  • Mobile crusher
    Patent number: 5460332
    Abstract: A mobile crusher includes a caterpillar-type undercarriage and a chassis frame mounted on the undercarriage. A motor-driven crushing tool is mounted in the chassis frame. A hopper is connected to the chassis frame, so as to be swingable relative to the undercarriage about a horizontal axis. At least one conveyor for discharging crushed material from the crushing tool is connected to the chassis frame. A downwardly connected kingbolt which can be coupled to a coupling member of a tractor is attached to the underside of the hopper at a location remote from the horizontal axis of the chassis frame. A wheel unit with a plurality of wheels is connected to a conveyor frame which supports the conveyor.
