3. Take up a slack load chain carefully and start the load
easily to avoid shock and jerking of the hoist load
chain. If there is any evidence of overloading,
immediately lower the load and remove the excess
load.
4. Do not allow the load to swing or twist while hoisting.
5. Do not allow the load to bear against the hook latch.
HOIST WITH PLAIN TROLLEY
This unit should be moved by pushing on the suspended load or
by pulling the empty hook.
HOIST WITH GEARED TROLLEY
This unit should be moved by means of the trolley hand
chain. Pull on the chain farthest from end toward which
the unit is to travel.
HOIST WITH MOTOR DRIVEN TROLLEY
This unit should be moved by operating the controls
located on the upper block of the pendant. Anticipate
the stopping point and allow trolley to coast to a smooth
stop. Reversing or “plugging” to stop the trolley causes sway-
ing of load.
SAFETY PROCEDURES
For safety precautions and a list of Do’s and Do Not’s for
safe operation of hoists, refer to page ii.
1. When preparing to lift a load, be sure that attach-
ments to the hook are firmly seated in the hook sad-
dle. Avoid off center loading of any kind, especially
loading on the tip of the hook.
2. When lifting, raise load only enough to clear the
floor or support and check to be sure that the
attachments to the hook and load are firmly seated.
Continue lift only after you are assured the load is
free of all obstructions.
3. Do not load hoist beyond the rated load shown on
hoist identification plate and capacity labels.
Overload can cause immediate failure of some load-
carrying part or create a defect causing subsequent
failure at less than rated load. When in doubt, use
the next larger capacity of XL Hoist.
4. Do not use this or any other overhead materials han-
dling equipment for lifting persons.
5. Stand clear of all loads and avoid moving a load over
the heads of other personnel. Warn personnel of
your intention to move a load in their area.
6. Do not leave load suspended in air unattended.
7. Permit only qualified personnel to operate unit.
8. Do not wrap the load chain around the load and
hook onto itself as a choker chain.
Doing this will result in:
a. The loss of the swivel effect of the hook which
could mean twisted chain and a jammed lift
wheel.
b. The chain could be damaged at the hook.
9. On double and triple reeved hoists, check for twists
in the load chain. A twist can occur if the lower
hook block has been capsized between the strands
of chain. Reverse the capsize to remove the twist.
10. Do not allow the load to bear against the hook
latch. The latch is to help maintain the hook in posi-
tion while the chain is slack before taking up slack chain.
11. Take up a slack load chain carefully and start load eas-
ily to avoid shock and jerking of hoist load chain. If
there is any evidence of overloading, immediately
lower the load and remove the excess load.
12. Do not allow the load to swing or twist while hoisting.
13. STAY ALERT! Watch what you are doing and use
common sense. Do not use the hoist when you are
tired, distracted or under the influence of drugs,
alcohol or medication causing diminished control.
INSPECTION
To maintain continuous and satisfactory operation, a reg-
ular inspection procedure must be initiated to replace
worn or damaged parts before they become unsafe.
Inspection intervals must be determined by the individ-
ual application and are based on the type of service to
which the hoist will be subjected and degree of exposure
to wear, deterioration or malfunction of the critical com-
ponents.
The type of service to which the hoist is subjected can be
classified as “Normal,” “Heavy,” or “Severe.”
Normal Service: Involves operation with randomly distrib-
uted loads within rated load limit, or uniform loads less
than 65 percent of rated load for not more than 25 per-
cent of the time.
Heavy Service: Involves operating the hoist within rated
load limit which exceeds normal service.
Severe Service: Normal or heavy service with abnormal
operating conditions.
Two classes of inspection—
Frequent and Periodic
—
must be performed.
FREQUENT INSPECTIONS:
These inspections are visual
examinations by the operator or other designated person-
nel. Records of such inspections are not required. The fre-
quent inspections are to be performed monthly for normal
service, weekly to monthly for heavy service, and daily to
weekly for severe service, and they should include those
items listed in Table 3.
PERIODIC INSPECTIONS:
These inspections are visual
inspections of external conditions by an appointed person.

WARNING
Allowing the load to bear against the hook latch
and/or hook tip can result in loss of load.
TO AVOID INJURY:
Do not allow the load to bear against the hook latch
and/or hook tip. Apply load to hook bowl or saddle only.
