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 that is securely
fastened to a foundation, barge, ship, or floating platform so
that the crane is restrained from tipping.
Examples
• Figure 2-5 illustrates a crane rotating bed mounted on a
turret (pedestal) that is securely fastened to the
foundation.
• Figure 2-6
illustrates a crane rotating bed mounted on a
carbody (crawlers removed) that is securely fastened to
the foundation.
WARNING
Overload Hazard!
A pedestal-mounted crane will not tip to indicate to the
operator that crane’s capacity has been exceeded. When
a pedestal-mounted crane’s is exceeded, hook rollers or
other structural components may break, before load lines
fail, causing the crane to separate from the 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. The crane user shall verify that the
barge is capable of limiting crane list and/or dynamics to
maximum allowable specified in capacity charts. If the
specified crane list and/or dynamic conditions are
exceeded, the crane’s capacity may be exceeded. Hook
rollers or other structural components may break, causing
the crane to separate from the pedestal.
WARNING
Tipping Crane Hazard!
The crane owner/user shall verify that the method used to
fasten or restrain the crane to the foundation, barge, ship
or floating platform is strong enough, under all operating
conditions, to prevent the crane from breaking off from the
foundation or moving on the barge.
Manitowoc Cranes does not permit the use of a truck
crane on a barge, ship, or floating platform.
