Why
do stretching parts of cranes come in different shapes? What is
the purpose of a mesh arm ?
Cranes come in different sizes and
shapes. Some are compact and easy to more, and some are very big
and need to be assembled at the construction site. The small ones
with wheels such as rough terrain crane have a stretchable arm that
makes transportation easy. On the other hand, the big cranes that
get assembled at the construction site have mesh arms
in order to reduce its weight.
