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.
