SAFETY PRECAUTIONS

Each Coffing ELC Series Electric Chain Hoist 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 hoists, 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.

1.

NOT

operate a damaged, malfunctioning or unusually

performing hoist.

2.

NOT

operate the hoist until you have thoroughly read and

understood the manufacturer’s Operating and Maintenance
Instructions or Manuals.

3.

NOT

operate a hoist 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 hoist.

5.

NOT

use hoist with twisted, kinked, damaged, or worn load

chain.

6.

NOT

use the hoist to lift, support, or transport people.

7.

NOT

lift loads over people.

8.

NOT

operate a hoist unless all persons are and remain clear

of the supported load.

9.

NOT

operate unless load is centered under hoist.

10.

NOT

attempt to lengthen the load chain or repair damaged

load chain.

11. Protect the hoist’s load chain from weld splatter or other

damaging contaminants.

12.

NOT

operate hoist 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 hoist 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 hoist.

22.

NOT

operate a hoist on which the safety placards or decals

are missing or illegible.

23.

NOT

operate a hoist unless it has been securely attached to

a suitable support.

24.

NOT

operate a hoist 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 hoist that malfunctions or performs unusually

and report such malfunction.

27. Make sure hoist limit switches function properly.

28. Warn personnel of an approaching load.

1. Maintain firm footing or be otherwise secured when operating

the hoist.

2. Check brake function by tensioning the hoist 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 hoist regularly, replace damaged or worn parts,

and keep appropriate records of maintenance.

9. Use Coffing Hoists recommended parts when repairing the

unit.

10. Lubricate load chain per hoist manufacturer’s

recommendations.

11.

NOT

use the hoist’s overload limiting clutch to measure load.
