Cable shovel
The
cable shovel is the ancestor of
hydraulic excavators. Created in the
19th century, the shovel cable was mounted on
rails and works with
steam. Then equipped with
tracks or
wheels, its use has declined in favour of
hydraulic excavators, which are easier to use and
maneuver.
Cable shovels are usually used on big
construction sites, especially in
mines and
dredging projects. They are, sometimes, called
dragline.
The
cable shovel is made of a
swiveling turret, an
arm and a
clamshell bucket activated by
cables. The lifting system resembles
track cranes but these cranes are more powerful and don’t have the same equipments.
