Reduced profile handling

A BOP handling system comprising twin air-operated monorail hoists, with a joint lifting capacity of 200 tonnes has been released by J D Neuhaus. The hoists are a special compact design developed to suit on-site operational requirements with a 45% reduction in the horizontal profile length compared to the JDN standard EH-100.

The hoists run in parallel on two overhead beams in excess of 22 metres in length. Both incorporate two trolleys, each with a 50 tonne load rating, providing a total 100 tonne lift capacity per hoist. Each is also fitted with a copper-coated bottom block and clevis (providing increased spark protection), together with a galvanised chain box. The overhead support beams incorporate a rack and pinion drive for the trolleys, ensuring that even inclines up to 2.5° can be negotiated.
