3.
Check the wire ropes before use. Thoroughly check the wire ropes for problems such as kinks,
knots, and broken strands. Do not start lifting unless the wire ropes have been verified and have no
problems. If you cannot make a correct evaluation or judgment, entrust an expert to inspect.
4.
To lift the compressor, attach the wire ropes to the attached eyebolts using appropriate shackles
and hooks. The eyebolts are only used for lifting the compressor. Do not use the eyebolts to lift the
compressor with any attached apparatus.
The compressor eyebolts must not be used to lift the package unit. To lift the package
unit, use the lifting chains on the compressor unit base periphery or other lifting
devices provided on the compressor unit base.
5.
Check the transportation route for any obstacles in consideration of the compressor size.
6.
Before lifting, check that the hook is located above the gravity center of the compressor.
7.
Instruct all workers to move from near the work site before lifting.
8.
Before lifting the compressor, alert all workers on the site of possible dangers of the lifting process
by signal (such as calling at the beginning of the work or making a signal by hand). Do not lift the
compressor unless the signals are completely understood by all personnel working together.
9.
Slowly windup the wire ropes until shortly before the compressor leaves the ground.
10.
Then, wind up the wire ropes a little further until the compressor is slightly away from the ground
and check that the compressor is balanced. If the compressor is inclined, return the compressor to
the ground and correct the inclination by adjusting the wire ropes. Then, restart the lifting operation.
11.
Make sure to wind up the compressor slowly. Lifting it too quickly may damage the lifting equipment
including the wire ropes or part of the compressor.
12.
When lifting the compressor, check the state of the wire ropes and lifting equipment. Check that the
compressor is not inclined.
13.
When moving the lifted compressor, always use guiding ropes.
14.
When moving the compressor, turn away workers from the movement direction and check safety.
15.
Do not lift the compressor above any safety aisles unless absolutely necessary.
16.
Do not put the compressor in a safety aisle. Always keep the safety aisle free of obstacles.
17.
Remove any obstacles before putting down the compressor on the ground. The compressor should
not be inclined or unstable.
18.
Before putting down the compressor on the ground, announce to the workers around the working
area.
19.
When lowering the compressor onto two or more blocks, align the tops of blocks so that the
compressor becomes stable horizontally on them.
20.
Lower the compressor slowly so that it does not get damaged due to impact.
