Increased spark protection

A purpose-designed BOP handling
system comprising twin airoperated
monorail hoists, with a
joint lifting capacity of 200t has
been supplied by J D Neuhaus. The
hoists are a special compact design
which has been developed to suit
on-site operational requirements
and each hoist represents a 45%
reduction in
the horizontal
profile length
compared to
the JDN
standard EH-
100 product.

Running in
parallel on
two overhead
beams in
excess of 22m
in length,
both hoists incorporate two trolleys,
each with a 50t load rating,
providing a total 100t lift capacity
per hoist. Each hoist is also fitted
with a copper-coated bottom block
and clevis (providing increased
spark protection), together with a
galvanised chain box.

Both hoists incorporate overload
protection, with limit switches also
provided for the hoist and traverse
operations.
