Benefits of using an Ingersoll-Rand air chain hoist:
The CE mark on the MLK and HLK hoists is your assurance all
the safety features are included in compliance with the European
Air hoists can be operated continuously, as air motors don’t
Dust, dirt, moisture and corrosive gases are kept out of the
motor by the air pressure that runs it. This basic fact makes
air hoists the first choice in foundries, electroplating shops,
As no electricity is used, the freedom from electric shock and
the use of air power in explosive environments are obvious advantages.
This is why air hoists are used extensively in flammable environments
found in chemical plants, refineries, etc. Spark resistant models
are also available.
Simple speed and directional controls provide precise spotting
capabilities. Manual, easy to operate air valves admit air to
the motor through a variable orifice. Complete control, from
an inching crawl to full speed, is available without expensive
electric control systems.
Motor, brake and throttle parts are interchangeable with all
current Ingersoll-Rand air chain hoists.
Ingersoll-Rand air chain hoists are designed and constructed for
trouble-free maintenance. The inherent durability of air power
contrasts with the potential problems of electrical systems!
Features and Benefits:
type swivel hooks – top and bottom
Supported by anti-friction bearings. Bullard Burnham hooks available
for all models, except spark resistant.
All bearings are either ball or roller type to minimise power-robbing
Reduces sound level to 85 dBA. Located internally in valve chest
for protection against damage. Element is woven to prevent corrosion
swivel, strainer and filter.
Combined to allow easy hookup from any direction. Swivel reduces
hose fatigue, especially on hook-mounted units. Strainer nipple
and internal filter provide that extra assurance of clean air
for maximum wear protection.
air shut-off valve.
Stops the main air supply to the motor when the emergency stop
button on the pendent is pushed (as per EN418 standards).
For smooth operation and metering of air. Valves are poppet type
for ease of maintenance.
Cycle Multi Vane® motor.
High torque, low maintenance design with air porting under vanes
for smooth operation, positive starting, good control and long
Adjusted at the factory at 140 to 150% of the safe working load.
Fitted as standard on HLK’s (Optional on MLK’s).
Provide sensitivity and maximum speed control for pendent models.
Adjustment of screws will provide maximum control for each hoisting
progressive pilot pendent control.
Furnishes a variable pressure signal to the valve chest where
flow to hoist is metered accordingly. Air to run hoist motor does
not travel through pendent, thus pendent length does not affect
performance. Control hoses are flexible and easily converted to
different lengths. Guards on either side of levers are cast-in
for protection against accidental operation.
In the event of an emergency situation the operator can safely
stop the hoist (and trolley).
single-line hook block.
Two-piece, “clam shell” design entraps chain links and hook bearing
without using small load bearing pins or fasteners.
Zinc plated steel chain is standard. Stainless steel chain is
available for the 0.5 ton through 1 ton spark resistant models.
Fabric or metal container, as an accessory, to keep slack chain
out of the way.
and lower limit stops.
Prevent dangerous overtravel of the hook in either direction,
reducing possible damage to hoist or load.
Slack chain is guided into drive wheels by a specially designed
opening which prevents dangerous cross-linking of chain.
air chain lubrication
A small amount of exhaust air flows over chain and drive wheel.
This flow lubricates chain from spent in-line lubrication of motor.
non-asbestos, self-adjusting disc brake.
Air-operated disc brake balances brake effort to motor torque
by sensing the air pressure in the valve chest. This provides
precise control and eliminates back drop problems encountered
with some mechanical brakes. If the air supply is interrupted,
the pressure release causes instantaneous, automatic braking.
The new brake design is protected from impact by a cast housing
and is self-adjusting for the full life of the brake.
brake release kit.
Available as an accessory, this kit allows the operator to safely
lower a suspended load in the event of a power failure.
Planetary gearing system provides high torque capability by splitting
the torque path, thereby dividing and balancing the load over
more teeth. This assures longer life and reduced maintenance.
Strong yet lightweight for maximum portability and weather resistance.
