3.2 Chain
3.2.1 The quantity and location of the chain components including chain springs and stoppers depends on
the hoist model and capacity. Never operate the hoist with incorrect, missing or damaged chain
components. Refer to the hoist's nameplate, Table 3-2, and Figure 3-2 and ensure that all chain
components are in the correct location and properly installed.
3.2.2 When the hoist is used without a chain container, the free end of the chain is attached to the hoist body
as shown in Figure 3-2. Connect the “no load” end of the chain to Chain Guide A and the pre-installed
socket bolt and lock nut. Make sure the chain remains free of twists and the chain Stopper is installed
on the correct link. Refer to Table 3-2 for proper placement of Stopper.

3.2.3 When the optional canvas chain container(s) is used, unfold it fully and install it on the hoist body(ies)
as shown in Figure 3-3. 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(s), feed the chain into the chain container(s) beginning with the free end. Take care to avoid
twisting or tangling the chain. NEVER put all the chain into the container(s) at once. Lumped or
twisted chain may 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.
