Use utmost care to crane up objects from under the water
・
When drawing up an object from under the water, the crane can
be subjected to almost the same load as when drawing it out of
the ground. Objects containing water may be far heavier than
estimated. When craning up an object from under water, always
perform it slowly so that the time for the water to escape from
the object will be left.
・
Do not attempt to draw up the object without pause. It will
become heavier as soon as it is drawn out of water because any
buoyancy no longer acts on it.
(6)
Proceed cautiously with compound operations
Compound operations combining winch hoisting and lowering,
slewing, and boom derricking and lowering will be slower than
the individual operations. When switching from compound to
single operation, work the controls slowly and smoothly with
no sudden changes of speed.
(7)
Addition of counterweights beyond the specification is
forbidden
If counterweights not included in the specification are added,
they put an unreasonable strain on the crane and may damage it.
When the load is removed, the excessive counterweight may
cause the crane to tip over to the rear. Never use counterweights
which do not conform to the specification.
(8)
Never remove the jib
Operating the crane with the jib removed compromises the
safety factor and could cause the crane to tip over. The lifting
capacity chart for boom operations is based on the assumption
that the jib is stowed on the boom. Therefore, never operate the
crane with the jib removed.
