  • a guide element that guides the broken material onto the take-off conveyor preferably in the form of a curved deflection element, can be arranged on the movable crushing jaw of the jaw crusher, which thus takes part in the oscillating movement of the movable crushing jaw and thereby not only deflects the crushed material flowing out of the crusher discharge in the conveying direction of the discharge conveyor, but also takes it along in the conveying direction over a certain distance, so that no jams can occur in the transition area.
  • This arrangement is particularly recommended when the crushed material fed to the jaw crusher, e.g. Metal parts or reinforcement material, as is often the case when breaking concrete.
  • Different lifting drives can be used for the lifting device of the material feeding device.
  • at least one hydraulic lifting cylinder is preferably provided, which is supported on the chassis. The order is otherwise advantageously taken so that the crushed material feed device settles with its free end on a support arranged on the chassis when swiveling into its transport position, which can also be formed by the trigger conveyor.
