ABSTRACT:
A hydraulic by-pass control system is provided in the hydraulically operated lift assembly of a loader which uses double-acting hydraulic cylinders. The by-pass control system provides a low-resistance alternative pathway between the lowering circuit of the lift assembly and the hydraulic fluid tank. Accurate weighing measurement of the load on the lifting arms of the loader may be achieved by temporarily opening the alternative low-resistance pathway, thereby effectively converting the hydraulic circuit to a single-acting configuration during the taking of load cell signal measurements of back-pressure in the lift circuit.
