A cone crusher having a main frame, a crusher head interconnected with the main frame, a crusher bowl positioned adjacent to the first crusher member, and a double-acting hydraulic lift interconnected with both the main frame and the second crusher member. A force transfer member extends downward relative to the crusher bowl. The hydraulic lift includes an upper end interconnected with the main frame and a lower end interconnected with the force transfer member, thereby providing a downward clamp force on the force transfer member to compliantly clamp the crusher bowl to the main frame in an operating position. The hydraulic lift can provide an upward lift force on the force transfer member to move the second crusher member from the operating position to a clear position.

Hydraulic spring crusher

A power assist handle for providing control signals to a servo mechanism includes a spring-guided means of allowing motion of an input handle in only two directions in a configuration which has almost no friction between stationary and moving parts. Motion is sensed by a pair of Hall-effect sensors, each of which provides a signal output proportional to the displacement of the input handle in a respective orthogonal direction. The sensors and associated permanent magnets are arranged so that each is sensitive in one of the two directions and insensitive in the other.
