Air-operated equipment for shipyards

Air operated lifting equipment from J D Neuhaus is used extensively in shipyards and in the offshore industries. The hoists and winches provide sensitive positioning controls with rugged, safe and reliable lifting capabilities.

Installing and disassembly procedures for propellers and drive shafts together with rudder blades and shafts have been routinely undertaken, together with lifting and removal of heavy equipment in engine rooms. An example has been the replacement of a 34t starboard propeller on the US aircraft carrier Enterprise. This operation was carried out underwater in Francisco Bay using three JDN Profi air hoists, each with a capacity of 50t. The JDN equipment has an Ex rating.

Equipment includes the Profi range of hoists with lifting capacities from 250kg to 100t. For lower load requirements, JDN mini air hoists are available, with load capacities from 125 to 1000kg. Air operated Profi winches for lift & pull operations can be supplied. These have capacities to 2000kg (lifter) and 3000kg (puller).

Hoists can be used for oblique lifting when special safety precautions are observed.
