (350 kg)
