HOIST SAFETY IS UP TO YOU...

–DO NOT APPLY MORE THAN RATED LOAD.

1 CHOOSE THE RIGHT HOIST FOR THE JOB...

Choose a Yale Lever Hoist with a capacity

or the job. Know the capacities of your

f
hoists and the weight of your loads. Then

atch them.

m

2 INSPECT

All hoists should be visually inspected

efore use, in addition to regular, periodic

b
maintenance inspections.

Inspect hoists for operational warning
notices and legibility.

Deficiencies should be noted and brought to
the attention of supervisors. Be sure
defective hoists are tagged and taken out of
service until repairs are made.

The application, the size and type of load,

he attachments to be used and the period

t
of use must also be taken into consideration

n selecting the right hoist for the job.

i

– DO NOT OPERATE DAMAGED OR MALFUNCTIONING UNIT.
– DO NOT OPERATE WITH TWISTED, KINKED OR DAMAGED

CHAIN.

nder no circumstances should you operate

U
a malfunctioning hoist.

Check chain for gouged, twisted, distorted
links and foreign material. Do not operate
hoists with twisted, kinked or damaged
chain links.

– DO NOT PULL AT AN ANGLE. BE SURE LEVER HOIST AND

LOAD ARE IN A STRAIGHT LINE.

– DO NOT USE UNLESS FRAME AND CHAIN FORM A

STRAIGHT LINE BETWEEN HOOKS.
– DO NOT USE IF FRAME IS IN CONTACT WITH ANY OBJECT.
– DO NOT USE LOAD CHAIN AS A SLING.
– DO NOT USE AN EXTENSION ON THE LEVER.

Remember the hoist was designed to ease

ur burden and carelessness not only

o
endangers the operator, but in many cases,

valuable load.

a

Load chain should be properly lubricated.

Hooks that are bent, worn or whose

penings are enlarged beyond normal

o
throat opening should not be used. If latch
does not engage throat opening of hook,
hoist should be taken out service.

Chains should be checked for deposits of
foreign material which may be carried into
the hoist mechanism.

Check brake for evidence of slippage under
load.

3 USE HOIST PROPERLY

Be sure the hoist is solidly held in
the uppermost part of the support
hook arc.

Be sure the hoist and load are in a
straight line. Do not use unless
frame and chain form a straight
line between hooks.

4 PRACTICE CAUTION ALWAYS

Do not lift co-workers with a Yale Lever
Hoist.

Make sure everyone is clear of the load
when you apply tension.

Do not remove or obscure operational
warning notices.

VIOLATION OF ANY OF THESE WARNINGS LISTED MAY RESULT SERIOUS PERSONAL INJURY TO THE

iii

OPERATOR OR NEARBY PERSONNEL BY RELEASED LOAD OR BROKEN HOIST COMPONENTS.

Be sure load is hooked securely.
Do not tip load the hook. Do not
load hook latch. Hook latch is to
prevent detachment of load under
slack chain conditions only.

– DO NOT LIFT PEOPLE OR LOADS OVER PEOPLE.

Do not operate with hoist frame
resting against any object. Apply
the load gently. Do not jerk it.

5 OPERATOR SERVICE

CLEANING: Lever Hoists should be kept
clean and free of dust, dirt, moisture, etc.,
which will in any way affect the operation or
safety of the equipment.
LUBRICATION: Chain should be properly
lubricated.
AFTER REPAIRS: Carefully operate the
hoist before returning it to full service.

Never use an extension on the
lever! You’re dangerously
overloading the hoist if you exceed
the rated lever pull or if you have
to use a lever extension to lift or
pull a load.

YALE REPAIR/REPLACEMENT POLICY

All Yale RS2 Lever Hoists are inspected and performance
tested prior to shipment. If any properly maintained hoist
develops a performance problem, due to a material or
workmanship defect, as verified by Yale, repair or
replacement of the unit will be made to the original
purchaser without charge. This repair/replacement policy
applies only to hoists installed, maintained and operated as
outlined in this manual, and specifically excludes hoists
subject to normal wear, abuse, improper installation,
improper or inadequate maintenance, hostile environmental
effects and unauthorized repairs/modifications.

load chain for long and dependable service.

Latchlok®Hooks

Latchlok hooks are available to replace the standard latch
type hooks. The unique design of the Latchlok hook assures
that it will stay locked until the operator releases it by
depressing the release button. It will not open accidentally­even if the load chain goes slack. Once opened, it can be
shut with one hand or by the weight of the load when it is
lifted. Latchlok hooks can be supplied with the hoist or it can
be provided in kit form for lever hoists already in service.

We reserve the right to change materials or design if, in our
opinion, such changes will improve our product. Abuse,
repair by an unauthorized person, or use of non-Yale
replacement parts voids the guarantee and could lead to
dangerous operation. For full Terms of Sale, see Sales
Order Acknowledgment. Also, refer to the back cover for
Limitations of Warranties, Remedies and Damages, and
Indemnification and Safe Operation.

WARNING

ALTERATIONS OR MODIFICATIONS OF EQUIPMENT AND USE OF
NON-YALE REPAIR PARTS CAN LEAD TO DANGEROUS
OPERATION AND INJURY.

TO AVOID INJURY:

• DO NOT ALTER OR MODIFY EQUIPMENT.

• DO USE ONLY YALE PROVIDED REPLACEMENT PARTS.

OPTIONS
Load Limiter

The Load Limited is a friction device that is designed and
factory calibrated to prevent lifting excessive overloads. An
excessive overload is indicated by lever movement without
corresponding movement of the lower hook or load when the
hoist is operated in the up direction. Should this occur,
operate the lever in the down direction to remove the
overload. Reducing the load to rated capacity or less will
automatically restore normal operation. The Load Limiter
can be ordered as part of a new lever hoist or in kit form that
can be added to units now in service.

®

Anchor Sling (for 3/4 and 1-1/2 ton units only)

Anchor Sling is an upper hook extender that simplifies
attachment when application or space limitation makes it
impossible to pull in a straight line from hook to hook. A
swiveling hook block is securely anchored to the housing
and the upper hook swivels through a full 360°. Anchor
Sling may be ordered as a feature of your new hoist or in kit
form for simple installation on units now in use.

INSTALLATION

UNPACKING

After removing the hoist from the carton, check it for damage
that may have occurred during shipment. If there is
damage, refer to the packing slip envelope for claims
procedure.

INSTALLATION

The RS2 Lever Hoist is designed for operation at ambient
temperatures of 0° to 100° F (-17° to 38° C). It can be used
in any position for pulling a load at an angle, horizontal
pulling or vertical lifting, provided it is rigged to pull in a
straight line from hook to hook and the frame is free to
swivel on the upper hook.
