The Application of Load Sensing Systems on Articulated Manlift Vehicles

A new generation of truck mounted material handling aerial devices has been developed utilizing a Flow and Pressure On Demand hydraulic system. This concept provides critical multi-function control from both upper and lower operating stations. Safety control features are incorporated by utilizing logic elements to activate and dis-able control stations. Power density and hydraulic efficiency is increased by the use of an On Demand Pressure-flow compensated piston pump.
