RAISING AND LOWERING THE BOOM
This floor crane utilizes a modular power unit (MPU) to control the up and down movement of the
boom and load hook. To activate the power unit, turn the power selector switch ON, pull out the
emergency stop button (E-stop) and press the appropriate control button (UP or DOWN) on either the
MPU or the handheld controller.
Pressing and holding the UP button causes oil to fill the cylinder. As oil fills the cylinder, it extends. The
moving end of the cylinder attaches to the bottom of the outer boom. As the cylinder extends, the end
of the boom and the load hook are elevated. Press the UP button until the load hook is adequately
elevated for your task.
Lower the boom by pressing the DOWN button on either the MPU or handheld controller. Release the
button when the boom is lowered to the desired point.
USING THE CRANE
1)
Carefully push the floor crane to the load.
Apply both caster brakes by pressing down on the brake
levers. See diagram below
.
2)
Attach appropriate rigging to the load. Rigging will attach to the
load hook
at the end of the boom.
3)
If necessary, adjust the position of the boom.
a.
Raise the boom by pressing the
UP button
on either the MPU of the
handheld controller.
b.
Lower the boom by pressing the
DOWN button
on either the MPU or
the handheld controller.
4)
Attach the rigging to the
load hook
. The floor
crane must be on a sound, level and dry
surface. Before raising the boom, be sure
that the load hook is centered above the
load. If the hook is not centered above the
load, the load might swing when the boom
lifts it off of the ground.
NOTE:
Rigging and all other load-engaging
equipment must be added to the weight of
the load to determine the net weight of the
load applied to the crane. The net weight
must be less than or equal to the rated load
of the crane. Rated load for each model of
crane decreases when the boom is
extended. Refer to your
SPECIFICATIONS
document (see
, or
); see also
5)
Slowly raise the load until it is suspended a
few inches above the ground. Do not
elevate the load any more than necessary.
a.
The load should not swing as it rises.
b.
The crane should not tip or rock when the
load is suspended.
c.
If the crane is unstable when the load is
suspended, do not use the crane to transport
the load. Return it to the ground and use
another means to move it.
6)
Transport the load by carefully pushing the
crane to the destination. Turn slowly. Stop
slowly to minimize load swing. Do not leave
the crane with a suspended load. Always
lower the boom until the load is entirely
supported by the ground or other surface
before leaving the crane.
