Abstract
A hydraulic circuit for supplying fluid to a ram to move an elongated member about a fixed axis on a frame includes a reservoir, pump, valve and conduits connected to opposite ends of the fluid ram. The fluid ram includes a cylinder pivoted on a ram pivot on the frame adjacent to and outside the fixed axis and the elongated axis of the member is moved across the ram pivot as the member is moved between working and transport positions. The hydraulic circuit incorporates a valve element carried by the piston and moved from a seated position at the critical time when the elongated axis is generally coincident with the ram axis to interconnect the two cylinder chambers and assist in moving the axis across the ram axis.
