(Chapter 1) - TECHNICAL FEATURES

1.1 - GENERAL

In order to work, the lorry crane must be installed on a vehicle and, from this vehicle,
take  the  mechanical  power  it  needs.  It  follows  that  the  correct  performance    and
safety of the system depend on the installation.

It  is  important  to  note  that  the  capacities  given  on  the  plate  that  is  located  on  the
crane  are  intended  for  lifting  operations  carried  out  with  hook,  pallets  fork  and
buckets for loose material or any other device that doesn’t build up other tensions on
the structure the those of the hook itself.

Lifting  capacities  are  calculated  for  a  crane  servicing  the  vehicle  on  which  it  is
installed.

The use of the crane with the given lifting capacities is not permitted when the crane
is equipped  with: buckets, hearth moving,  magnets or any other equipment that can
cause to the crane stresses similar to those caused by the, here mentioned, devices.

Crane can not be used in explosive environment.

The crane is equipped with lifting eyes that make it possible to lift the crane by
respecting the gravity centre (picture 1). The crane shall be lifted with a proper lifting
beam equipped with chains and shakels in proportion with the crane weight.

The lifting points can bear the crane weight

only.
