SAFETY PRECAUTIONS

Each UJC Lifting Motor is built in accordance with the
specifications contained herein and at the time of manufacture
complies with our interpretation of applicable sections of
*American Society of Mechanical Engineers Code (ASME)
B30.16 "Overhead Hoists," the National Electrical Code
(ANSI/NFPA 70) and the Occupational Safety and Health Act
(OSHA). Since OSHA states the National Electrical Code applies
to all electric lifting motors, installers are required to provide
current overload protection and grounding on the branch circuit
section in keeping with the code. Check each installation for
compliance with the application, operation and maintenance
sections of these articles.
*Copies of this standard can be obtained from ASME Order
Department, 22 Law Drive, Box 2300, Fairfield, NJ 07007-2300,
U.S.A.
Improper operation of a lifting motor can create a
potentially hazardous situation which, if not avoided,
could result in death or serious injury. To avoid such a
potentially hazardous situation, THE OPERATOR
SHALL:
1. NOT operate a damaged, malfunctioning or unusually
performing lifting motor.
2. NOT operate the lifting motor until you have thoroughly read
and understood the manufacturer's Operating and
Maintenance Instructions or Manuals.
3. NOT operate a lifting motor which has been modified without
the manufacturer's approval or without certification that it is in
conformity with ANSI/ASME B30 volumes.
4. NOT lift more than rated load for the lifting motor.
5. NOT use lifting motor with twisted, kinked, damaged, or worn
load chain.
6. NOT use the lifting motor to lift, support, or transport people.
7. NOT stand beneath a moving load! Do not move a load in
such a manner as to endanger personnel.
8. NOT operate a lifting motor unless all persons are and
remain clear of the supported load.
9. NOT operate unless load is centered under lifting motor.
10. NOT attempt to lengthen the load chain or repair damaged
load chain.
11. Protect the lifting motor's load chain from weld splatter or
other damaging contaminants.
12. NOT operate lifting motor when it is restricted from forming a
straight line from hook to hook in the direction of loading.
13. NOT use load chain as a sling, or wrap chain around load.
14. NOT apply the load to the tip of the hook or to the hook latch.
15. NOT apply load unless load chain is properly seated in the
chain sprocket(s).
16. NOT apply load if bearing prevents equal loading on all load
supporting chains.
17. NOT operate beyond the limits of the load chain travel.
18. NOT leave load supported by the lifting motor unattended
unless specific precautions have been taken.

19. NOT allow the load chain or hook to be used as an electrical
or welding ground.
20. NOT allow the load chain or hook to be touched by a live
welding electrode.
21. NOT remove or obscure the warnings on the lifting motor.
22. NOT operate a lifting motor on which the safety placards or
decals are missing or illegible.
23. NOT operate a lifting motor unless it has been securely
attached to a suitable support.
24. NOT operate a lifting motor unless load slings or other
approved single attachments are properly sized and seated in
the hook saddle.
25. Take up slack carefully - make sure load is balanced and load
holding action is secure before continuing.
26. Shut down a lifting motor that malfunctions or performs
unusually and report such malfunction.
27. Warn personnel of an approaching load.
Improper operation of a lifting motor can create a
potentially hazardous situation which, if not avoided,
could result in minor or moderate injury. To avoid such
a potentially hazardous situation, THE OPERATOR
SHALL:
1. Maintain firm footing or be otherwise secured when operating
the lifting motor.
2. Check brake function by tensioning the lifting motor prior to
each lift operation.
3. Use hook latches. Latches are to retain slings, chains, etc.
under slack conditions only.
4. Make sure the hook latches are closed and not supporting
any parts of the load.
5. Make sure the load is free to move and will clear all
obstructions.
6. Avoid swinging the load or hook.
7. Make sure hook travel is in the same direction as shown on
the controls.
8. Inspect the lifting motor regularly, replace damaged or worn
parts, and keep appropriate records of maintenance.
9. Use factory recommended parts when repairing the unit.
10. Lubricate load chain per lifting motor manufacturer's
recommendations.
11. NOT use the lifting motor's overload limiting clutch to measure
load.
12. NOT use limit switches as routine operating stops. They are
emergency devices only.
13. NOT allow your attention to be diverted from operating
the lifting motor.
14. NOT allow the lifting motor to be subjected to sharp contact
with other lifting motors, structures, or objects through misuse.
15. NOT adjust or repair the lifting motor unless qualified to
perform such adjustments or repairs.
