Mobile Hydraulic Component Test Stands


Mobile Hydraulic Component Test Stand


Entwistle's mobile hydraulic test stands accurately simulate normal hydraulic operating conditions in order to test aircraft systems. The units are true multi-output systems consisting of two or three high pressure hydraulic systems using a common reservoir. Each hydraulic system may be operated independently or simultaneously with the adjacent system. One system's operation has no affect on the adjacent system's performance. Each system contains independent controls, starter, valves, gauges, indicators, filter, pump, motor, outlet, and return connection. Diesel and electric powered units are available.
