OPERATION
The four most important aspects of hoist operation are:
1.
Follow all safety instructions when operating hoist.
2. Allow only people instructed in safety and operation on this
product to operate hoist.
3. Subject each hoist to a regular inspection and maintenance
procedure.
4. Be aware of the hoist capacity and weight of load at all
times.
WARNING
• Do not use this hoist for lifting, supporting or transporting
people or lifting or supporting loads over people.
Operators must be physically competent. Operators should have
no health condition which might affect their ability to react, and
they must have good hearing, vision and depth perception. The
hoist operator must be carefully instructed in his duties and must
understand the operation of the hoist, including a study of the
manufacturer’s literature. The operator must be aware of 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 into 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, and from pendant to manifold.
3. When first running the hoist or trolley motors a small
amount of 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 load(s). Hoist and trolley must operate
smoothly and at rated specifications prior to being placed in
service.
7. Check that trolley (if equipped) and hook movement is the
same direction as arrows or information on the pendant
control.
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 4 to 6 inches (100 to 150
mm) 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 that 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
• The hook latch is intended to retain loose slings or devices
under slack conditions. Hook latches are not intended to be
an antifouling device, so caution must be used to prevent the
latch from supporting any of the load.
Hoist Controls
Pendant Controls
The HLK hoist can be supplied with an optional manual pull
chain control or a one, two or three function pendant depending
on application. For detailed information on these products refer
to Ingersoll-Rand Manual Form Number P6778 or contact your
nearest distributor or the factory.
Operation of the hoist is the same for all pendants listed in this
section:
1.
To lift a load, depress the hoist pendant raise lever.
2. To lower a load depress the hoist pendant lower lever.
3. To throttle lift or lowering speed, regulate the amount the
pendant lever is depressed. Depress lever completely for
maximum speed; depress lever partially for slower speeds.
4. To stop lift or lowering function, release the lever. Lever
will spring return to off and hoist motor will stop.
Single Function, Two Lever Pendant
Refer to Dwg. MHP0427.
The two lever pendant is the standard pendant supplied with the
HLK and is designed to provide hoist operation only. Hoist
operation must correspond to the directions indicated by the
arrows located on the pendant levers.
