Ingersoll Rand HA1 Manuel D'installation page 4

Prior to installing the hoist, carefully inspect it for possible shipping
damage.
Hoists are supplied fully lubricated from the factory. Before operation
all oil levels must be checked and/or topped off with the proper type of
oil recommended in the "LUBRICATION" section. Lubricate load
chain before initial hoist operation.
CAUTION
• Owners and users are advised to examine specific, local or other
regulations which may apply to a particular type of use of this
product before installing or putting hoist to use.
WARNING
• A falling load can cause injury or death. Before installing, read
"SAFE OPERATING INSTRUCTIONS".
Remove cover from the shipping crate. Carefully remove steel straps.
On units equipped with a trolley, carefully position wire rope sling
around the hoist trolley side plates and slowly lift hoist assembly.
Constantly monitor the position of the hoist and trolley to ensure the
load is balanced and secure. On hook mounted units lift into position by
using top hook of the hoist.
Attach chain container to hoist with chain container pin and connect
the container suspension hook as required.
Hoist
The supporting structures and load-attaching devices used in
conjunction with this hoist must provide adequate support to handle all
hoist operations plus the weight of the hoist and attached equipment.
This is the customer's responsibility. If in doubt, consult a registered
structural engineer.
Hook Mounted Hoist Installation
Place hook over mounting structure. Make sure hook latch is engaged.
Ensure the supporting member rests completely within the saddle of the
hook and is centered directly above the hook shank.
CAUTION
• Do not use a supporting member that tilts the hoist to one side or
the other.
Trolley Mounted Hoist Installation
WARNING
• Depending on the size of hoist selected it could weigh as much as
640 kg (HA1) or 2116 kg (HA2). If parts of the trolley or hoist are
dropped, they could cause injury or damage property. Adequately
support the hoist and trolley when lifting them into place on the
beam.
Installing Over the End of the Beam
Preadjust trolley width for the beam flange measurement. Refer to
"Installing from Underneath the Beam". Remove the rail stop and slide
trolley on end of the beam. Reinstall rail stop. If this procedure cannot
be used, due to insufficient space or fixed limit stops, the trolley must
be installed from underneath the beam using the procedure which
follows.
Installing from Underneath the Beam
1. Measure beam flange width and compare with measurement
between trolley wheel flanges. The correct total clearance between
the beam and the trolley wheel flanges is 2 to 5 mm (1/16 to 3/16
in). Refer to Dwg. MHP0682. To adjust trolley wheel spacing
remove cotter pins and pins at side plate. Remove adjusting
spacers and side plate and add or subtract an equal number of
adjusting spacers on suspension shafts between top frame and side
plates on HA1 units; add or subtract an equal number of adjusting
spacers between suspension yokes and side plates on HA2 units.
Ensure that the same spacer configuration is used on either side of
the hoist top frame.
INSTALLATION
2. When desired trolley wheel spacing measurement is achieved,
carefully position wire rope sling around the hoist trolley side
plates and slowly lift hoist and trolley assembly into place beneath
the beam flange. Press side plates together on beam. Trolley
wheels must rest on top of the beam flange.
• To avoid an unbalanced load which may damage the trolley, the
hoist must be centered under the trolley by the spacers.
3. Slide remaining adjusting spacers over the free end of the
suspension shafts (HA1) or suspension yokes (HA2). Insert pins
into the holes in the suspension shafts. Secure by installing cotter
pins and bending ends apart.
4. The pin and outside spacers must hold the trolley to the
adjustment in step 1. If the side plates can be spread farther apart,
install additional outside spacers between side plate and the pin.
• Trolley wheels ride on the top of the lower flange of the beam.
5. If trolley is equipped with guide rollers measure beam flange
width and compare with measurement between guide rollers. Side
roller spacing measurement should be 2 to 5 mm (1/16 to 3/16 in)
greater than beam flange width.
6. Ensure beam stops are installed prior to operating hoist and
trolley.
7. Prior to placing into service test the trolley. Check that the trolley
side plates are vertical. Raise a load equal to the rated capacity of
the hoist 130 to 180 mm (6 to 7 in) off the floor and operate the
trolley along the entire length of the beam.
Chain Container
When installing a chain container, refer to the manufacturers
installation Instructions for Chain Containers.
• Allow chain to pile naturally in the chain container. Piling the
chain carelessly into the container by hand may lead to kinking or
twisting that will jam the hoist. When feeding chain into the chain
container begin with the chain stopper end of the chain so that it
piles naturally.
1. Check the chain container size to make sure the length of load
chain is within the capacity of the chain container. Replace with a
larger chain container, if required.
2. Attach chain stopper to the last link of the load chain free end.
3. Attach the chain container to the hoist.
4. Run bottom block to lowest point and run hoist in up direction to
feed the chain back into the container.
Free End of Load Chain
1. Ensure chain stopper is installed in the last link on the free end of
the load chain.
2. The opposite end of the load chain must be attached to the hoist or
bottom hook assembly.
