New hoist range boosts capacity

JD Neuhaus has launched the Profi 75 TI and Profi 100 TI hoists, offering capacities of 75 and 100 tonnes, respectively.

The latest products, which incorporate savings in energy requirements as well as reductions in both weight and overall size dimensions, cover the demanding requirements of heavy engineering working conditions, according to the company.

The key component of these hoists is a new air motor unit, based on the J D Neuhaus motor-brake concept and incorporating a patented integrated brake system, with a stepped brake piston and a reliable self-lubricating rotor.

In the standard configuration of a 6 bar air pressure supply, the motor provides a 9kW power output, adequate for the operation of either hoist while still providing significant energy reductions.

At full nominal lift capacities (75 or 100t), the compressed air consumed is 7.6m3/min which represents in excess of 30% saving over the hoists being replaced. On lowering of full loads, the air consumed is 6m3/min, which represents an impressive full 50% saving over the power/energy consumption of the hoists being replaced.

The new hoists are designed with machinery group classification according to ISO 4301/FEM 9.5 II is M3/1Bm, which is good for 400 hours full load operation.

Although the overall air consumption has been reduced significantly, the lift and lower speeds with or without loads have been increased compared with the previous models of hoists, which helps to reduce handling and to increase production outputs over a full working day.

Existing products in the Profi range cover lift capacities up to 60t, ideally suited to mining engineering environments.
