ABSTRACT:
A hydraulic bypass control system for tapping off the lift circuit of a hydraulically operated lifting device. The bypass control system slowly releases hydraulic fluid from the lift circuit and directs it back to the reservoir in a controlled manner so a load is smoothly moved from a reference position to a weighing position. Reliable weighing may be obtained by avoiding dynamic shaking, vibration and pressure surges, which permits the weighing step to be reliably made at the same point or range and affords precise calibration of a load transducer with a weighing instrument to be made.
