The largest crane system
constructed to date by J D Neuhaus
has been delivered to Westcon
Lofteteknikk AS (WCL) of Norway
for use on an offshore drilling rig.

The semi portal design comprises
an A-frame supporting twin
overhead
horizontal track
beams providing
a 7.5m span.

The crane is
approximately
11.5m high with
a total weight of
32t. It is
equipped with
JDN hydraulic
EH 40-H
monorail hoists
operating on each of the twin
beams, each hoist providing an
individual lift capacity of 40t. These
hoists can be operated individually
or simultaneously from one control
and when used in conjunction, can
lift 80t to a height of 12m. A JDN
Profi 6 TI-H hoist with 6t lift
capacity also covers other
operational or service requirements.
