SAFETY RULES
Inspect the hoist for any sign of loose, broken or
malfunctioning parts. Any malfunctioning hoist should be
tagged as “out of order” and removed from service until the
defect is corrected.
a.
Do not overload the hoist.
b.
Do not exert more than the hand chain pull to lift rated
load by one operator (See Table 1). The hoist is designed
to lift its rated capacity when a reasonable force is
exerted. If effort appears to be excessive, recheck the
load and use a larger capacity hoist if necessary.
c.
Do not side load the hoist. Always pull in a straight line
between hooks. Side loading over a sharp corner may
fracture the hoist housing, load block or hook.
d.
Be sure there are no twists in the load chain and make
sure that load chain is free to move and will clear all
obstructions. On a multiple chained hoist it is possible for
the load block to be capsized or turned over one or more
times causing the chain to twist.
e.
Do not operate the hoist from an off balance position.
Operator should have firm footing or be otherwise secured
before operating the hoist.
f.
Before raising or pulling a load, always check to see that it
is held securely in the hook or sling chains, etc. Raise the
load only until the load chain is taut and then recheck the
rigging before continuing to raise the load.
g.
Make sure that the slings and other rigging have sufficient
capacity to support the load, and are in good condition.
h.
DO NOT STAND BENEATH A LOAD! Do not move a load
in such a manner as to endanger personnel.
i.
Do not leave the hoist under load for extended or
unattended periods unless specific precautions have been
taken to provide protection.
j.
Do not wrap the load chain around a load. USE A SLING!
k.
Do not TIP-LOAD any hook, as this will exert undue strain
in the hook, resulting in hook failure.
l.
The hoist is designed for manual operation by one person.
Do not attempt to operate hoist with other than the
manual power furnished by one person.
m. DO NOT USE HOIST TO LIFT, SUPPORT OR
OTHERWISE TRANSPORT HUMAN CARGO.
n.
The hand chain is equipped with a safety link. When the
safety link opens or deforms, stop at once and inspect for
the cause.
o.
Lifting a load with two hoists is not recommended. If
operation is unavoidable, hoist the load with utmost care,
keeping balance of the load.
p.
Never run the load chain out too far. When operating
beyond the range of lift, an excessive load that can cause
damage will be imposed on the hoist.
q.
Hoists are designed for lifting loads vertically and should
not be used for horizontal or angle hoisting.
r.
Extreme temperatures will lower the toughness of the
hoist. Loads should be hoisted or lowered very slowly and
carefully.
s.
The hoisting operation should never be done with the
bottom hook or load caught on a fixed object.
t.
Never use the chain or hook as a ground for welding.
u.
Use only genuine parts and chains supplied by the
authorized distributor.
HANDLING THE LOAD
ATTACHING THE LOAD
a.
The load should be attached to the hook by means of
slings or other appropriate devices. Never wrap the load
chain around a load.
b.
Be sure the load is supported in the saddle of the hook
and the latch is closed. Do not support a load on the tip of
the hook.
LIFTING THE LOAD
a.
Raise the load by pulling the right side hand chain. Lift the
load just clear of the floor. Check that slings are secure in
the hook, the load is well balanced, and the hoist brake is
holding the load. Lift the load to desired height, always
standing clear of the suspended load.
b.
Lower the load by pulling the left side hand chain. Pull
smoothly and slowly. Avoid “spinning” the hand chain.
c.
Never jam the hook block into the bottom of the hoist, or
run the hook down until the slack chain is pulled tight.
PREVENTIVE MAINTENANCE
Periodic inspection and lubrication is important to ensure long
and satisfactory operation of the hoist. The recommended
inspection intervals indicated in Table 2 are based on
intermittent operation. The user should reduce or extend his
inspection intervals based on usage and individual experience.
