be used with the hoist. Refer to Section 3.3.

CAUTION

ensure its proper operation. The air must be clean and free of debris such as dirt and rust. Refer to

Section 3.4 for filtration requirements. The air must also be dry; free of moisture and water. Refer to
Section 3.5.

Pressure and Flow - Verify that the air supply system has capacity to supply your

Lubrication - The hoist requires lubrication for proper operation. The oil in the air

Air Quality - Good air quality is essential to prevent damage to your hoist and to

3.2 Air Supply Capacity And Regulation

3.2.1 Capacity - The air supply system must be capable of delivering the required airflow (cfm) to the hoist
inlet port. Without the required airflow the hoist will not operate properly or may not operate at all. See

Section 2.0 for your hoists air consumption requirements. In determining if your system is capable of

supplying the required airflow, consider the following:

 Capacity of compressor(s) and tank

 Other air consuming equipment

 Flow restrictions such as pipes, hoses, valves and fittings

Inadequate capacity will cause a significant drop in pressure when the hoist is operated, and could
cause poor performance or failure to operate.

3.2.2 Regulation - The hoist requires a constant supply of air at a pressure of between 60 and 90 psi. If the
air supply is not regulated or is regulated at a pressure greater than 90 psi, then a regulator must be
used. The regulator may be located anywhere upline of the lubricator in the air supply to the hoist.

3.3 Lubrication

3.3.1

3.3.2

CAUTION

as follows:

1) Best location - At the hoist inlet. In this case the lubricator can be either the mist type or drop

type.

2) Second best location - No more than 15 feet away from the hoist, at the same elevation or

above the hoist inlet. In this case the mist type lubricator must be used.

3) Third best location - No more than 15 feet away below the hoist. In this case the mist type

lubricator must be used.

CAUTION

4.5 Operation of the Load Limiter

4.5.1 If a hoist is used to lift a load that exceeds the hoists rated capacity, the load limiter will cause the hoist

to automatically stop lifting.

4.5.2 If the hoist stops lifting automatically, lower and remove the load from the hoist.

4.5.3 If the load is at or below the hoist’s capacity rating and the hoist stops lifting automatically, the load

limiter may need adjustment.

 Check air line pressure to ensure adequate pressure at the hoist.

 If pressure is adequate, adjust the load limiter. For load limiter adjustment, refer to Section 7.

5.2 Inspection Classification

5.2.1 Initial Inspection - prior to initial use, all new, altered, or modified hoists shall be inspected by a
designated person to ensure compliance with the applicable provisions of this manual.

5.2.2 Inspection Classification - the inspection procedure for hoists in regular service is divided into two
general classifications based upon the intervals at which inspection should be performed. The intervals
in turn are dependent upon the nature of the critical components of the hoist and the degree of their
exposure to wear, deterioration, or malfunction. The two general classifications are herein designated
as FREQUENT and PERIODIC, with respective intervals between inspections as defined below.

5.2.3 FREQUENT Inspection - visual examinations by the operator or other designated personnel with
intervals per the following criteria:

 Normal service - monthly

 Heavy service - weekly to monthly

 Severe service - daily to weekly

 Special or infrequent service - as recommended by a qualified person before and after each

occurrence.

5.2.4 PERIODIC Inspection - visual inspection by a designated person with intervals per the following criteria:

 Normal service - yearly

 Heavy service - semiannually

 Severe service - quarterly

 Special or infrequent service - as recommended by a qualified person before the first such

occurrence and as directed by the qualified person for any subsequent occurrences.

7.0 Maintenance and Handling

7.1 Load Limiter

7.1.1 The purpose of the load limiter is to prevent using the hoist in an overload situation. When lifting, the
hoist will stop automatically if the load is above the rated capacity of the hoist.

7.1.2 The adjustment is factory set to actuate at approximately125% of rated capacity (based on supply air
pressure of 90 PSI). Note: the load limiter may need adjustment to compensate for air supply
pressures significantly less than 90 PSI.

Figure 7-1 Load Limiter screw adjustment location

7.1.3 Adjustment Procedure

1) Before proceeding with the load limiter adjustment, note the following:

a.

WARNING

Adjusting the load limiter involves operating the hoist. Personnel involved

in the adjustment procedure should read, understand, and follow Section 4, "Operation".

b. For the adjustment procedure, the hoist should be connected to an air supply (see Section 3.1)

and it should initially be without a load on its hook.

c. Start this procedure with an unloaded hoist. All adjustments to the load limiter should be made

with the load in a resting position so that the load chain is not tensioned.

d. For the adjustment procedure: OUT means the counter-clockwise (CCW) direction, and IN

means the clockwise (CW) direction.

e. The pressure of the air supply at the hoist’s inlet port (acceptable range is 60 to 90 PSI) affects

the performance of your air hoist, including the actuation point of the load limiter. Therefore,
ensure that during the adjustment procedure the air pressure at the hoist's inlet port is the
same as that which the hoist will experience in normal operation. The relationship between air
supply pressure and load limiter actuation is:

 For a given load limiter setting, as pressure decreases, the actuation point increases.

f. When the load limiter is adjusted and working properly, the hoist will operate and lift the load a

short distance before the load limiter automatically stops lifting.

2) Refer to Figure 7-1. Loosen the lock nut and slowly turn the adjustment screw OUT until it is loose and

no longer is in contact with the internal load limiter spring – as this occurs the screw should become
easier to turn. Stop turning the screw once it is loose and easier to turn.

3) Turn the adjustment screw IN just enough so that it begins to contact the internal load limiter spring –

as this occurs the screw should become slightly harder to turn.

32

4) Put a load equal to the desired actuation point on the hoist's hook (do not exceed 125% of the hoist's

rated capacity). Begin to slowly lift the load, then increase the lifting speed. Return the load to its
resting position so the load chain is not under tension.

5) If the load limiter prevents lifting, turn the adjustment screw IN one full turn.

6) Repeat steps 4 and 5 until the load limiter allows lifting.

7) Turn the adjustment screw OUT ¾ of a turn.

8) Attempt to lift the rated capacity load again, beginning slowly, then increasing the lifting speed.

9) If the load limiter does not allow lifting, then turn the adjustment screw IN ¼ turn.

10) Repeat steps 8 and 9 until the load limiter allows lifting.

11) Turn the adjustment screw IN ¼ turn. Then, while holding the adjustment screw, tighten the lock nut to

secure the setting.

7.2 Brake

7.2.1 For Load Brake setup and adjustment procedure consult factory.

7.2.2 Inspect the brake disc in accordance with Section 5.7, Table 5-3.

7.2.3 The following is the hoist brake inspection procedure. Refer to Figure 7-2.

1)

WARNING

HAZARDOUS AIR PRESSURE IS PRESENT IN THE HOIST, IN THE
SUPPLY OF COMPRESSED AIR TO THE HOIST, AND IN THE CONNECTIONS BETWEEN
COMPONENTS. Shut off the air supply and stop the airflow completely. Lock out and tag out in
accordance with ANSI Z244.1 “Personnel Protection -Lockout/Tagout of Energy Sources”.

2) Do NOT turn or remove the brake adjustment screw located in the center of the brake cover.

3) Gradually back out all four hex socket cap screws from brake cover to slowly decrease spring

tension of brake piston against brake disc.

4) Remove brake cover from the motor housing top of gear case. Keep brake piston, springs, seals,

etc. together inside the brake cover.

5) Remove brake disc for inspection and measurement. Refer to "Motor Brake" in Table 5-3, "Hoist

Inspection Methods and Criteria".

6) Prior to reassembly, clean all surfaces of debris, dirt and loose paint.

7) Reassemble in reverse order. Torque all mounting hardware evenly during the reassembly

process.

set assemblies, limit locks, stoppers and end connections from the chain for reuse on new chain. If
the load chain is being replaced due to damage or wear out, prevent its reuse by destroying the old
chain.

4) Remove the existing Load Chain – Lower the bottom hook assembly until it rests on the ground or

is supported by some other means. Disconnect the no-load and load end of the load chain from
the hoist. Run the hoist in the down direction to remove the chain form the hoist body.

5) Run the hoist in the up or down direction until the load sheave is positioned as shown in Figure 7-3.

An air supply line must be connected to the hoist in order to perform the

Be certain that the replacement chain is obtained from Harrington and is the

When replacing load chain, check for wear on mating parts, i.e. Load Sheave,

6) Without operating the hoist, tie a wire to the end of the new load chain, then thread the wire

through the hoist over the load sheave. Pull the wire so that the load chain enters the hoist
making certain that the first link is a standing link and that its weld is facing away from the
centerline of the hoist.

34

7) While pulling on the wire, SLOWLY operate hoist in the DOWN direction to thread the load chain

over the load sheave. Make sure the chain feeds smoothly while operating the hoist. If binding
occurs, stop and SLOWLY operate the hoist in the up direction to the back the chain out, then
reorient the load sheave as instructed in step 5 before attempting to reinsert the load chain.

8) Operated the hoist in the down direction until sufficient there is sufficient load chain to reeve the

hoist.

9) Reeve the chain through the bottom hook assembly. Remove the wire from the Load chain and

attach the no-load and load end of the load chain to the hoist. Ensure that chain remains free of
twists.

10) After installation has been completed, perform steps outlined in Section 3.12 "Preoperational

Checks and Trial Operation".

7.4 Pendant

7.4.1 The following procedure covers the installation of a pendant control station.

1) Attach the strain relief chain and the three hoses to the pendant station.

2) Attach the strain relief chain to the hoist valve body with the socket bolt as shown in Figure 7-4.

3) Attach the three hoists to the fittings on the hoist's valve body. Refer to Figure 7-4 and make sure

the up, down and supply hoses are attached to the correct locations.

4)

NOTICE

When attaching tubes take care not to bend or kink tubing. This will result in

the air flow being restricted and poor response to the pendant controls.

5) Attach the hoist to supply air. Check for leaks and properoperation.

6)

WARNING

The pendant hoses hoist must be connected so that its direction of operation
corresponds to the up-and-down lever on the pendant control; i.e. pushing the up button must
cause the hook to raise. If the hoist does not operate correctly, shut off the air supply to the hoist
and correct the pendant connections.

Figure 7-4 Pendant Hose and Strain Relief Connections

36

7.5 Storage

7.5.1 Whenever the hoist is to be placed into storage, place extra lubricating oil into the air inlet opening and
circulate the air motor before plugging the inlet. Make certain that no debris, dirt or moisture is allowed
to enter the air hoist through air inlet opening during preparations for storage.

7.5.2 The storage location should be clean and dry.

7.6 Outdoor Installation

7.6.1 For hoist installations that are outdoors, the hoist should be covered when not in use.

7.6.2 In order to prevent internal corrosion from occurring, the hoist must be operated using proper quality air
at least once per week by raising and lowering the hoist one full cycle. Note: the possibility of corrosion
in the valve section of the hoist increases for areas where salt air and high humidity are present. For
such situations you may need to operate your hoist more often than once per week.
