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 in the hydraulic circuit. This valve will dump the HOIST
RAISE, TELESCOPE EXTEND, BOOM LOWER, SWING LEFT and SWING RIGHT
circuits. No other circuits are affected. These circuits are returned to normal operation
by operating the HOIST LOWER or TELESCOPE RETRACT control.

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, the following boom functions stop: HOIST RAISE, TELESCOPE
EXTEND, BOOM LOWER, SWING LEFT and SWING RIGHT. These circuits are
returned to normal by lowering load to a safe resting place with hoist or by retracting
boom or raising boom to a shorter load radius. There is a key-operated override switch
under the dashboard.
