Operation
Face the hand chain wheel side of the hoist.
Pulling the hand chain in clockwise direction will raise the load. Pulling the hand chain in
anticlockwise direction will lower the load.
On hoists with two chain block heads, use two operators, one on each of the two hand
chains. To keep the load chain centred in the block assemblies, operate the units simultaneously
and at the same speed. An equal amount of unloaded chain must be maintained under each
hoist body.
Stop operating in the lifting direction when the hook block contacts the hoist body, as noted by
the sudden increase in the hand chain pull or the tipping of the hook block.
The operator must ensure that the hoist is suspended in a manner that makes it possible to ope-
rate the unit without exposing himself or other personnel to danger by the unit itself, the suspen-
sion or the load.
When the unit is not in use, position the suspension (e.g. bottom block, load hook) above nor-
mal head height, if possible.
Do not allow load chain on hoists with two chain block heads to accumulate on one side (under
one hoist body). Excessive loading to load chain anchor may occur resulting in a falling load
which can cause death, injury or property damage.
The chain blocks fitted with the protected twin pawl quad cam brake system can be safely
used for "fleeting" and "cross-hauling" applications up to 45°. All such operations should
be carried out in accordance with manufacturer's instructions and fully risk assessed by a
competent person.
As well as following any industry or country specific guidance on chain blocks used at an
angle to the vertical, we recommend that before commencing an operation using multiple hoists
or involving the transfer of a load from one hoist to another, the following is adhered to:
• All the units that are to be used in such an operation must be of the same make and model and
have the same rated capacity.
