outriggers retracted (i.e., on rubber).
Failure to follow this warning could result
in a tire exploding causing personnel
injury and/or equipment damage.
CRANING OPERATIONS
GENERAL SAFETY PRECAUTIONS
Most accidents involving mobile hydraulic cranes are
caused by:
-
crane out of level,
-
bad surface conditions,
-
outriggers used improperly or not used at all,
-
unstable blocking under outrigger floats, and
-
improper crane operation.
Dont interfere with the proper operation of aids and/or
warning devices. Check them regularly and see they get
proper care.
Operate engine at full governed RPM (2500) during
performance of all crane operations.
Watch tail--swing of counterweight, especially if there are
people or obstacles in the area.
Stay clear of sheaves, holes in telescoping boom and
other potentially dangerous areas whenever the crane is
in operation.
Pinch points are impossible to eliminate. Keep all
portions of your body away from cable drums, sheaves,
pulleys, lift cylinders and other moving parts of the crane.
Never operate the crane with less than one complete
layer of rope on the hoist drum.
NEVER permit anyone to ride load, slings, hooks, etc.,
for any reason.
Allow no one to ride on the crane, carrier deck, engine
compartment, etc.
Operate the crane only from the operators seat.
Operating from any other position, such as reaching in a
window, creates a safety hazard.
Never work the crane when darkness, fog or other
visibility problems make such operating unsafe.
Always check capacity of the crane as shown on load
chart before making any lifts.
Report any crane damage immediately. Do not operate
crane until inspected and approved for use.
ESTABLISHING A SIGNALPERSON
A qualified signalperson should be on site at all times
when:
-
working in vicinity of power lines,
-
you cannot clearly see the load at all times, and
-
moving the crane in direction in which you cannot
clearly see the path of travel.
