Carriage together with suspension gear for timber skidding

摘要

The invention relates to a carriage (1) together with suspension gear for timber skidding, with a carrying-rope clamp (2), mounted on the carriage, for a carrying rope (6) and a hauling-rope clamp (3), mounted on the carriage, for a hauling rope (7) continuous up to the load, the two clamps being actuated alternately in normal operation. According to the invention, provision is made for the carrying-rope clamp and hauling-rope clamp (2, 3) respectively to be actuated alternately by remote control, preferably by radio control. In one configuration, the invention relates to a hydraulic system for actuating the clamps of a carriage. The hydraulic system has a carrying-rope clamping circuit (30') and a hauling-rope clamping circuit (30'') which are each provided with an inflow valve (33', 33'') which can be connected to a pressure source (38, 21), a discharge valve (32', 32'') through which the pressure can be discharged into a pressureless tank (24), and a clamping cylinder (37', 37''). When the hydraulic system is changed over, before the line to the clamping cylinder now to be actuated is acted upon by pressure, the discharge valve located in this branch is closed and the discharge valve in the other branch is only opened when this other branch is cut off from the pressure supply (38, 21). <IMAGE>
