SECTION I — INTRODUCTION
1-1 GENERAL INFORMATION
INSPECTION
This manual provides information for the safe operation and
maintenance of Coffing
®
JLC Series Hoists. All persons operating
or maintaining these hoists should be familiar with the information
contained herein. Adherence to the precautions, procedures, and
maintenance practices described should ensure long reliable
operation. Suggestions for improvements to this manual
are solicited.
To safeguard against the possibility of personal injury or property
damage, follow the recommendations and instructions of this
manual. This manual contains important information for the correct
installation, operation, and maintenance of this equipment. All
persons involved in the installation, operation, and maintenance of
this equipment should be thoroughly familiar with the contents of this
manual. Keep this manual for reference and further use
.
To avoid personal injury:
Do not use the equipment shown in this manual to lift, support, or
otherwise transport people, or to suspend unattended loads over
people.
1-2 SAFETY STANDARDS
All persons concerned with the installation, operation, inspection
and maintenance of these hoists are urged to read ASME B30.16.
That Standard contains valuable guidelines concerning practices
designed to minimize hazards associated with the use of overhead
hoisting equipment. ASME B30.16 also contains detailed procedures
for establishing hoist inspection and maintenance programs and can
be of significant assistance in maintaining compliance with OSHA
regulations.
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. Hoist
power cable is provided with an additional lead (green) for
grounding purposes.
Always disconnect power source before working on or near
a hoist or its connected load. If the power disconnect point
is out of sight, lock it in the open position and tag to prevent
unexpected application of power.
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 the 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 the 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 chain.
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
1-3 BASIC HOIST DATA
The basic hoist models covered by this manual are listed in
Table 1.
1-4 APPLICATION INFORMATION
This hoist is intended for general industrial use in the lifting and
transporting of freely suspended material loads within its rated
load. Prior to installation and operation, the user should review his
application for abnormal environmental or handling conditions and to
observe the applicable recommendations as follows:
a.
Adverse Environmental Conditions.
Do not use the hoist
in areas containing flammable vapors, liquids, gases or
any combustible dusts or fibers. Refer to Article 500 of
The National Electric 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.
b.
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 Ioads which could explode or create
chemical or radioactive contamination if dropped requires
fail-safe redundant supporting devices which are not
incorporated into this hoist.
c.
Lifting of Guided Loads.
This hoist must not be used in the
lifting of guided loads, including dumbwaiters, non-riding
elevators and elevators. Such applications require additional
protective devices which are not incorporated into this
hoist. Refer to your state and local regulations governing
and the American National Safety Code for elevators,
dumbwaiters, escalators and moving walks (ASME A17.1).
1-5 WARRANTY
Every hoist is thoroughly inspected and tested prior to shipment
from the factory. Should any problems develop, return the complete
hoist prepaid to your nearest Coffing Authorized Warranty Repair
Station. If inspection reveals that the problem is caused by defective
workmanship or material, repairs will be made without charge and
the hoist will be returned, transportation prepaid.
This warranty does not apply where: (1) deterioration is caused by
normal wear, abuse, improper or inadequate power supply, eccentric
or side loading, overloading, chemical or abrasive actions, improper
maintenance or excessive heat; (2) problems resulted from repairs,
modifications or alterations made by persons other than factory
or Coffing Authorized Warranty Repair Station personnel; (3) the
hoist has been abused or damaged as a result of an accident; (4)
repair parts or accessories other than those supplied by Coffing are
used on the hoist. Equipment and accessories not of the seller's
manufacture are warranted only to the extent that they are warranted
by the manufacturer. EXCEPT AS STATED HEREIN, COFFING
MAKES NO OTHER WARRANTIES, EXPRESS OR IMPLIED,
INCLUDING WARRANTIES OF MERCHANTABILITY AND FITNESS
FOR A PARTICULAR PURPOSE.
