JD Neuhaus supplies centralised pneumatic handling system for four hoists

MATERIALS handling specialists J D Neuhaus says it has recently supplied a BOP handling system comprising four of its air operated monorail hoists.

The equipment features a centralised pneumatic system to provide common sensitive controls for all the lift and traverse movements of the hoists either as individual or paired hoists, or with all four hoist units operating together.

The four "EH 50" model hoists each have a lifting capacity of 50 tonnes. Two hoists operate in tandem on one common overhead beam providing a collective synchronised lift of up to 100 tonnes, with two separate power supplies also provided for individual hoist operation when required.

To accommodate the provision of separate energy chains in the limited space available, the fitting of individual energy chains on both the top and underside of the support beam was necessary.

Each of the four individual hoists are also equipped with an emergency lowering device to handle the controlled and safe grounding of suspended loads in the event of any total loss or interruption of mains air power supply. The handling system operates off a six bar mains air pressure and is suitable for working in hazardous areas where there is a potential risk of explosion.
