Modern cranes are highly specialised pieces of
equipment. From the smaller truck mounted types
to the largest crawler cranes, the principles of lift
using rope sheaves remain a constant but the
applications of that principle vary per individual
application field. While many lift companies exist
and own equipment this segment is experiencing
an increase of rental companies purchasing
equipment and a decrease in owner-operators.
Operators chose to rent as needed in order to
keep costs down. This has a considerable impact
on the equipment: its operating time per year is
much higher than it used to be and the wear and
sliding parts of the machines are subject to harsh
conditions.
