Ingersoll Rand HA1 Manuel D'installation page 3

Each hoist is supplied from the factory with the warning label shown. If
the label is not attached to your hoist, order a new label and install it.
HA1 Hoist
The HA1 air powered hoist primarily consists of a power head assembly
which acts as the control for the lower hook block movement. The
power head assembly is made up of three main sections. They are the
motor and first gear reducer section, the brake and second gear reducer
section and the sheave section.
The output shaft from the piston motor is connected to the first
planetary reducer assembly. The output from the first planetary reducer
assembly is connected to the brake by the input shaft which passes
through the center of the sheave section. The input shaft also acts as the
sun gear for the second stage planetary reducer. The output from the
secondary planetary reduction assembly is transmitted directly to the
load chain sheave.
The input shaft cannot rotate in either direction until the brake has been
released. The brake is released by air pressure applied to the annular
brake piston. The piston compresses the brake springs, releasing the
brake discs. There are five sintered bronze type brake friction discs and
six stationary brake discs.
The brake piston is actuated by air from the main control valve. When
the control pendant "UP" or "DOWN" button is pushed it moves the
main control valve spool. The spool is designed to send air to the brake.
When the pendant "UP" or "DOWN" button is released, quick exhaust
valves allow the brake to set quickly and avoid downward load drift.

Notes: 1. HA1 load chain standard size = 16 mm; HA2 load chain standard size = 22 mm.
2. Sound measurements have been made in accordance with ISO 11201, ISO 3744-3746 and ISO 4871 test specifications for sound from pneumatic
equipment. Readings shown are based on the average noise level of each hoist configuration, proportionate to the utilized time in a regular cycle.
3. LpC (Peak Sound Pressure) does not exceed 130 dB.
4. Performance based on 7.2 bar operating pressure.

HA2 Hoist
The HA2 air powered hoist primarily consists of a power head assembly
which acts as the control for the lower hook block movement. The
power head assembly is made up of three main sections. They are the
gear reducer section, the brake/motor section and the sheave section.
The output shaft from the piston motor is connected to the brake shaft.
The brake shaft is connected to the drive shaft by way of a coupling
which passes through the center of the brake and sheave section and
acts as the sun gear for the first stage planetary reducer. The gear
reducer section consists of three planetary assemblies with each
planetary assembly being driven by the sun gear from the previous
planetary assembly. The output from the planetary reduction section is
transmitted directly to the load chain sheave(s).
The motor driven brake shaft is connected to the brake through a sprag
clutch. In the hoist "UP" direction the clutch allows the shaft to rotate
without releasing the brake. No air pressure is applied to the brake
piston in the "UP" direction.
The brake shaft cannot rotate in the hoist "DOWN" direction until the
brake has been released. The brake is released by air pressure applied to
the annular brake piston. The piston compresses the brake springs
releasing the brake discs. There are four sintered bronze type brake
friction discs and five stationary brake discs.
The brake piston is actuated by air from the main control valve. When
the control pendant "DOWN" button is pushed it moves the main
control valve spool. The spool is designed to send air to the brake in the
"DOWN" direction only.
When the pendant "DOWN" button is released, quick exhaust valves
allow the brake to set quickly and avoid downward load drift.
