Figure 2A - Reeving for 20 Tonne hoist
Operate the hoist with no load and then a light load of approximately
50 pounds to make sure it operates properly and the brake holds the
load when the hand chain is released, then operate with a rated load
as shown on the nameplate.
GENERAL
1. The hoist must always be rigged to lift in a straight line from hook
to hook. The hoist must always be free to swivel on the upper
hook. Under no condition should the hoist frame be allowed to
bear on any support when in use, as this would cause bending
of the hook or frame and damage the unit.
2. When preparing to lift or move a load, be sure that the
attachments to both hooks are firmly seated in the saddles
of the hooks. Avoid off center loading of any kind especially
loading on the tip of the hook. Also, observe that the chain
hangs straight (without twist) from hoist to lower hook.
3. When lifting, raise the load only enough to clear the floor or
support, and check to be sure brake will hold load and that
attachments to the load are firmly seated. Continue the lift
only after you are assured the load is free of all obstructions.
4. Do not load beyond the rated capacity of the hoist. Rated
capacity can be achieved with the following hand chain pulls:
Hand Chain Pull
Hoist Capacity
to Lift Rated Load
(Tonnes)
(Lbs.)
1/2 44
1 54
2 74
3 92
5 76
10 102
15 2x76
20 2x102
Since these hand chain pulls can easily be applied by one person,
under no circumstances should more than one person operate the
hoist hand chain.
This hoist is equipped with a load limiting device. The presence
of this device does not authorize the application of overloads.
Always select a hoist whose load rating is in excess of the load
to be handled. If the handwheel slips while operating, reduce
load or use correct capacity hoist.
NOTE:
The load limiting device incorporated in this hoist is effective only
when the overload is being lifted or pulled through the operation
of the handwheel. It will not protect against externally applied
overloads.
5. Do not wrap load chain around the load or bring the load in
contact with the hoist. Doing this will result in the loss of the
swivel effect of the hook which could mean twisted chain and
a jammed liftwheel. The chain could be damaged at the hook.
6. Stand clear of all loads and avoid moving a load over the heads of
other personnel. Warn personnel of your intention to move
a load in their area.
7. Do not leave the load in the air unattended.
8. Do not lower the hook to a point where the chain becomes
taut between the liftwheel and loose end connector
Power operation may result in structural damage or premature
wear that may cause a part to break and allow the load to fall.
TO AVOID INJURY:
Operate CM Hurricane 360 Hoists using hand power only.
®
9. Do not run the lower hook block into the hoist frame.
Frame and/or chain guide damage may result.
10. The hoist has been designed for manual operation only.
11. Do not use this or any other overhead materials handling
equipment for lifting persons.
12. Do not allow the load to bear against the hook latch.
The latch is to help maintain the hook in position while
the chain is slack before taking up slack chain.
13. Never operate the hoist when flammable materials or
vapors are present. Sharp contact between metal parts
can produce sparks that can cause a fire or explosion.
14. STAY ALERT! Watch what you are doing and use
common sense. Do not use the hoist when you are tired,
distracted or under the influence of drugs, alcohol or
medication causing diminished control.
Allowing the load to bear against the hook latch and/or hook tip
can result in loss of load.
TO AVOID INJURY:
Do not allow the load to bear against the hook latch and/or hook
tip. Apply load to hook bowl or saddle only.
