Maintenance
The lever hoist should be stored in a clean, dry
environment. Clean and oil the hoist before
storage.
Hoists that are installed out-of-doors should be
covered or brought inside when not in use.
Periodically apply a light coat of 30W oil to the
load chain. Also lubricate the safety latches and
the bearings in the hooks.
Allowable Limits for Load
Chain and Hooks
Load Chain
Carefully inspect the entire load chain. As
illustrated in Figure 8, measure five consecutive
links with calipers to find the length, Compare
the results with the table in Figure 8. Check
every three feet and especially where excessive
wear is indicated. Any load chain that shows
noticeable deformation or heat influence must
be replaced with a new one.
Never extend load chain by
welding a second piece to the original.
Hooks (Top and Bottom)
Replace the hook when the distance between
indicator points – “A” in Figure 9 – is wider than
the limits given in the table.
Never heat treat the hook or attach anything to
the hook by welding.
