OPERATION
The four most important aspects of hoist operation are:
1.
Follow all safety instructions when operating the hoist.
2.
Allow only people trained in safety and operation of this
product to operate the hoist.
3.
Subject each hoist to a regular inspection and maintenance
program as outlined in ASME B30.16.
4.
Be aware of the hoist capacity and weight of load at all
times.
Operators must be physically competent. Operators must have
no health condition which might affect their ability to act, and
they must have good hearing, vision and depth perception. The
hoist operator must be carefully instructed in his or her duties
and must understand the operation of the hoist, including a study
of the manufacturer's literature. The operator must thoroughly
understand proper methods of hitching loads and should have a
good attitude regarding safety. It is the operator's responsibility
to refuse to operate the hoist under unsafe conditions.
Initial Operating Checks
Hoists are tested for proper operation prior to leaving the
factory. Before the hoist is placed in service the following initial
operating checks should be performed.
1.
Check for air leaks in the supply hose and fittings to
pendant, as well as from pendant to manifold.
2.
When first running the hoist motor, some light oil should be
injected into the inlet connection to allow good lubrication.
3.
When first operating the hoist it is recommended that the
motor be driven slowly in both directions for a few
minutes.
4.
Inspect hoist performance when raising, moving and
lowering test loads. Hoist must operate smoothly and at
rated specifications prior to being placed in service.
5.
Check that hook movement is in the same direction as
arrows and pendant control labels.
6.
Raise and lower a light load to check operation of the hoist
brake.
7.
Check hoist operation by raising and lowering a load equal
to the rated capacity of the hoist a few inches (cm) off the
floor.
8.
Check to see that the hoist is directly over the load. Do not
lift the load at an angle (side pull or "yard").
9.
Check to see the hoist is securely connected to the
supporting member.
10. Check to see that the load is securely inserted in the hook,
and that the hook latch is engaged.
WARNING
• Allow only personnel trained in safety and operation of this
product to operate hoist.
• The hoist is not designed and not suitable for lifting,
lowering or moving people. Never lift loads over people.
• The hook latch is intended to retain loose slings or devices
under slack conditions. Hook latches are not intended to be
anti-fouling devices, so caution must be used to prevent the
latch from supporting any of the load.
Pendant
The pendant is a remote control that allows the operator to
control the positioning of a load. It will allow the operator to
control hoist movements from a distance, thereby allowing exact
positioning of a hook.
The two-lever pendant controls raising and lowering of the
hook. Refer to Dwg. MHP1546.
(Dwg. MHP1546)
Emergency Stop
The Emergency Stop button, when activated, will immediately
stop all operations of the hoist. The Emergency Stop button will
remain depressed after activation.
To reset Emergency Stop button, twist (rotate) Emergency Stop
button clockwise until button releases and spring returns to its
original position. Depress "ON" button.
