Abstract:
1. A mobile crushing system, comprising: a sub-construction having at least one chassis; a superstructure having at least one receiving hopper, a crusher, a transport device, and rigid bearings; and a hoisting device for raising and lowering said superstructure relative to said sub-construction disposed between said superstructure and said sub-construction, said hoisting device supported on said superstructure, said superstructure supported against said sub-construction by said hoisting device during traveling operation, and said superstructure can be placed on a ground by means of said rigid bearings by lowering said superstructure with said hoisting device during a crushing operation such that said rigid bearings at least partially transmit a weight of said superstructure along with dynamic and static forces acting on said superstructure directly onto the ground, said hoisting device completely decouples said superstructure from said sub-construction when said superstructure is in an operation position positioned on the ground.
