摘要: A motion control system for hydraulically operated lifting devices. The provides the dynamic weighing of a loaded container by controllably directing hydraulic flow through bypass chamber (51) two-way valve (42). An analog output signal is generated pressure transducer (53) fluidly communicating with or tensiometer (24) mounted on arms device (14). (42) further second (54) which receives fluid under gravity from lift circuit line (40) cylinder (18) lowering generate an proportionate to weight being lowered and whereby returned reservoir independently downstream main operating (33).
