THEORY OF OPERATION - CONTINUED
LIFTING BOOM AND TOPHANDLER
The lifting boom and tophandler is an electro-hydraulic operated heavy-duty telescoping boom and spreader assembly,
designed to lift, move, and stack/unstack 20-40 ft (6.1-12.2 m) ISO containers. The operator joystick provides complete con-
trol of the lifting boom and tophandler during container handling operations. The boom provides lifting/lowering, extending/
retracting operations. The tophandler or spreader provides for sideshifting, rotation, forward/rear tilting, left/right tilting, and
load leveling and locking operations. The tophandler also provides interface capability with a forklift attachment.
The forklift kit is attached to the tophandler twistlocks and two hydraulic hose quick disconnects. Forklift operation is
controlled from the tophandler joystick to include adjustable forktines. The forktines and vertical support beams fold under the
forklift framework for transport.
