摘要

The dredger (10) and trailer (20) combination has the trailer connected via hydraulic couplings (30) to the hydraulic circuit of the hydraulic cylinder (16) of the pusher blade of the dredger. The flow in either direction of the hydraulic circuit can be switched to the hydraulic system of the trailer by switching valves (18).
