EdEd, BEd Series Electro-Hydraulic Thrusters
Electro-Hydraulic Thrusters ZHONGHAI Ed
An electro-hydraulic thruster is a compact unit of an electric motor, centrifugal pump and hydraulic cylinder that actuates drum and disc brakes, valves, gates, swivel (up to 90°) and clamping mechanisms. Ed is made with EMG (West Germany) technology to DIN 15430: short-stroke Ed23/5…Ed301/6 (220–3,000 N, stroke 40–60 mm) and long-stroke Ed50/12…Ed630/12 (up to 6,300 N, stroke 120 mm). Aluminium alloy housing, dry motor, IP65, mounting at any angle within 0–180°. Options: delay valves, springs, limit switches, heater. The explosion-protected version is BEd (Ex d I Mb, Ex d IIB T4 Gb).
