Princess Yachts is using freestanding
Goliath cranes from Street Crane
Company to produce its new 30 to
40m M Class tri-deck yachts at the
Devonport Dockyard. They will be
used in the assembly of the craft
allowing large fabrications to be
lifted, transported and accurately
placed as the yachts are fitted out.

The yard’s assembly facility is
enclosed by a lightweight, wide-span
space frame building. This has
insufficient strength to accommodate
overhead cranes, while freestanding
gantries would have occupied
production space. Street Crane
recommended floor running Goliath
cranes, using a slim leg design to
maximise hook coverage.

The main assembly area is served
by two mirror image Goliath cranes
of 16t SWL, each spanning 13.75m.

These have twin hoists of 8t lifting
capacity that can be used
independently or in tandem. A 28m
span Goliath crane, with hook
coverage over the whole production
area, has a single 16t hoist and will
share the outer running rail of the
smaller Goliaths.
