Crane drives suit more varied applications

The air or hydraulic powered geared travel units from J D Neuhaus were designed for use with crane bridges and hoists, but have been used for driving wheeled bogeys running on floor mounted rails.

The air or hydraulic powered geared travel units in the J D Neuhaus range were designed for use with crane bridges and hoists.

They have, however, also been successfully used for driving wheeled bogeys running on floor mounted rails.

These applications would prove to be particularly useful where working practices result in restricted access to the services of an overhead travelling crane.

Rail mounted bogeys can efficiently move lighter loads between points of operation, so leaving additional time for the crane to undertake more productive heavier work.

Typical applications include metal fabricators and paper manufacturing plants, while the intrinsically safe air motor drive is ideal for use in potentially hazardous areas or poor working environments which includes feeding shot blasting machines.

The travel units incorporate a flanged motor for direct drive connection.

They also feature an integrated disc brake together with planetary gear.

Five models are available in the range providing various power, flange fixing and power take-off options.

The floor rail mounted bogeys are equipped for a single wheel drive of 0.7kW operating at 6 bar air pressure.

Air supply can be by cable reel, extendable cable chain or cable festoon with plug-in connection to a ring-main supply.

An emergency stop is incorporated on the drive which vents the airline to maintain safety by preventing wheel movement.

For more sophisticated operations, particularly over longer distances, radio control can be offered using a portable hand transmitter, which can be supplied as an explosion-proof version.

Electro magnetic valves can also be incorporated for fully automatic computer controlled operation, even where several units are involved.
