ABSTRACT:
A hydraulic arrangement is provided for a spring support system. The hydraulic circuit arrangement includes a hydraulic cylinder, a hydraulic tank, a hydraulic conveying device, a hydraulic accumulator, a first selector valve arranged between the hydraulic accumulator and the hydraulic cylinder, a control implement with at least three switch positions, that include a lifting position, a lowering position and a neutral position for the hydraulic cylinder and a pipe break safety arrangement arranged between the control implement and the hydraulic cylinder. In order to permit the opening of the pipe break safety arrangement, a first control pressure line extends between the pipe break safety arrangement and a conveying device and first switching devices are arranged in the first control pressure line so that a control pressure can be applied to the first control pressure line by switching the first switching devices and the pipe break safety arrangement can be controlled to open.
