3.0 Preoperational Procedures
3.1 Air Supply System Requirements
NOTICE
3.1.1
3.1.2
3.1.3
Pressure and Flow - Verify that the air supply system has capacity to supply your
air hoist with required pressure and flow. Otherwise the hoist may operate poorly or may fail to
operate. See Section 3.2.
CAUTION
Lubrication - The hoist requires lubrication for proper operation. The oil in the air
supply is the primary source of lubrication to the hoist. Therefore, a dedicated air supply lubricator must
be used with the hoist. Refer to Section 3.3.
CAUTION
Air Quality - Good air quality is essential to prevent damage to your hoist and to
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.
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
CAUTION
as follows:
3.3.1
The hoist must be supplied with its own lubricator. The lubricator must be located
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
3.3.2
The lubricator must be set to deliver the equivalent of 10 to 15 drops of oil per
minute (2 to 3 cc/minute). The hoist’s exhaust will emit a fine oil mist when properly lubricated.
3.4
Filtration
CAUTION
3.4.1
The air entering the hoist inlet must not contain any particulate greater than 5
microns in size. Therefore, the hoist must have a 5 micron filter in its air supply. The filter must be
upstream of the lubricator.
12
Download from Www.Somanuals.com. All Manuals Search And Download.
3.4.2 The filter servicing the hoist can also service other hoists and air consuming equipment. In this case,
the air filter must be in sized for the total air consumption of the equipment it is servicing.
CAUTION
To prevent corrosion and hoist malfunction, employ an air dryer in the air
supply system to ensure that dry air is supplied to the hoist. If there is moisture in the air supplied to the hoist,
this moisture will cause corrosion on internal hoist components during periods when the hoist is idle leading to
hoist malfunction.
3.5
3.6
Air Dryer -
Piping, Hoses And Fittings
CAUTION
3.6.1
System Configuration - The system should be configured as shown in Figure 3-1.
Since moisture tends to accumulate in compressed air systems, corrosion may result if the system is
not periodically drained.
ꢀ
ꢀ
ꢀ
Arrange for a drain in the air supply piping at the lowest point in the piping, and
Periodically drain the system to remove moisture/water from the system and to prevent corrosion.
Filter, regulator (if equipped), and lubricator must be arranged in the order shown in Figure 3-2.

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:
WARNING
a.
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
Download from Www.Somanuals.com. All Manuals Search And Download.
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.
WARNING
1)
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.

Load Chain
7.3.1 Lubrication and Cleaning
ꢀ
ꢀ
Clean the chain with an acid-free cleaning solution. The load chain should be kept clean and
lubricated.
Lubrication - Clean and lubricate the load chain per Section 6 at least once every 3 months for
normal usage. Clean and lubricate more frequently for heavier usage or severe conditions.
7.3.2 Replacement
CAUTION
1)
An air supply line must be connected to the hoist in order to perform the
following procedures. The hoist must accessible and must be hanging from the top hook
assembly.
WARNING
2)
3)
Be certain that the replacement chain is obtained from Harrington and is the
exact size, grade and construction as the original chain.
CAUTION
When replacing load chain, check for wear on mating parts, i.e. Load Sheave,
Chain Guides and Idle Sheave, and replace parts if necessary. Remove old chain. Remove hook
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.
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
Download from Www.Somanuals.com. All Manuals Search And Download.
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".

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.
NOTICE
4)
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.
WARNING
6)
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.
