Brake Driving Devices: YT1/BYT1 Thrusters, DYG Cylinders, YZ Power Units .

YT1, BYT1, DYG, YZ Series Brake Driving Devices

Driving devices for brakes and storm protection of cranes from the Driving Device section of the Zhonghai catalogue. YT1 thrusters (180–3,200 N, stroke 25–200 mm, 0.06–1.5 kW, IP54) and flameproof BYT1 (Ex d I, 127–1,140 V). DYG electro-hydraulic brake cylinders integrate a 550 W motor, hydraulic system and a cylinder with a 17–85 kN disc spring pack for SBD-DY brakes, wheel brakes and rail clamps. YZ hydraulic power units (10–20 MPa, 10–20 l/min, 2.2–7.5 kW) with accumulator and hand pump for release without power supply the pressure for SB/SBD safety brakes and YJGQ rail clamps.
