Attachment of Chain to Hoist Body – No Chain Container

3.2.3

When the optional canvas chain container is used, unfold it fully and install it on the hoist body as
shown in

Figure 3-5

. In this case the free end of the chain is not attached to the hoist body and the

chain stopper is installed on the third link from the free end. To place the chain into the chain container,
feed the chain into the chain container beginning with the free end. Take care to avoid twisting or
tangling the chain. NEVER put all the chain into the container at once. Lumped or twisted chain may:

§ Upper Limit Switch Only - jam against the hoist body activating the friction clutch and potentially

damaging the chain.

§ Upper and Lower Limit Switch (Optional) - activate the down limit switch and stop the hoist during

lowering.

3.2.4

CAUTION

Each chain container indicates the maximum length of the load chain that can be

stored in the container. The amount of chain the container must hold is equal to the lift on the hoist.
DO NOT use a chain container with a storage capacity less than the lift length on the hoist. If all of the
chain can not be stored in the container, the limit switch will not operate properly.
