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 .
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. After installation of trolley mounted hoists, check to
ensure the hoist is centered below the trolley.
2. Check for air leaks in the supply hose and fittings to
pendant, as well as from pendant to manifold.
3. When first running the hoist or trolley motors, some light
oil should be injected into the inlet connection to allow
good lubrication.
4. When first operating the hoist and trolley it is
recommended that the motors be driven slowly in both
directions for a few minutes.
5. Operate the trolley along the entire length of the beam.
6. Inspect hoist and trolley performance when raising,
moving and lowering test loads. Hoist and trolley must
operate smoothly and at rated specifications prior to
being placed in service.
7. Check that trolley and hook movement is in the same
direction as arrows and pendant control labels.
8. Raise and lower a light load to check operation of the
hoist brake.
9. Check hoist operation by raising and lowering a load
equal to the rated capacity of the hoist a few inches (cm)
off the floor.
10. Check operation of limit devices.
11. Check to see that the hoist is directly over the load. Do
not lift the load at an angle ("side pull" or "yard").
12. Check to see the hoist is securely connected to the
overhead crane, monorail, trolley or supporting
member.
13. 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 and trolley.
• The hoist is not designed and not suitable for lifting,
lowering or moving people. Never lift loads over people.
WARNING
• 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 four lever
pendant controls both hook and trolley positions.
Emergency Stop
The Emergency Stop button, when activated, will
immediately stop all operations of the hoist and trolley.
The Emergency Stop button will remain depressed after
activation.
To reset four lever pendants Emergency Stop button twist
(rotate) Emergency Stop button clockwise until button
releases and spring returns to its original position. Depress
"ON" button.
