3.0 Preoperational Procedures
3.1 Air Supply System Requirements
3.1.1

Pressure and Flow - Verify that the air supply system has capacityto supply your
air hoist with required pressure and flow. Otherwise the hoist mayoperate poorly or may fail to
operate. See Section 3.2.
3.1.2

Lubrication - The hoist requires lubrication for proper operation. The oil in the air
supplyis the primarysource of lubrication to the hoist. Therefore, a dedicated air supply lubricator must
be used with the hoist. Refer to Section 3.3.
3.1.3

Air Quality- Good air quality is essential toprevent 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 airmust 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 supplysystem 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 maynot 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 maybe located anywhere upline of the lubricator in the air supply to the hoist.
3.3 Lubrication
3.3.1

The hoist must be supplied with its own lubricator. The lubricator must be located
as follows:
1) Best location - At the hoist inlet. In this case the lubricator canbe 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 belowthe hoist. In this case the mist type
lubricator must be used.
3.3.2

The lubricator must be set to deliver the equivalent of 10 to 15 drops of oil per
minute (0.2-0.3 cc/minute). The hoist’s exhaust will emit a fine oil mist when properly lubricated.

14
3.4 Filtration
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.
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.
3.5 Air Dryer -

To prevent corrosion and hoist malfunction, employ an air dryer in the air
supplysystem to ensure that dry air is supplied to the hoist. If there ismoisture 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.
3.6 Piping, Hoses And Fittings
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 mayresult if the system is
not periodicallydrained.
Arrange for a drain in the air supply piping at the lowest point in the piping, and
Periodically drain the system to removemoisture/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.
Figure 3-1 Diagram of Air SupplyConfiguration (Typical)
Figure 3-2 Typical Air Supply Filter, Regulator, and Lubricator.

15
3.6.2

Piping - Pipe should be sized to accommodate the hoist airflow requirements.
Table 3-1 gives recommended pipe sizes.

TCS500C/P
TCS1000C2/P2
Inside diameter
3/4” or larger
Inside diameter
1/2” or larger
3.6.3

Hoses - The connection from the air supplysystem piping to the hoist must be
made with a flexible pressure hose. Due to normal line losses in air supply lines:
Do not use hose smaller than specified in Table 3-1, and
Limit the length of the hose to that specified in Figure 3-3.
If your application exceeds these requirements consult factory.
Figure 3-3 Typical Arrangements of Filter,Regulator and Lubricator and
Maximum Air Supply Hose Lengths
3.6.4

Fittings - Importantconsiderations regardingfittings inthe hoist's air supply
include:
When connecting air supplycomponents, remove all dirt or debris from the connecting surfaces of
the hoses, pipes, fittings, or threaded fasteners to prevent contaminants from entering the hoist.
Keep airflowrestrictions such as quick disconnect fittings, bends, elbows, and adapters to a
minimum.
3.6.5

Before connecting the hoist to its air supply line; perform the proper draining and
purging procedures to prevent contaminants or moisture from entering the hoist.

16
3.7 Mounting Location
3.7.1

Prior to mounting the hoist ensure that the suspension and it supporting structure
are adequate to support the hoist and its loads. If necessaryconsult a professional that is qualified to
evaluate the adequacyof the suspension location and its supporting structure.
3.7.2

