MLC165-1 OPERATOR MANUAL SAFETY INFORMATION
• For wire rope suspended platforms, the crane is
equipped with a hook latch that can be closed and
locked, eliminating the throat opening.
• The platform is properly attached and secure.
• Personnel platforms shall not be used in winds
exceeding 20 mph (9 m/s)
at the hoisted platform
height or in electric storms, snow, ice, sleet, or other
adverse
weather conditions which could affect the
safety of personnel
.
• Hoisting personnel within 20 ft (6 m) of a power line that
is up to 350 kV or within 50 ft (15 m) of a power line that
is over 350 kV is PROHIBITTED, except for work
covered in OSHA 29CFR1926 subpart V.
For operation outside the United States, the requirements of
the applicable national, state and local regulations and
safety codes shall be met. This may include, in addition to
the above:
• Automatic brakes such that when the equipment
operating controls are released, the motions are brought
to rest.
• A holding device (such as a load hold check valve) shall
be provided in the hydraulic or pneumatic systems to
prevent uncontrolled movement of the hoisting
equipment in the case of a system failure.
Manitowoc offers upgrade packages for friction controlled
models to install anti-two-block, dead man control, and
automatic hoist system control requirements to satisfy other
codes and standards.
Manitowoc recommends that cranes be properly maintained,
regularly inspected, and repaired as necessary. All safety
signs shall be in place and legible. We also urge Manitowoc
crane owners to upgrade their cranes with rated capacity
indicator/limiter systems for all lifting operations.

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.
WARNING
Overload Hazard!
A pedestal mounted crane will not tip to indicate to
operator that the 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 the crane to separate from
pedestal.
For this reason, great care shall 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
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
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 the
foundation or moving on the barge.
Manitowoc does not permit the use of a truck crane on a
barge, ship or floating platform.
