Precautions
•
During lifting operations, do not stand under
the load.
•
Do not use any extension on the lever
handle. Do not use your foot to apply
pressure to the lever handle.
•
Prevent the chain from dragging over sharp
edges or corners. This will cause links to
weaken, bend, or break.
•
When connecting to a wire rope sling, the
lever hoist must be applied along a straight
line parallel to the surface on which it is
resting. See Figure 7.
•
When lifting loads, hook the load with slings.
Do not use the lever hoist chain as a
sling (Figure 8).
•
Both ends of a sling or rope must be
completely on the inside of the safety latch
before pulling or lifting the load. Do not put
one end on the inside of the latch and leave
the other end on the hook end outside the
latch.
Point Hooks
Point or "shipyard" hooks are available for your
JET lever hoist, in 1.6 ton and 3.2 ton load
sizes. They are available in both upper and
lower hook styles.
Point hooks are used in the metal and ship
building industries,
and are designed for
positioning steel plate and fixtures before
welding.
Overload Protection
Some models of the JLH Lever Hoist have
overload protection in the form of a slip clutch
(these are identified by "WO" in the model
number). The slip clutch is effective between
1.25 to 1.55 times the rated hoist capacity.
The slip clutch will allow the lever handle to
rotate without lifting the load, if the load is too
heavy for the hoist. The slip clutch has been
pre-adjusted at the factory and should not
require any adjustment by the user. If future
adjustment or repair to the slip clutch should
ever be needed, this must be done by qualified
personnel.
