GENERAL INFORMATION
SPECIFICATIONS
Yale LH2 Hand Hoists
The Yale LH2 Hand Hoist is a highly versatile
tool that can be used to lift loads. The hoist has
aluminum frame, handwheel, handwheel cover
and gear cover to provide dependable strength
at minimum weight. The internal gears are made
of high grade, heat treated steel. Shielded ball
bearings are used at each rotating point in the
mechanism. Latch type, heat treated, forged steel
upper and lower hooks are standard. The load chain
is strong and durable Hoistaloy®. A pawl and ratchet,
dry-operating, Weston-type friction brake supplies
very positive load control and will suspend the load
at any point. A Load Limiter is provided on every unit.
As a result, the application of an excessive overload
disengages the driving handwheel and prevents
hoisting. Note that the Load Limiter is not intended
for use as a scaling device. Removal of the excess
load automatically restores normal hoisting action
(see Figure 1 for specifications of available models).
Yale Low Headroom Trolley Hoists
The Yale Low Headroom Trolley Hoists (Figure 2, page 2)
are a combination of the Yale Hand Hoist built
integral with a rugged trolley to provide better head-
room than that obtained with the standard hoist and
trolley. The basic hoist is similar to the Yale LH2 Hand
Hoist except the frame, aluminum on the 1/2 through
3 ton units and cast iron on the 4 through 6 ton units,
which is designed to provide low headroom and
attachment to the trolley. The trolley has a rugged
frame, cast iron on the 1/2 through 1 ton units, and
steel plates on the 1-1/2 through 6 ton units. Crowned
tread, flanged trackwheels are provided to minimize
rolling friction. Hardened, pressed steel ball bearing
wheels are used on the 1/2 and 1 ton units. Hardened,
cast iron wheels with Timken bearings are used on the
1-1/2 through 6 ton units. Trolleys are adjustable for
operation on various American standard beams and
the 1-1/2 through 6 ton units are available in a geared
type trolley.

UNPACKING INFORMATION
After removing the hoist from the carton, check to
be sure there has been no damage in shipment.
Before cutting the cord ties on multiple-reeved
units, be sure that all strands of chain are straight
with no twist (due to a capsized hook block). If
length of lift is to be modified, follow disassembly
and assembly instructions for correct procedure.
OPERATING INSTRUCTIONS
After mounting and before placing in service,
check the hoist for proper operation. On multi-
reeved units, be sure that all strands of chain are
straight with no twist (due to a capsized hook
block).
The Yale Hand Hoist must always be rigged to lift
in a straight line from hook to hook (see Figure 4).
The hoist must always be free to swivel on the
upper hook. Under no condition should the hoist
be allowed to bear on any support when in use as
this would cause bending of the hook or frame
and damage the unit.
HOOKS
Type of hooks supplied on the Yale Hoists are shown
in Figure 3.
YALE REPAIR/REPLACEMENT POLICY
All Yale LH2 Hand Hoists and Low Headroom Trolley
Hoists are thoroughly inspected and performance
tested prior to shipment. If any properly maintained
Yale Hoist develops a performance problem due to a
material or workmanship defect, as verified by Yale or
an authorized service station, repair or replacement
of the unit will be made to the original purchaser
without charge. This repair/replacement policy applies
only to Yale Hoists installed, maintained and operated
as outlined in this manual, and specifically excludes
parts subject to normal wear, abuse, improper instal-
lation, improper or inadequate maintenance, hostile
environmental effects, and unauthorized repairs/
modifications.
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 Acknowledgement. Also, refer to
the back cover for Limitations of Warranties, Remedies
and Damages and, Indemnification and Safe Operation.

TROLLEY INSTALLATION
Operating the trolley hoist on a beam that has no rail
stops may allow the trolley hoist to fall off the end of
the beam.
To Avoid Injury:
Install rail stops at each end of the beam on which
the trolley hoist is to operate.
The railstops must be positioned so as to not exert
impact force on the hoist portion of the unit or the
trolley wheels. They must contact the ends of the
trolley side frames.
Due to the variations in beam flange widths, it is sug-
gested that the beam flange width be measured to
determine the exact distribution of spacer washers.
The distance between trackwheel flanges (dimension
“X”) should be 1/8 to 3/16 inch greater than the
beam flange width for straight runway beams, and
3/16 to 1/4 inch greater than the beam flange width
if runway system includes sharp curves. Also, the use
of other than Yale supplied washers may result in
trackwheel to beam flange variations and thus Figure
5 will not apply.
Assemble the trolley on the beam by sliding one side
out far enough to allow the wheels to clear the
beam flange. Draw side frames together and tighten
nuts securely (do not over tighten) and then install
the cotter pins.
If washer spacing recommendations are not followed,
trolley hoist may fall from beam.
To Avoid Injury:
Measure the actual beam flange on which the trolley
hoist is to operate and use figure 5 to determine the
arrangement of the spacer washers for that flange
width.
Immediately after installation, operate trolley with a
capacity load over the entire length of runway or
monorail system to be sure that all adjustments and
operations are satisfactory.
When applying a load, it should be directly under
the trolley. Avoid off center loading of any kind.
Side loading may spread trolley side frames.
On systems with curves, the edges of the rail at the
curved sections should be lightly lubricated with
grease.
An excessively worn beam flange may fail and
allow the trolley hoist to fall from the beam.
To Avoid Injury:
Periodically inspect the beam flange for wear.
Replace beam if flange is worn.

OPERATING AND SAFETY PROCEDURES
For safety precautions and a list of do’s and do not’s
for safe operation of hoists, refer to page ii.
The Yale LH2 Hand Hoist (see Figure 6) must always
be rigged to lift in a straight line from hook to
hook. The hoist must always be free to swivel on
the upper hook. Under no condition should the
hoist frame or hanger be allowed to bear on any
support when in use as this would cause bending of
the hook or frame and damage the unit.
When preparing to lift or move a load, be sure that
the attachments to both hooks are firmly seated in
the saddles of the hooks. Avoid off center loading
of any kind especially loading on the point of the
hook.
When lifting, raise the load only enough to clear
the floor or support, and check to be sure brake will
hold load and that attachments to the load are
firmly seated. Continue the lift only after you are
assured the load is free of all obstructions.
Do not load beyond the rated capacity of the hoist.
Overloading can cause immediate failure of some
load carrying part or result in damage causing fail-
ure at less than rated capacity. When in doubt, use
the next larger capacity of Yale LH2 Hoist.
Do not wrap load chain around the load or bring
the load in contact with the hoist. Doing this will
result in the loss of the swivel effect of the hook
which could cause twisted chain and a jammed lift-
wheel. The chain could be damaged at the hook.
Rail stops must be installed for all trolleys operating
on open end beams. These stops must be positioned
to exert impact force on the trolley side frames only.
Do not use this or any other overhead materials
handling equipment for lifting persons.
Stand clear of all loads and avoid moving a load over
the heads of any people. Warn any people of your
intention to move a load in their area.
Do not leave the load suspended in the air unattended.
Do not lower the hook to a point where the chain
becomes taut between the liftwheel and loose end
screw. (See Troubleshooting, Item 5C).
The Yale LH2 Hand Hoist and Yale Low Headroom
Trolley Hoist have been designed for manual
operation only.
Power operation may result in structural damage or
premature wear that may cause a part to break and
allow the load to fall.
To Avoid Injury:
Operate Yale LH2 Hand and Trolley Hoists using
hand power only.
To maintain continuous and satisfactory operation, a
regular inspection procedure must be initiated to
replace worn or damaged parts before they become
unsafe. Inspection intervals must be determined by
the individual application and are based on the type
of service to which your hoist will be subjected and
the degree of exposure to wear, deterioration or
malfunction of the critical components.
The type of service to which the hoist is subjected
can be classified as “Normal”, “Heavy” and “Severe”.
Normal Service: involves operation with randomly
distributed loads within the rated load limit, or
uniform loads less than 65% of rated load for not
more then 25% of the time.
Heavy Service: involves operating the hoist within
rated load limit which exceeds normal service.
Severe Service: is normal or heavy service with
abnormal operating conditions.
Following are the recommended, minimum intervals
of inspection. When the unit is subjected to extra
heavy usage or dusty, gritty, moist, or other adverse
atmospheric conditions, shorter time intervals must
be assigned. During the Periodic Inspection, inspection
must be made of all parts for unusual wear, corrosion
effect or damage in addition to those specifically
mentioned.
Before working on the hoist, review the disassembly
and assembly information on pages 8 through 13.

WARNING
For more information contact: Sievert Crane and Hoist, [phone], [email protected], www.sievertcrane.com

Minimum Inspection Schedule
Frequent Inspections: These inspections are
visual examinations by the operator or other des-
ignated personnel. Records of such inspections are
not required. The frequent inspections are to be
performed monthly for normal service, weekly to
monthly for heavy service, and daily to weekly for
severe service and they should include those items
listed in Table 1.
Periodic Inspections: These inspections are visu-
al inspections of external conditions by an appoint-
ed person. Records of periodic inspections are to
be kept to provide the basis for continuing evalua-
tion of the condition of the hoist.
Periodic inspections are to be performed yearly for
normal service, semi-annually for heavy service and
quarterly for severe service and they are to include
those items listed in Table 2.
Any parts that are deemed unserviceable are to be
replaced with new parts before the unit is returned
to service. It is very important that the unserviceable
parts be destroyed and properly disposed of to
prevent their possible future use as a repair item.

Any deficiencies are to be corrected before returning the
hoist to service. Operating a hoist with worn or damaged
parts or a malfunctioning hoist may result in serious
personal injury to the operator, nearby personnel and/or
property damage.
Also, the external conditions may show the need for dis-
assembly to permit a more detailed inspection which, in
turn, may require the use of nondestructive type testing.
PREVENTIVE MAINTENANCE
In addition to the above inspection procedure, a preventive
maintenance program should be established to prolong
the useful life of the hoist and maintain its reliability and
continued safe use. The program should include the
periodic inspections with particular attention being paid
to the lubrication of various components using the
recommended lubricants.

HOOK INSPECTION
Hooks damaged from chemicals, deformation or
cracks, or that have more than a 10 degree twist
from the plane of the unbent hook or excessive
opening or seat wear must be replaced.
Also, on latch type hooks, hooks that are opened
and allow the latch to disengage the tip, must be
replaced.
Any hook that is twisted or has excessive throat
opening indicates abuse or overloading of the unit.
Other load sustaining components of the hoist
should be inspected for damage.
Check to assure latch is not damaged or bent and
that it operates properly with sufficient spring
pressure to keep the latch tightly against the tip of
the hook and allow the latch to spring back to the
tip when released. If the latch does not operate
properly, it should be replaced.
The charts below (Figures 7 and 8) should be used
to determine when the hook must be replaced.
LOAD CHAIN
Cleaning and Inspection
First clean the load chain with a non-acid or non-caustic
type solvent, then slack the chain and make a link-by-link
inspection for nicks, gouges, twisted links and excessive
wear or stretching. Worn chain should be gaged through-
out its entire length and replaced if beyond serviceable
limits. Also, these chains are specially heat treated and
hardened and should never be repaired.
Using other than a Yale supplied load chain may
cause the chain to jam and this, in turn may break
the chain and allow the load to drop.
To Avoid Injury:
Use only Hoistaloy®load chain in the Yale LH2 Hand
and Low Headroom Trolley Hoists.
Gaging Load Chain Wear
To determine if the load chain should be continued in
service, check gage lengths as indicated in Figure 9.
Chain worn beyond length indicated, nicked, gouged
or twisted should be replaced before returning the
hoist to service. Chain should be clean, free of twists
and pulled taut before measuring. To aid in checking
gage length, Yale can provide a chain gage. This can
be obtained by ordering chain gage part number 3191.
Worn load chain may break suddenly without visual
deformation.
To Avoid Injury:
Never use load chain for any other purposes such as

Note that worn chain can be an indication of
worn hoist components. For this reason, the
hoists chain guide, hook blocks and liftwheel
should be examined for wear and replaced as
necessary when replacing worn chain.
The proper installation of the load chain is
covered in the section on reeving, (see Pages
10 through 13.
HAND CHAIN
Hand chain should be cleaned, inspected and gaged in
the same manner as load chain. It is not hardened and
can be cut with a hacksaw.
The hoist hand chain contains one unwelded connecting
link. This link can be placed in a vise and twisted open
to facilitate changing chain length. Additional connecting
links can be made by cutting the weld side of a standard
link.
Care must be taken to assure that there is no twist in
the hand chain loop.
MAINTENANCE
LUBRICATION
The lubricants used in and recommended for the
Yale LH2 Hand and Trolley Hoists may contain haz-
ardous materials that mandate specific handling and
disposal procedures.
To Avoid Contact and Contamination:
Handle and dispose of lubricants only as directed
in applicable material safety data sheets and in
accordance with applicable local, state and federal
regulations.
NOTE: To assure extra long life and top per-
formance, be sure to lubricate the various
parts of the Yale Hoist using the lubricants
specified below. If desired, these lubricants
may be purchased from Yale. Refer to page 18
for information on ordering the lubricants.
LOAD CHAIN
Lubricate chain with a light coat of Lubriplate®, Bar
and Chain Oil (Fiske Bros. Refining Co.) or equal
lubricant. Be sure the lubricant reaches the bearing
surface between the links. Remove excess oil from
the chain.
Used motor oils contain known carcinogenic materials.
To Avoid Health Problems:
Never use used motor oils as a chain lubricant.
Only use Lubriplate®Bar and Chain Oil 10-R as a
lubricant for the load chain.
The hoist normally requires no additional lubri-
cation except when a unit has been disassem-
bled for cleaning or repairs (see page 8).
NOTE: The brake is designed to operate dry.
Do not use any grease or lubricant on the
braking surfaces. On reassembly when
lubricating parts adjacent to the brake, do
not use an excessive amount of lubricant
which could seep onto the brake surfaces.
Load Limiter. Place a small amount of stay-put lubri-
cant such as Moly-Duolube Style 69 (Hercules Packing
Co.) on load limiter handwheel threads. Do not allow
lubricant to contact brake surfaces or friction surfaces
of load limiter.
Gears. Lubricate the gears with Texaco Novatex #2 or
equal, 3 ounces for the 1/4-1 ton units and 4 ounces for
the 1-1/2-10 ton units. Spread some grease on gear
teeth, place the balance in gear housing in contact
with the gears.
Geared Trolleys. Upon installation and once a month
lubricate trackwheel gears and pinion with Texaco
Novatex #2 or an equivalent heavy cup grease or
graphite grease.
Brake. The brake parts should be thoroughly cleaned
(by wiping with a cloth - not by washing with a
solvent) and inspected for wear or scoring. The friction
surfaces of the handwheel, ratchet and friction hub
must be smooth and free from any score marks. When
friction washers are visibly worn to a thickness of 0.100
inches or less, scored excessively, or coated with foreign
matter, replace with new washers. Keep washers and
brake surfaces clean and dry.
RECOMMENDED SPARE PARTS. Refer to page 19 for
the list of recommended spare parts.
EXTERIOR FINISH
The exterior surfaces of the hoist and trolleys have a
durable, scratch resistant baked powder coating.
Normally, the exterior surfaces can be cleaned by
wiping with a cloth. However, if the finish is damaged,
compatible touch-up paint can be purchased from Yale.
Refer to page 18 for information on ordering
the paint.

DISASSEMBLY
Care must be exercised in disassembly of the
hoist to assure proper assembly. The following
pins have tapered splines and can only be
removed by tapping on the end opposite the
splined grooves.
Lower Hook Block, Upper Hook Collar
and Dead End Pins
When removing or installing the Lower Hook
Block Pins (646-29J or 646-129J) on the 1/4 thru
2 ton units, the Upper Collar Pins (646-1E or 646-
101E) on the 1/4 thru 2 ton units and the Dead
End Pins (646-259) on the 3, 4, 8 and 10 ton units,
care must be taken so as to prevent damaging
the pin and/or the part into which the pin is driven.
These pins are tapered groove pins and as a
result, they can only be removed and installed in
one direction. To remove the pin, a drift and
hammer (or slow acting press) are required. For
the lower hook block pins, a V-block will also be
necessary. The drift should be the same diameter
as the pin (5/16” diameter for the 1/4 thru 1 ton
units and 7/16” diameter for the 1-1/2, 2, 3, 4, 8
and 10 ton units) and it should be placed on the
small end of the pin. The small end of the pin is
the end opposite the end on which the 3 grooves
are visible. Place the drift on the small end of
the pin and drive the pin out using a hammer or
slow acting press. When removing the pin from
the lower hook block, the hook block should be
placed in a V-block.
To re-install the pin, the parts must be arranged
the same as they were when the pin was
removed. To do this, use the small end of the pin
as a gauge. After it is determined which end of
the hole is the largest, arrange the parts so that
the large holes are aligned and insert the small
end of the pin into the hole. Push the pin in by
hand until it stops and then use a hammer or
slow acting press to drive the pin into position
so that the end of the pin is flush with the
outside surface of the hook block body, upper
hook collar or hoist hanger.
Using other than the Yale supplied, high
strength pins may cause the pin to break and
allow the hoist and/or load to fall.
To Avoid Injury:
Use only the special high strength pin as
supplied by Yale.
ASSEMBLY
Consideration must be given to the following
when assembling the hoist:
Brake. Assemble the brake components per Figure 10.
Check the ratchet to be sure the bushing is flush with
or below the surface on both sides. When installed, the
teeth must face as shown in Figure 10 and engage the
pawl. Do not lubricate. The brake operates dry.
FIGURE 10. Brake Assembly
Load Limiter. Place a small amount of stay-put lubri-
cant such as Moly-Duolube Style 69 (Hercules Packing
Co.) on Load Limiter handwheel threads to lubricate
the friction hub at assembly. Do not allow lubricant to
contact brake surfaces or friction surfaces of Load
Limiter.
The handwheel shaft nut and washer must tighten
against the friction hub, not the Load Limiter (see
Figure 11). the Load Limiter must be free to revolve
slightly on the friction hub. If the Load Limiter is
disassembled, it must be recalibrated before being
placed in service.
FIGURE 11. Load Limiter Assembly

Components must be assembled in the order
shown with the friction washers seated on the
handwheel projections. Handwheel, spring wash-
er, lockwasher and nut must face as shown.
Tighten the adjuster nut hand tight, then turn
clockwise one notch. A NOTCH is turning the nut
sufficient to bring a slot in the nut and a tang of
the lockwasher in line. The next notch brings a
different slot and tang in line.
Do not bend the lockwasher tang at this time.
The Load Limiter
must be calibrated
after assembly.
Calibration. Install
the Load Limiter
(see Figure 11) and
hand chain but not
the handwheel
cover. Mount the
hoist where a load
greater than that
shown in Table 3
can be applied.
Connect a straight
spring scale to the
hand chain so that
a pull can be
applied in the
hoisting direction.

With the load chain taut, apply a steady pull to
the scale to slip the handwheel one revolution
(approx. 2 ft. of hand chain travel - see Figure
12). Record several pull values and obtain the
average. Disregard the initial “break free” pull -
use only values obtained after the handwheel has
started to slip. When properly adjusted, the
average pull should be as indicated in Table 3.
If the average pull is low, turn the adjuster nut
one notch clockwise and repeat the pull opera-
tion. Do this until the correct value is obtained,
then bend the lockwasher tang into the locknut
notch. Load Limiter is now ready for service.
If the handwheel does not slip or the pull is too
high, back off the adjuster nut and start over.
After the proper calibration is obtained, install
the handwheel cover.
Bearing Retainer Screws. Whenever the bearing
retainer screws have been removed and replaced,
they must be locked in place by prick punching the
head (see Figure 13). Always use new spots for locking.
FIGURE 13. Bearing Retainer Screw
Hoist Hanger. The Hoist Hanger and Hoist are not
bolted together to form a rigid unit but can move
relative to each other.
When installing a new hoist hanger screw (646-234A),
tighten the screw firmly and back off one flat (1/6
turn). Then:
3 and 4 ton hoists: Install hoist hanger set screw
(646-233B).
5 to 10 ton hoists: Using the hole in the end of the
hoist hanger as a guide, drill a 0.250 to 0.256 inch
diameter hole through the hoist hanger screw and the
other side of the hoist hanger. Complete the assembly
by driving the hoist hanger screw pin (646-234D) into
hole so that the end of the pin is flush with the end of
the hoist hanger (see Figure 14).

Hooks. Both upper and lower hooks must be free
to swivel. Those that are held by nuts must be
adjusted to provide 1/32” clearance as shown in
Figure 15 before the hook nut pin is inserted.
FIGURE 15. Hook Mounting
Lower Hook Thrust Bearings. The 1/4 thru 6
ton lower hook thrust bearings are mounted with
the outer shell down (see Figure 15).
Hand Chain. Hand chain must have an odd
number of links.
Join the ends with the “hand chain connecting
link”(646-45) so that there is no twist in the
completed chain loop. The connecting link must
be completely closed so that it will seat in the
handwheel the same as the welded links.
REEVING
Improper installation (reeving) of the load
chain can result in a dropped load.
To Avoid Injury:
Reeve and attach the ends of the load in
accordance with the following instructions.
1/4-1/2-1 Ton Hoists
Attach approximately 20 inches of wire to the
loose end of the load chain. Feed the wire around
the liftwheel as shown in Figure 16 until the first
link starts over it. The first and third links must
stand on edge with the weld away from the lift-
wheel. After the chain has been started, pull the
hand chain or turn the handwheel in the hoisting
direction until about 2 feet of load chain has
passed over the liftwheel.
If it becomes difficult to pull the hand chain in
the hoisting direction, pull it in the lowering
direction to release the load chain. Start over. This
will prevent the load chain from being jammed
between the liftwheel and frame.
Remove the wire and attach the loose end of
chain to the hoist using the loose end screw and
washer (see Figure 16). The chain must not be
twisted between the liftwheel and loose end screw.

end of the load chain. Feed the wire around the lift-
wheel as shown in Figure 17 until the first link starts
over it. The first link must lay flat on the liftwheel.
The second link must stand on edge with the weld
away from the liftwheel. After the chain has been
started, pull the hand chain or turn the handwheel in
the hoisting direction until about 2 feet of load chain
has passed over the liftwheel.
If it become difficult to pull the hand chain in the
hoisting direction, pull it in the lowering direction to

Cutting Chains
Hoistaloy®load chain is hardened for wear
resistance and is difficult to cut. However, the
following methods are recommended when
cutting a length of new chain from stock or cutting
off a length of worn chain.
FIGURE 22. Cutting Chain by Nicking
(1) Use a grinder and nick the link on both sides
(see Figure 22), then secure the link in a vise
and break off with a hammer.
(2) Use a 7 inch minimum diameter by 1/8 thick
abrasive wheel (of type recommended by wheel
supplier) that will clear adjacent links.
(3) Chain may also be cut using a bolt cutter (see
Figure 23) similar to the H.K. Porter No. 0590MTC
with special cutter jaws for cutting hardened
chain (1 inch long cutting edge).
FIGURE 23. Cutting Chain with a Bolt Cutter
Cutting chain can produce flying particle.
To Avoid Injury:
• Wear eye protection.
• Provide a shield, such as a heavy rag, over the chain
to prevent flying particles.
TESTING
Prior to initial use, all altered or repaired hoists or used
hoists that have not been operated for the previous 12
months shall be tested by the user for proper opera-
tion.
Test the unit first in the unloaded state and then with
a light load of 50 pounds times the number load sup-
porting parts of load chain to be sure it operates prop-
erly and the brake holds the load when the hand chain
is released; then test with a load of *125% of rated
capacity by or under the direction of an appointed per-
son and a written report prepared for record purposes.
After this test, the function of the Load Limiter is to be
tested (see Table 3, page 9).
*If load limiter prevents lifting of a load of 125% of rated capacity, reduce load
to rated capacity.
