HOIST SPECIFICATIONS
Coffing EMW series electric hoists are compact wire rope
hoists designed for a variety of light duty applications. The
EMW is constructed of lightweight aluminum housings to
provide strength and portability, weighing less than 25 lbs.
Other features include; thermally protected motors, swivel top
suspension, upper paddle limit switch to regulate load travel,
quick acting electromagnetic brake for positive load control and
thermal motor protection to prevent overheating. As a standard,
hooks are supplied with safety latches.
Coffing EMW series hoists are designed and tested in
accordance with the American Society of Mechanical
Engineers Code B30.16, “Safety Standard for Overhead
Hoists.” Coffing EMW series hoists are built in compliance with
UL, file number SA 5247. Made in U.S.A.
APPLICATION INFORMATION
This hoist is intended for lifting freely suspended (unguided)
loads weighing no more than 500 pounds. This hoist is not
intended for industrial or production applications requiring
continuous operation, it should only be used on an intermittent
basis. Coffing Hoists cannot be responsible for applications other
than those for which Coffing equipment is recommended. Prior
to installation and operation, we caution the user to review his
application for abnormal environmental or handling conditions
and to observe the applicable recommendations as follows:
ADVERSE ENVIRONMENTAL CONDITIONS
Do not use the hoist in uncovered outdoor locations, areas
containing flammable vapors, liquids, gases or any combustible
dusts or fibers. Refer to Article 500 of the National Electrical
Code. Do not use this hoist in highly corrosive, abrasive or wet
environments. Do not use this hoist in applications involving
extended exposure to ambient temperatures below -10°F or
above 130°F.
LIFTING OF HAZARDOUS LOADS
This hoist is not recommended for use in lifting or transporting
hazardous loads or materials which could cause widespread
damage if dropped. The lifting of loads which could explode or
create chemical or radioactive contamination if dropped
requires fail-safe redundant supporting devices which are not
incorporated into this hoist.
LIFTING OF GUIDED LOADS
This hoist is not recommended for use in the lifting of guided
loads, including dumbwaiters and elevators. Such applications
require additional protective devices which are not incorporated
into this hoist. For such applications, refer to the requirements
of applicable state and local codes, and the American National
Safety Code for elevators, dumbwaiters, escalators and moving
walks (ASME A17.1).
SAFETY INFORMATION
1. Follow all local electrical and safety codes, as well as the
National Electrical Code (NEC) and the Occupational
Safety and Health Act (OSHA) in the United States.
2. Hoist must be securely and adequately grounded.
3. Be careful when touching the exterior of an operating
motor; it may be hot enough to be painful or cause injury.
With modern motors this condition is normal if operated at
rated load and voltage (modern motors are built to operate
at higher temperatures).
4. Protect the power cable and control cable from coming in
contact with sharp objects.
5. Do not kink power cable and control cable and never allow
the cable to come in contact with oil, grease, hot surfaces,
or chemicals.
6. Make certain that the power source conforms to the
requirements of your equipment.
7. Inspect the unit daily before operating hoist.
8. Cluttered areas and benches invite accidents.
9. The operator should not engage in any practice which will
divert his attention while operating the hoist.
10. Before using the hoist, the operator should be certain that
all personnel are clear.
11. Do not operate hoist with loads exceeding its rated capacity.
12. Supporting frames or beams used as a hoist hanger must
have a greater load capacity than the hoist.
13. Do not attempt to operate hoist beyond normal maximum
lift range.
14. Align hoist for a straight line pull. Avoid side pull or end pull.
15. Do not operate hoist with twisted or damaged wire rope.
16. Do not operate a damaged or malfunctioning hoist until
necessary adjustments or repairs have been made.
17. Do not use hoist to lift people or to carry loads over people.
18. Do not leave a load suspended in the air unattended.
19. Always remove load before making repairs.
20. Do not remove or obscure capacity or warning decals.
Failure to comply with Safety Precautions outlined
throughout this manual can result in serious injuries
or death. Before using this hoist, each operator
should become thoroughly familiar with all warnings,
instructions and recommendations in this manual.
