路。A deceleration valve whose flow rate is controlled by a deceleration cam that operates in response to a descending signal from the lifting device.
A throttle valve is interposed in parallel with a flow path switching valve that operates in response to a lowering signal of the lifting device and a cylinder for driving the lifting device, so that a predetermined acceleration/deceleration is performed when the lifting device is lowered. Features a hydraulic circuit for driving lifting equipment.
