SECTION I - GENERAL DESCRIPTION

Figure 1-1. Views of Various Air Hoist Models

12021C

1-1. GENERAL. BUDGIT Air Hoists are precision built chain

type hoists which are built in three rated loads, 1/4, 1/2, and 1

ton. Each size is available in pull cord control and pendant

throttle control models. In addition, there are model variations

with coil type or roller type load chains and hook or lug type

suspensions. Coil chain hoists are also provided in spark

resistant models. (Note: Spark resistant models have rated

loads of 3/8 and 3/4 ton.)

1-2. BASIC CONSTRUCTION. All sizes and models are of the

same basic design, having many common and interchangeable

parts. They consist primarily of an aluminum alloy frame which

houses a vane type air motor, chain sprocket wheel, and

gearing. A shoe-type brake is mounted on one end of frame

and is encased in an aluminum alloy end cover. A control

head assembly with built-in muffler and air inlet swivel

connection is mounted on opposite end of frame. An upper

suspension hook or lug bracket is attached to the top of the

frame. Either a special nickel steel roller type load chain or an

alloy steel coil type load chain with spring-latch type lower

block assembly is employed to raise and lower loads. A block

and chain operated limit stop lever is mounted at bottom of

frame and is pinned to throttle valve control shaft. Hoist

operation is controlled by either pull cords or a pendant throttle

control assembly.

1-3. DIFFERENCES BETWEEN MODELS AND SIZES. The

main differences between hoist models are in the type of

control, type load chain and type suspension employed. These

are described in paragraphs (a.) through (c.) below. Differences

between sizes are in reeving of the load chain. On 1/4 and 1/2

ton hoists, the load chain is single reeved (one part of chain);

on 1 ton hoists, the chain is double reeved (two parts of chain).

12018C 12019C 12020C

Standard lift is 10' though increased lifts may be ordered.

a. Control differences are in methods employed for operating

hoist. There are two types, pull cord control and pendant throttle

control. These are further described in Section III, paragraphs

3-1 and 3-3.

b. Two types of load chains are used as the lifting medium,

roller chain and coil chain. The roller type chain is a special

precision manufactured nickel steel chain. The coil type chain

is full-flexing, electric welded, link chain; carburized alloy steel

on standard models and surface hardened chrome-nickel

stainless steel on spark resistant models. Both types are

especially designed for use in hoisting.

c. Suspension differences include a conventional hook type

mounting and a lug type mounting. Hook suspension allows

portability, permitting hoist to be easily moved from job to job.

Lug suspension allows rigid trolley mounting of hoist on an

overhead I-beam to permit traversing hoist and load. Rigid

mounting of trolley on hoist affords maximum headroom

advantage, saving up to 3-3/16" compared to a hoist hook-

suspended on a trolley.

1-4. HOIST DATA.

SECTION II - INSTALLATION

2-1. GENERAL. BUDGIT Air Hoists are completely lubricated

and load tested before being shipped from the factory. To place

hoist in service, attach to a suitable overhead suspension

(Paragraph 2-2) in area to be used; connect hoist to nearest

air supply (paragraph 2-3); and check and adjust hoist speed

(paragraph 2-4).

2-2. SUSPENDING HOIST.

a. On hook suspended hoists, select a suitable overhead

support in area hoist is to be used (one capable of holding

combined weight of hoist and its rated load) and hang hoist

up. Be certain that upper hook is firmly :seated in center of

hook saddle and that the spring safety latch is properly

closed over hook opening. In some cases, it may be

necessary to first remove spring latch before hook will fit over

a support. Reinstall latch after hook is engaged.

b. On lug suspended hoists, select a suitable overhead support

in area hoist is to be used (one capable of holding combined

weight of hoist and its rated load). Mount hoist using through

bolts of appropriate size to fit mounting holes in suspension

lug at top of hoist. Use only suspension bolts provided by

YaleLift-Tech. (See table below.)

The structure used to suspend hoist must be of sufficient

strength to withstand reasonable forces to which hoist and

support may be subjected. Hoist must be aligned with

load to avoid side pulls.

CAUTION

If trolley is mounted on an open-end beam, end stops

must be installed to prevent trolley from running off

the end of the beam resulting in injury to operator and

other and damages to load and other property.

WARNING

c. On rigid mount trolley suspended hoists, the trolley side

plates must be properly spaced so trolley will fit (beam on

which hoist will operate. Adjustment for various I-beam sizes

is accomplished by rearrangement of spacer washers on

through bolts which connect trolley side plates to hoist

suspension lug. Refer to instruction sheet furnished with

BUDGIT Rigid Mount Trolleys for complete instructions.

d. If chain container is to be used on hoist, install it following

instructions furnished with container.

2-3. CONNECTING HOIST TO AIR SERVICE.

a. Connect hoist to nearest filtered and lubricated air source

using minimum 1/2" I.D. air hose assembly (see Figure 2-1).

Avoid use of reducing bushing and nipple or hose assemblies

of smaller diameters which may cause restrictions.

SUSPENSION LUG BOLT SIZE AND HOLE SPACING

c. A filter and lubricator unit (Figure 2-3) must be installed

between air source and air hose leading to hoist. These keep

air flowing to hoist free of dirt and add lubricant to air so

internal parts of motor are constantly lubricated. Use Air Hoist

Motor Oil or good grade IOW machine oil (approximately

viscosity 150 SSU at 100°F.) Multi-viscosity, detergent type

engine oil is not recommended. Feed one drop of oil for every

50 to 75 cubic feet of air going through the air motor.

Figure 2-2. Air Hoist Supported by BUDGIT Hoist Trolleys.

b. If hoist is suspended by trolley, provide sufficient hose to

reach from air source to farthest point of trolley travel. BUDGIT

Hose Trolleys are recommended to keep hose up out of the

way (see Figure 2-2).

Note: Hoist Speeds are shown in feet per minute (f.p.m.)

Maximum lowering speed with rated load is very high.

Adjust with care. Heads of adjusting screws should not

extend beyond outer surface of housing.

CAUTION

c. When the screwdriver slots on ends of adjusting screws are

horizontal (hoist in normal suspended position), the hoist speeds

will be at either minimum speed or maximum speed. Rotating

the screws 1800 in either direction will give a full adjustment

between minimum and maximum speed limits. Note: Screws

have arrow stamped on end to assist operator with adjustment.

SECTION III -OPERATION

3-1. GENERAL. Operation of BUDGIT Air Hoists is controlled

by either pull cords or a pendant throttle control, depending

upon the model. Pull Cord Control models have pull type

control cords (Figure 3-1) suspended from a rocker type lever

at bottom of hoist that actuates the throttle control valve.

Pendant Throttle Control models have a convenient lever type

control valve handle (Figure 3-2) suspended from the control

cylinders on sides of control head housing.

Do not lift more than rated load except for test

purposes. Overloading hoist can result in chain

breakage, hook deformation and other failures which

can cause serious injury and damage. A test at greater

than rated load should be a properly supervised official

test only, not an operator test. If any load sustaining

parts have been altered, replaced or repaired, hoist

should be load tested at 125% of rated load by a

designated, qualified person, with a written report

recording test load, as recommended in ANSI B30.16

Safety Standards.

WARNING

3-2. PREOPERATIONAL CHECKS. Check the following before

operating hoist with load:

a. Inspect chain anchor connections at side of hoist frame and

at upper hook or lug mounting bracket on 3/4 and 1 ton double

reeved models. Anchor screw or pin should be secure and not

bent or broken. Chain should be solidly anchored.

b. Check hoist brake for proper adjustment and operation. Refer

to Section V, paragraph 5-2, d.

c. Check hooks. They should not be bent or distorted and should

not be opened beyond the correct opening sizes given in Figure

5-3. Hook latches should not be bent or damaged and springs

not broken.

d. Check chain to make sure it is not twisted or kinked. Be sure

lower block (3/4 and 1 ton, double reeved models) has not

been capsized.

100 psi (while hoist is operating), it is recommended that a

pressure regulator valve be provided in the air supply line to

maintain proper pressure. However, there is a wide range of

pressures within which the hoists will operate. Refer to

“Performance Charts.” See Figure 2-5.

2-4. HOISTING AND LOWERING SPEED ADJUSTMENTS.

a. Hoist speed is adjusted at the factory to give maximum

lifting speed and is set at average between‘ minimum and

maximum lowering speed.

b. To adjust the hoisting or lowering speed, turn appropriate

regulator_ screw (Figure 2-4) in either direction a little at a

time while operating hoist under load.

Never operate hoist with defective chain anchor pins,

brake or hooks.

WARNING

e. Lubricate chain per paragraph 4-4.

3-4. PULLING AND PIVOTING HOIST AND LOAD.

a. On Pendant Throttle Control models, the valve handle is

supported by a strain cable that is suitable for pulling trolley

suspended hoists when empty or lightly loaded. Use a tag

line or pole to pull or push loads to traverse heavily loaded

hoists. Observe caution to stay clear of loads.

b. To pivot load, push on one corner of load. Lower hook will

swivel through 3600 to permit load to be swung to the desired

position. The upper hook (hook suspension models) is also

designed to rotate so that side pulls will swing hoist to face the

load, thus reducing side thrust.

3-5. UPPER AND LOWER LIMIT STOPS. A lower block and

chain operated limit stop is provided to guard against over

travel of load in either raising or lowering direction, which can

cause damage to hoist. When highest position is reached, the

lower block trips the control lever (Figure 3-3). When lowest

position is reached, the tail end of load chain trips the control

lever (Figure 3-4). The control lever is connected to the control

shaft which actuates inlet valves controlling air pressure to air

motor. Limit stops are intended as safety devices and should

not be used as a routine basis to stop travel of lower block or

shut off hoist.

Equipment covered herein is not designed or suitable

as a power source for lifting or lowering persons.

WARNING

Safe operation of an overhead hoist is the operator’s

responsibility. Listed below are some basic rules that can make

an operator aware of dangerous practices to avoid and

precautions to take for his own safety and the safety of others.

Observance of these rules in addition to frequent examinations

12011A

Figure 3-3. Control Lever Being Tripped by Lower Block.

12012A

Figure 3-4. Control Lever being Tripped by

Tail End of Load Chain.

Page 7

and periodic inspection of the equipment may save injury to

personnel and damage to equipment.

a. Operate hoist cautiously to become familiar with its

performance.

b. Do not load hoist beyond rated load.

c. Take up chain slack carefully to avoid jerking load.

d. Never use hoist load chain as a sling.

e. Always be sure there is no twist in coil load chain. On 3/4

and 1 ton hoists, check to see that lower block is not

capsized between strands of chain.

f. Check both upper and lower limit stop operation by raising

or lowering empty hook to limit of travel. Hoist must shut

off.

g. When lifting load, make certain it is free to move and will

clear all obstructions.

h. Stand clear of all loads and never lift or travel loads over

people.

j. Avoid operating hoist when hook is not centered under

hoist. Be sure that hoist trolley or other support mechanism

is correctly positioned for handling the load before lifting.

k. Guide load so as to have it under control at all times.

I. Do not operate hoist with twisted, kinked or damaged

chain.

m. Do not operate damaged or malfunctioning hoist.

n. Conduct periodic visual inspection for signs of damage

or wear.

o. Observe inspection and maintenance procedures

described in this manual.

p. Never lift or transport a load until all personnel are clear.

Never lift people on hook or load.

q. Do not divert attention from load while operating hoist.

Never leave a suspended load unattended.

r. Do not use limit stop as normal operating stop. This is a

safety device only.

s. Do not “jog” unnecessarily.

t. Personnel not physically fit or properly qualified, shall

not operate hoist.

u. Do not remove or obscure warning labels.

v. Use common sense and best judgement whenever

operating a hoist. Observe American National Standard

Safety Standard, ANSI B30.16 latest issue.

SECTION IV - LUBRICATION

4-1. GENERAL. The lubrication services outlined in paragraphs

4-2 through 4-7 should be performed at regular intervals to

maintain top hoist performance and insure long life. Frequency

of lubrications will depend on type of hoisting service hoist is

subjected to and should coincide with preventive maintenance

inspections. See Section V - Maintenance.

4-2. SERVICE AIR LINE LUBRICATOR. Servicing air line filter

and lubricator unit is of primary importance since it is the only

source of lubrication for control valves and air motor. Fill

lubricator with Air Hoist Motor Oil or good grade 10W machine

oil (approximate viscosity 150 SSU at 100°F.). Multi-viscosity,

detergent type engine oil is not recommended.

4-3. GEARCASE. The gearcase is grease packed at the factory

and requires no further greasing unless the gearcase is for

any reason disassembled. Then, at reassembly, the parts

should be washed clean (using commercial fluid) and

repacked with NLGI EP-2 Grease.

4-4. LUBRICATE LOAD CHAIN. A small amount of lubricant

will greatly increase load chain life; therefore, chain should

not be allowed to run dry. Chain should be cleaned and

lubricated as directed in paragraphs a. and b. below,

depending upon type of chain. User should set up a regular

schedule for chain lubrication after observing operating

conditions for a few days. Use Bar and chain Oil (LUBRIPLATE

or equal) on load chain.

a. Coil Chain. Under ordinary conditions, only weekly attention

will be necessary for alloy steel chain. Under hot and dirty

conditions, it may be necessary to clean chain at least once a

day and lubricate it several times between cleanings.

Thoroughly clean chain with an oil solvent and relubricate by

coating it lightly with penetrating oil and graphite. Make sure

that lubricant coats wear surfaces between links.

Stainless steel load chain must be well lubricated at all times

and must be inspected daily when in use.

b. Roller Chain. Under ordinary conditions, only monthly

attention will be necessary. Under hot and dirty conditions,

weekly attention may be required. Thoroughly clean chain with

an oil solvent and apply a good grade of S.A.E. 20 motor oil.

Wipe off excess oil. When subjected to excessive moisture or

corrosive atmospheres, DO (dripless oil) lubricant from

American Grease Stick Company is recommended for use on

roller chain in place of regular motor oil.

4-5. LUBRICATE UPPER HOOK AND LOWER BLOCK

ASSEMBLY.

a. On 3/4 and 1 ton hoists, apply a few drops of S.A.E. 60 oil

on shank of upper hook where it enters suspension bracket.

b. On single line hoists (1/4, 3/8 and 1/2 ton) disassemble

upper and lower hooks as described in 7-2.b.(4) and grease

thrust bearings with a good grade of bearing grease.

c. On double line hoists (3/4 and 1 ton) lower blocks,

disassemble as described in 7-2.b.(5) and grease needle

bearings for sprocket shaft and hook with a good grade of

bearing grease.

4-6. LUBRICATE CONTROL SHAFT, BRAKE CAM AND

VALVE SHIFTER.

a. Apply a few drops of S.A.E. 60 oil on control shaft at bearing

points.

b. Apply graphite grease on valve shifter and on brake cam.

4-7. LUBRICATE TROLLEY WHEEL BEARINGS. If hoist is

mounted on a trolley, apply light grease to wheel bearings as

recommended by trolley literature.

Before performing any internal work on hoist, remove

load and be certain air is shut off.

WARNING

SECTION V - MAINTENANCE

5-1. GENERAL. Preventive maintenance services required on

Page 8

BUDGIT Air Hoists are for the most part simple periodic

inspection procedures to determine condition of hoist

components. Below are suggested inspection procedures,

based on daily average hoist usage.

Hoist subjected to severe service or to adverse

environments should be examined weekly or as conditions

warrant.

5-2. THIRTY-DAY INSPECTION. Hoist may be left suspended.

a. Inspect Load Chain.

(1) Operate hoist under load and observe operation of chain

over sprocket in both directions of chain travel. Chain should

feed smoothly into and away from the sprocket. If chain binds,

jumps or is noisy, first see that it is clean and properly lubricated.

If trouble persists, inspect chain and mating parts for wear,

distortion or other damage.

(2) Coil Type Load Chain. Clean chain for inspection.

Examine visually for gouges, nicks, weld splatter, corrosion or

distorted links. Slacken chain and check bearing surfaces

between links for wear, Figure 5-1. Greatest wear will often

occur at sprocket at high or low point of lift, particularly when

hoist is subjected to repetitive lifting cycles. Case hardness of

chain is about .015" deep. Chain must be replaced before the

case is worn through. Also check chain for elongation using a

vernier caliper (Figure 5-2). Select an unworn, unstretched

section of chain (usually at slack or tail end) and measure and

record the length over the number of chain links (pitches)

indicated in Figure 5-2. Measure and record the same length of

a worn section in the load side of the chain. Obtain the amount

of wear by subtracting the measurement of the unworn section

from the measurement of the worn section. If the result (amount

of wear) is greater than the amount specified in the

“ALLOWABLE CHAIN WEAR” table, the chain has elongated

beyond the maximum allowable length and must be replaced.

Chain with excessively pitted, corroded, nicked, gouged, twisted

or worn links should be replaced using only factory approved

chain. Never weld or attempt to repair coil chain.

Load chain for spark resistant models is made of stainless steel.

Surface hardness treatment is no more than .001" deep and

the core is lower in hardness than standard alloy steel load

chain. For these reasons the rated capacity of spark resistant

models is lower than that of standard models as follows:

Do not assume that load chain is safe because it measures

below replacement points given herein. Other factors, such

as those mentioned in visual checks above, may render

chain unsafe or ready for replacement long before

elongation replacement is necessary.

CAUTION

(3) Roller Type Load Chain. Visually check for possible

twists, broken links, wear or elongation. Check roller chains

for elongation from wear by pulling chain taut and measuring

as follows: On RC-625 or H-5 size chain (5/8" pitch), measure

distance over a length of 20 pitches (center-to-center distance

between 21 rivets) - it must not exceed 12-3/4 inches. If chain

exceeds this limit, replace damaged section or install new

load chain assembly. Check chain for twist. If twist in any 5'

extension exceeds 15°replace chain. Check chain for camber.

If any section has side bow exceeding 1/4" in five feet, replace

chain. Use only factory approved chain. If chain is to be spliced

to replace damaged section, it is recommended that this be

done by a recognized BUDGIT Repair Station, since splicing

link must have a spun head requiring special tools. Spring

link must not be used except to secure the tail chain to the

hoist frame. (See Figure 7-1.)

Figure 5-2. Checking Coil Chain Using Vernier Caliper.

Figure 5-1. Check Chain Wear at Bearing

Surfaces Between Links.

It must not be assumed that load chain is safe because it

measures below replacement points given herein. Other

factors, such as those mentioned in visual checks above,

may render chain unsafe or ready for replacement long

before elongation replacement is necessary.

CAUTION

When replacing coil load chain, use only factory

approved chain conforming to factory specifications

for material, hardness, strength and link dimensions.

Chain not conforming to BUDGIT hoist specifications

may be dangerous as it will not fit in the load sprocket

and chain guide correctly, causing damage to hoist

and it will wear prematurely, deform and eventually

break.

(4) Check anchor end of chain at side of hoist frame for

damage to last link, also connecting link on roller chain hoists.

Replace damaged parts.

(5) Check connection of chain to lower block on 1/4, 3/8

and 1/2 ton hoists. Replace parts showing evidence of

damage, twisting or elongation.

(6) Check connection of chain to anchor on side of

suspension bracket on double reeved, 3/4 and 1 ton hoists.

Replace parts showing evidence of damage, twisting or

elongation.

(7) Lubricate load chain if required. See paragraph 4-4,

Section IV.

b. Inspect Lower Block.

(1) Check for bent or distorted hook. If hook is opened beyond

the dimension given in Figure 5-3, it must be replaced. Also

check to see that hook swivels, and is free to pivot on roller

chain models. Lubricate these points if necessary.

(2) On 3/4 and 1 ton hoists, check sprocket and bearings in

lower block for freedom of movement and signs of damage.

Lubricate if necessary. Replace damaged parts.

c. Inspect Upper Suspension.

(1) On hook suspended models, check for bent or distorted

hook. If hook is opened beyond the dimension given in Figure

5-3, it must be replaced. Also check to see that hook swivels.

Lubricate if necessary.

(2) On push trolley suspended models, check condition of

trolley parts and lug bracket. Replace bracket or any trolley

parts which are damaged or cracked.

(3) Check hook latch. Replace damaged or bent latch or

broken spring.

d. Check Brake Operation.

(1) With air turned on and with rated load attached to lower

hook, operate hoist to raise load, applying pressure to pull

cord handle or throttle control lever. If load drifts down before

the motor starts to actuate, the brake is out of adjustment.

(2) To adjust brake, insert hex key through hole in brake

cover. Turn screw counterclockwise to tighten brake or clockwise

to loosen brake (see Figure 7-15).

5-3. ANNUAL INSPECTION. Hoist must be disconnected from

air service and removed from overhead suspension. Hoists

subjected to severe service or to adverse environments

should be examined weekly or as conditions warrant.

a. Hoist should be partially disassembled as necessary to

inspect hoist parts noted in paragraphs b. through h. below.

Refer to Section VII for disassembly and reassembly steps as

noted.

b. Inspect Brake. Remove brake housing cover and brake

shoes as outlined in paragraph 7-2.c. Check brake shoe linings

and brake wheel for wear and scoring. Replace badly worn or

scored parts. Check condition of brake cam and spring. Replace

any damaged parts.

c. Inspect Internal Load Gears. Remove gear plate and

intermediate gears as outlined in paragraph 7-2.f. Check

condition of gear teeth on internal gear, intermediate gears,

and motor shaft pinion. Replace worn or damaged parts.

d. Inspect Chain Sprocket and Bearings. Remove sprocket

and internal gear as a unit, paragraph 7-2.f. Check condition of

teeth or pockets on chain sprocket and inspect ball bearing

assemblies. Replace worn or damaged parts.

e. Inspect Throttle Valve Shifter. Remove valve shifter and

control shaft (paragraph 7-2.c.) and shifter pin (paragraph 7-

2.d.). Check condition of shifter, pin and shaft bearings. Replace

worn or damaged parts.

f. Inspect Throttle Valve Housing. Remove throttle housing

assembly (paragraph 7-2.d.) and disassemble it as outlined.

Check condition of throttle valve, valve bushing (in housing)

and “0”rings on valves. Replace worn or damaged parts.

g. Inspect Air Motor. Remove air motor assembly from hoist

(paragraph 7-2.e.). Check motor for condition of bearings,

possible rotor rubbing on body or end plates, blade freedom in

rotor slots, shaft and gear. If motor appears to be in good

condition, do not service other than lubricating well with light

oil.

h. Reassemble and Test Hoist. Reassemble hoist as outlined

in Section VII, paragraph 7-4. After reassembly, test hoist in

accordance with paragraph 7-5.

Hooks, upper or lower, damaged from chemicals,

deformation or cracks or having more than 15 percent

in excess of normal throat opening or more than 10

degrees twist from the plane of the unbent hook, or

opened, allowing the hook latch to bypass hook tip

must be replaced.

Any hook that is twisted or has excessive throat

opening indicates abuse or overloading of the hoist.

Other load bearing components of the hoist should be

inspected for damage. (See Section V, paragraph 5-3

below.)

WARNING

(3) Check hook latches. Replace damaged or bent latches

or broken springs.
