The ST-520 Electro-Hydraulic Thruster is designed to provide an 18 Kg (18 kgf) lifting force with a 51 mm stroke length for industrial brake applications. Powered by a 90-watt motor running on a 400/440V, 3-phase AC supply, it draws approximately 0.4 Amps. The unit utilizes around 2 liters of transformer oil as its working fluid, which is pressurized by an internal centrifugal impeller to drive the piston mechanism. Weighing about 6 Kg, its bi-directional radial blade impeller allows it to operate seamlessly in both clockwise and anticlockwise rotations, making it widely relied upon for heavy-duty material handling machinery and EOT crane braking systems.
