J D Neuhaus launches hoists
The JDN company has introduced purpose-designed hoists suitable for subsea operation, incorporating uprated performance and sealing features to withstand continuous underwater operation, even at depths of 70 m. They can be supplied for either compressed air or hydraulic operation, utilising a diver-friendly pendant controller which is compatible with constricted, gloved-hand movements.

This controller is connected by standard length 2 m hoses to the hoist which ensures the aquanaut, hoist and load are all located within a close working environment. It is designed to ensure instantaneous and sensitive regulation of the hoist movements, providing infinitely variable speed of the load hook during both the raise and lower hoist operations. The need for voice instructions to/from a surface vessel or rig is obviated, eliminating potential delays or errors created through poor communications.
