Chain Block
Rated Load
Hand Chain Pull to
lift Rated Load Kg
Safety Procedures
1. The Chain Block must always be rigged to lift in a
straight line from hook to hook. The Chain Block
must always be free to swivel on theupper hook.
Under no conditions should the Chain Block 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 centre loading
of any kind especially loading on the tip of the
hook.Also observe that the chain hangs straight
(without twists) from Chain Block 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 the 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 Chain
Block. Rated capacity can be achieved with the
following hand chain pulls. 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. Overloading can
cause immediate failure of some load carrying
parts or result in damage causing failure at less
than the rated capacity.
Exceeding the rated capacity of the Chain Block may
cause load to fall.
To Avoid Injury
Do not exceed the hand chain pulls specified in safety
procedure 4.
5. Do not wrap load chain around the load or bring
the load in contact with the Chain Block. Doing
this will result in the loss of the swivel effect of the
hook which could mean twisted chain and jammed
liftwheel. The chain could be damaged at the hook.
6. Stand clear of all loads and avoid moving 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
pin.
9. Do not run the lower hook block into the Chain
Block frame. Frame and/or chain guide damage
may result.
10. The Chain Block has been designed for manual
operation only.
Special Note for User:
Twisting of Chain
3 tonne Chain Blocks and above have multiple falls of
load chain.
THE LOAD CHAIN MUST BE INSPECTED
FOR TWISTS PRIOR TO EACH LIFT.
If the Chain Block
bottom hook has looped through the multi fall of load
chain this can create a twist in the load chain that can
damage the Chain Block and cause injury.
