Ingersoll Rand "Liftchain" Air Hoists

Rugged, Compact and Lightweight in Construction

• All steel construct ion for better durability.
• Particularly adapted for difficu lt environments.
• Insensitive to dust and humidity. 100% duty cycle.
• Grade 80 calibrated load chain, corrosion resistant treated.

Precise Positioning

• Exclusive gear type air motor with high starting torque offering precise spotting capability.
• Infinitely variable speed control through pilot pendent or pull cha in control.

Safety

• Self adjusting automatic disc brake, fully enclosed for better protection - No maintenance required.
• Upper and lower limit switches, integrated in the hoist body for better protection. Allow the hoist to be also used in horizontal position.
• Overload protect ion device as standard on CE marked versions, (optional on all other versions).
• Main air emergency stop on pendent and built-in main air shut- off val ve on CE versions.

Versatility

• Numerous options available for adaptation to your application: chain conta iners (fabric or metallic material), rigid mounting trolleys (plain, geared or motorised), CE compl iant versions.
• Spark resistant hoists or hoist and trolley combinations are also available for use in explosive atmospheres, using solid bronze or bronze coated parts (see details in the "how to order").

Exclusive Gear Type Air Motor

• Better ability than other motors to accept contaminated air.
• High starting torque ensuring good spotting capability.
• Virtually maintenance free.
• Minimal moving parts.

Automatic Multi Disc Brake

• Fully enclosed for better protection and corrosion resistance.
• No adjustment requ ired . Maintenance free.
• Low pressure brake.
• "Venturi Effect" self-cleaning brake enclosure.

Infinitely Variable Speed Control

• Precision spotting control with infinitely variable speed through pilot pendent control or pull chain control.

Suitable for Hazardous Explosion Proof Environments

• Air motors (unlike electric motors) are inherently explosion proof.
• ATEX classification (as per directive EC 94/ 9/ EEC).
• Standard models are suitable for zone 2.
• Marking Ex II 3 GD c liB 135 ° C X.
• Optional spark protection package for zone 1.
• Marking EX II 2 GD c liB 135 ° C.

Overload Protection Device (Available for non-CE models)

• Hoist is shut off and brake sets when overload of 125 - 130% is detected.
• Superior durability compared to mechanical slip clutch which wears and generates damaging heat.
• Prevents high forces being applied to the hoist and the customer support structure.

Main Air Emergency Stop (Available for non-CE models)

Upper and Lower limit Switches

• Integrated in the hoist body for better protection.
• Allows the hoist to be also used in horizontal position.
• No adjustment required.

Reduced Maintenance

• Innovative modular concept allowing easy inspect ions and maintenance for major components.

Corrosion Resistant Load Chain

• Grade 80 calibrated load chain.
• Corrosion resistant treated for better protection and longer life.
• 5:1 design factor for safety and durability.

Improved Exhaust Muffler

• Easy cleaning and simple replacement.

Smart Design Bottom Blocks

• Bottom hook mounted on ball bearing for easier, smoother turn ing under load.
• Water drain hole to drain water from block.
• External lubrication point for better durability & ease of maintenance.
