초록 ▼

A power shovel comprising a body; a front end assembly mounted on the body including a dipper; means for crowding the dipper; means for hoisting the dipper; and an energy regeneration system including an energy storing means and means actuated by a predetermined movement of at least one component of the front end assembly for charging the energy storing means, the energy storing means providing in the loaded condition a force applicable to a component of the front end assembly for at least biasing such component toward a predetermined movement.

대표청구항 ▼

A power shovel comprising a body; a front end assembly mounted on said body including a stiffleg pivotally connected to said body, a dipper handle operatively connected to said stiffleg and a dipper operatively connected to said dipper handle; means mounted on said body and operatively connected to said front end assembly for hoisting said dipper; and means mounted on said body and operatively connected to said front end assembly for crowding said dipper; said crowding means including at least one fluid actuated, working piston and cylinder assembly operatively interconnecting said body and said front end assembly whereupon selectively supplying fluid under pressure to opposite ends of said cylinder, said front end assembly correspondingly will be caused to be lowered or raised, means for selectively supplying fluid under pressure to opposite ends of said cylinder, and an energy regeneration system including an energy storing means and means actuated by a predetermined movement of at least one component of said front end assembly for charging said energy storing means, said energy storing means providing in the charged condition a force applicable to a component of said front end assembly for biasing said component toward a predetermined movement wherein said crowd system includes a mast pivotally connected at a lower end thereof to said body and a connecting link pivotally connected at opposite ends thereof to said mast and said front end assembly; and wherein said working piston and cylinder assembly operatively interconnects said body and said mast.
