OPERATION GUIDELINES
WINCHES
TURNTABLE WINCH
The turntable winch is located in the turntable behind the rear of the boom.
Boom movement, articulation or extension will cause load line to move relative to the boom tip sheave. Be
aware you must payout or pull in on the winch line to prevent contact of the hook or load being pulled into the
sheave end.
TURNTABLE WINCH
BOOM TIP WINCH
Some Digger Derricks are equipped with a boom tip winch. This winch is mounted on the outer end of the
second boom section and travels in and out with the second section. The third section is provided with a
sheave arrangement to accept the winch line from the boom tip winch.
BOOM TIP WINCH
When extending either the second section or the third section, always pay out the
winch line to maintain clearance between the boom tip and the winch line hook/
load. Contact between the boom tip and the winch line hook/load can cause
damage to the boom or break the winch line and cause serious injury or death.
When the winch is attached to the second section, always pay out the winch line
when extending the third section to maintain clearance between the boom tip and
the winch line hook/load. Contact between the boom tip and the winch line hook/
load can cause damage to the boom or break the winch line and cause serious
injury or death.
