A BOP handling system comprising
twin air-operated monorail hoists,
with a joint lifting capacity of 200
tonnes has been released by J D
Neuhaus. The hoists are a special
compact design developed to suit
on-site operational requirements
with a 45% reduction in the
horizontal profile length compared
to the JDN standard EH-100.

The hoists run in parallel on two
overhead beams in excess of 22
metres in length. Both incorporate
two trolleys, each with a 50 tonne
load rating, providing a total 100
tonne lift capacity per hoist. Each is
also fitted with a copper-coated
bottom block and clevis (providing
increased spark protection), together
with a galvanised chain box. The
overhead support beams incorporate
a rack and pinion drive for the
trolleys, ensuring that even inclines
up to 2.5° can be negotiated.
