Pendulum chassis, in particular for a drill

摘要

Two oscillating cylinders (1) pivot the undercarriage units (81) relative to the chassis (80), with one cylinder assigned to each undercarriage unit. Hydraulic lines are arranged on the cylinders to actuate the cylinders and are connected to one another to pivot the undercarriage units in opposite directions. One hydraulic line for each cylinder has a safety device having a remote-controlled stop valve that blocks the respective line in case of line breakage. A remote-control device opens the stop valves during normal operation. An independent claim is included for a construction machine.
