Title: Hydraulic control system for weighing and two-way valve therefor
Inventor: SMITH RONALD
IPC: G01G19/08
Filed: 1992-04-07
Abstract: A motion control system for hydraulically operated lifting devices. The system provides for the dynamic weighing of a loaded container by controllably directing hydraulic flow through a bypass chamber of a two-way valve. An analog output signal is generated by a hydraulic pressure transducer fluidly communicating with the two-way valve or by a tensiometer mounted on the arms of the lifting device. The two-way valve further provides a second bypass chamber which receives fluid under gravity from the lift circuit line of the hydraulic cylinder for controllably lowering the lifting device. The pressure transducer or tensiometer generate an analog signal proportionate to the weight being lowered and whereby the hydraulic fluid is returned to the reservoir of the hydraulic system independently and downstream of the main operating valve.
