PEDESTAL/BARGE MOUNTED CRANES
Pedestal Mounted Crane
Also see ASME publication B30.8-2004, Floating Cranes
and Derricks.
Definition
A pedestal mounted crane is a crane which is securely
fastened to a foundation, barge, ship, or floating platform so
the crane is restrained from tipping.
Examples
1.
Crane rotating bed mounted on a turret (pedestal) which
is securely fastened to the foundation (Figure 2-6).
2.
Crane rotating bed mounted on a carbody (crawlers
removed) which is securely fastened to the foundation
(Figure 2-7).
WARNING
Overload Hazard!
A pedestal mounted crane will not tip to indicate to
operator that crane’s capacity has been exceeded. When
capacity of a pedestal mounted crane is exceeded, hook
rollers or other structural components may break, before
load lines fail, causing crane to separate from pedestal.
For this reason, great care must be taken to operate a
pedestal mounted crane within its rated capacity.
Careful planning is required before a crane can be
operated on a barge. Crane user shall verify that barge is
capable of limiting crane list and/or dynamics to maximum
allowable specified in Capacity Charts. If specified crane
list and/or dynamic conditions are exceeded, crane’s
capacity may be exceeded; hook rollers or other structural
components may break, causing crane to separate from
pedestal.
WARNING
Crane owner/user must verify that method used to fasten
or restrain crane to foundation, barge, ship or floating
platform is strong enough, under all operating conditions,
to prevent crane from breaking off foundation or moving
on barge.
Manitowoc does not permit use of a truck crane on a
barge, ship or floating platform.
