Installation

Support for the hoist may be hook, clevis pin,
trolley, or beam clamp. Whatever method of
suspension is chosen, the support components
must be rated equal to, or greater than the
capacity of the lever hoist. Supporting structures
(such as I-Beams, etc.) should be installed by
properly licensed professional installers.

Pre-Operation Inspection

Inspecting the Load Chain

1. A chain stop must be attached to the
second-to-last link on the slack end of the
chain. See Figure 2.
Do not operate the hoist with
a twisted, kinked or damaged chain. Do not
splice the chain.
2. Check that the chain does not twist along its
length from hoist to hook. If twist is present
on units with multiple falls, the hook must be
passed back through the chain loop to
remove all twist in the chain.
3. Replace the chain if links are stretched too
long or seriously worn on the surface,
especially at the points where links contact
each other. See "Allowable Limits" on page
12 for measuring chain elongation.
4. Do not use a chain that is seriously rusted
or cracked.
5. Periodically apply a light coat of 30-weight
oil to the chain. This will create easier
operation and prolong the chain's life. For
optimum results, clean the chain with an
acid-free solution before oiling.
