28 IMT Electric Cranes Operation & Safety Manual # 99904381
Lifting a Load:
1 Position the crane as close to the job as possible on a firm, dry and level surface. Avoid
overhead obstructions on the work side of the unit.
2 Set the auxiliary (parking) brake. Make sure the vehicle engine is on and the transmission is
in park or neutral.
3 Make sure the crane electric power switch, located in the crane remote storage cabinet, is
turned to the "ON" position.
4 See the Electric Crane Controls (see "IMT Electric Crane Controls" on page 29) section for
information on how to move a load using your controls.
5 Before conducting any boom operations, make sure vehicle is stable. Extend both
stabilizers on carrier vehicle. Level the vehicle side to side. Provide blocks if necessary to
level the unit on sloping ground or bearing pads if the stabilizers tend to sink into soft terrain
or hot asphalt. Some concrete or asphalt surfaces are relatively thin and cannot withstand
the stabilizer loading. Concrete can break through and cause instability.
WARNING
Avoid injury or equipment damage! Do NOT
attempt to handle a load if the stabilizers are
unable to make solid contact with the ground.
Stability over the front (without front stabilizers) can be hampered by raising the vehicle
excessively. Use extreme caution when operating in areas around the truck which are not
supported by stabilizers because of cushion of tires and springs. When swinging loads from
areas supported by stabilizers, use extreme caution because of potential sudden shifting of
the support point. Always keep the load as close to the ground as possible.
CAUTION
Avoid injury or equipment damage! Do NOT
attempt to rotate the crane before placing it in
the deployed position.
6 Raise the lower boom.
7 Rotate the boom to the selected location. If the crane is equipped with a winch, be sure to
lower the hook block to an adequate length to allow for extended boom length before
extending any telescoping boom sections.
