No Load Operational Checks

ü Check the hoist motor brake function.
ü Run the empty hook block up or down to check that the hook drift does not exceed more than
1 inch (25mm). If so, adjust the brake as described in Section 4, Operation/Maintenance.
ü Run the empty hook block down to check that the slack fall stop on the free end of the chain
(inside the chain container) makes proper contact with the buffer or the limit switch, if
furnished in place of the buffer. If furnished, check that the limit switch functions correctly.
ü Run the empty hook block up to check that the load block makes proper contact with the
rubber buffer or the limit switch, if furnished in place of the buffer. If furnished, check that
the limit switch functions properly.
ü Run the empty hook block up and down several times while checking for proper tracking of
the load chain.

Torque Limiter

The electric chain hoist is equipped with a torque-limiting device to help protect against damage
from attempts to lift an over-capacity load. This device is not intended as a measuring device and
shall not be used as such. The device is adjusted at the factory for the rated load capacity of the
hoist. Sound operating practices shall be followed to avoid attempts to lift over-capacity loads.

Load/Run Test

While each complete hoist is load tested at the factory, the user should perform a full load test
after installation of the hoist and completion of no load operational tests.
Lift a near capacity load about 1 foot (30cm) above floor level and check that the brake holds the
load. Also, check the holding capability of the brake when lifting/lowering and stopping the load.
