Most Powerful Air Hoist Lifts 125 Tonnes

Nov. 7, 2011
Designed for heavy industrial and hazardous duty work, with minimal operating space
The new EH 125 lifting unit in the test stand. The six double-chain mechanism supplies a three-meter lift at speeds of 0.30 m/min with a full load, and 0.38 m/min on lowering.

J D NEUHAUS, a designer and builder of hoists and cranes, introduced what it calls the world’s first air-operated hoist with a lift capacity of 125 metric tons (137.5 short tons). The EH 125 monorail hoist is the most powerful unit in its EH range of handling equipment, and operates from a 6-bar air pressure and is equipped with 10-kW and 2.8-kW rated motors for the lifting and traverse functions, respectively.

In standard format, the hoist is supplied with a six double-chain mechanism that supplies a three-meter lift at speeds of 0.30 m/min with a full load, and 0.38 m/min on lowering. Horizontal travel speeds of 6 m/min are achieved with maximum load and 8 m/min when unloaded. A two-meter length flexible connection is supplied with an ergonomic multi-function pendant controller for precise, infinitely variable control of the lift/lowering and traverse operations for safe, accurate load placements.

The hoist is designed for heavy industrial applications, and its low-headroom design ensures that the hoist can be used where minimal operating space is available. Its Ex rating ensures the lift’s suitability for use in hazardous areas where there is a potential risk of explosion. The product is 100% duty rated, as well as insensitive to humid and dust-laden atmospheres. It can operate within a temperature range of -20°C to +70°C (-5°F to +160°F.)

Standard safety features include a fail-safe brake to hold the load in the event of air-supply failure; an emergency shut-off valve; and anti-climb and anti-drop devices, together with an emergency lowering device. Optional accessories include overload and increased spark protection, two-speed trolley travel control, and rack-and-pinion drive. Non-standard lift heights and remote radio-control operation can be accommodated.
