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.
Manual chain hoists must be used in a vertical position to provide a straight line pull from top hook
to bottom hook. The hoist must be positioned so that it does not contact the support members when
in use. When operating in limited areas suitable lifting attachments or slings must be used to
prevent the hoist body and hand chain from being obstructed.
Initial Operating Checks
CAUTION
• Ensure hoist top hook is properly installed on the support member and the hook latch is
engaged.
Operate the hoist with a test load (10% of rated capacity) by raising and lowering this load several
times. Verify the load brake operation by lowering the same load to check load does not slip when
lowering stops.
NOTICE
• Each time a load is lifted, the operation of the load brake should be checked by raising the
load slightly and stopping to ensure the brake will hold the load before proceeding to lift the
load.
Familiarize operators and people responsible for hoist installation and service with all applicable
specifications prior to placing the unit into service. All the requirements of these specifications,
including testing should be met before approving the hoist for operation.
OPERATION
The four most important aspects of hoist operation are:
1.
Follow all safety instructions when operating the hoist.
2.
Allow only people trained in safety and operation of this hoist to operate the hoist.
3.
Subject each hoist to a regular inspection and maintenance procedure.
4.
Be aware of the hoist capacity and weight of load at all times.
Always operate, inspect and maintain this hoist in accordance with any applicable safety codes and
regulations.
WARNING
• The hoist is not designed or suitable for lifting, lowering or moving persons. Never lift loads
over people.
Hoist Operation
When facing the hand chain side of the hoist: Rotate hand chain clockwise to raise load. Rotate
hand chain counterclockwise to lower load.
On 15 and 20 ton VL2 hoists, use two operators, one on each of the two hand chains. To keep the
load chain centered in the block assemblies, operate the hoist units simultaneously and at the same
speed. An equal amount of unloaded chain must be maintained under each hoist body.
