Dive in with specialist chain ho

Air and hydraulic operated chain hoists from J D Neuhaus have been used to solve difficult underwater lifting and pulling operations for many years.

A recent typical subsea operation covered the removal, repair and eventual replacement of a damaged 50t rudder from a fully loaded bulk cargo vessel. The operation involved the underwater setting up and rigging of three air operated JDN Profi 25Ti hoists (offering 25t lift capacity each) to provide the necessary pulling and lifting power.

Now the company has invested in an R&D programme for the introduction of specialised handling products capable of undertaking subsea operations with minimum maintenance/repair afterwork.

Two hoists, the Profi 3Ti and 6Ti offering 3.2 and 6.3t lift capacities respectively, have been introduced as specialised subsea products. These incorporate high performance sealing qualities and include a purposed designed hand valve for easy operation by gloved divers.
