JD Neuhaus has supplied a BOP
handling system comprising
four air-operated monorail
hoists. This featured a centralised
pneumatic system providing
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 in common.

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

To accommodate the provision of
separate energy
chains in limited
space, the fitment of
individual energy
chains on both the
top and underside of
the support beam was
necessary. Each hoist has an
emergency lowering device for
the controlled, safe grounding
of suspended loads should
mains air power supply be
interrupted. Optional pendant
controls were provided for use
during equipment maintenance.
