ABSTRACT:
A power shovel comprises a boom which is supported on an undercarriage and can be lifted and lowered. A hydraulically operated shovel mechanism is mounted at a front end of the boom before pivoting about a horizontal axis. The shoveling mechanism carries a pivotable shovel and at least one cable pulley. A cable hoisting gear engaged with the boom is operable to move the boom. A cable of the cable hoisting gear is trained or reeved on the cable pulley of the shoveling mechanism so that the shoveling mechanism can be moved by the hoisting gear with movement of the boom.
