Steered vibrating roller for ground compacting - has hydraulic drive with solenoid valves for steering on difficult ground

摘要

The hydraulically steered road roller, especially a vibrating roller arrangement is remotely steered by radio link. The roller has two rollers held in a frame and driven by an engine with hydraulic transmission in the frame. These rolling rollers are steered and rotated about a vertical axis by a steering lever system. The steering system has a steering cylinder with solenoid valves. The steering system has a metal flap between two initiators connected to a conventional electronic circuit. A solenoid clutch is provided and the hydraulic system and the clutch are steered by wireless by a receiver (8) and actuating signals are transmitted by transmitter (7) in vehicle (1). This system actuates two rope and pulley connected roller assemblies (2, 3).
