EH 125 lifting unit
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.
