WRECKER BOOM OPERATION
The wrecker boom is probably one of the most useful accessories on your
HDR. It allows the operator to perform lifting and retrieval tasks that cannot
be performed in any other way. Safe operation of the wrecker boom demands
knowledge of the controls and the boom functions. Review the boom safety
section of this manual and USE CAUTION AND GOOD JUDGEMENT!
Position the recovery vehicle to best take advantage of the leverage the
boom affords. A vertical lift is the best and most efficient, so attempt to
place the boom over the work. This reduces the chance of the work breaking
free and swinging during the lift. Place the recovery vehicle as close as
possible to the work. A shorter boom extension will result in less rear axle
loading. When pulling, align the recovery vehicle with the work so that the
direction of pull is in line with the length of the truck. Always use more
stabilizing lines than pull lines. If the front wheels of the recovery vehicle
raise completely from the ground,
Stop! And Re-Rig.
WARNING:
Do not exceed the working limit of the wire rope. Use snatch blocks
and multiple lines to reduce the load on the wire rope. Always
apply an equal load in the opposite direction of the pull to stabilize
the load.
DANGER:
Do not swing the wrecker boom without extending the outrigger/
stabilizers.
WARNING:
Refer to load charts prior to performing any lifting or recovery work.
