Brakes & Couplings

Electro-Hydraulic Thrusters & Power Units
An electro-hydraulic thruster is a compact unit combining an electric motor, centrifugal pump and hydraulic cylinder: the actuator for drum and disc brakes, industrial valves, swivel (up to 90°) and clamping mechanisms. The Ed series complies with DIN 15430 and JB/T 10603-2006: 15 sizes from Ed23/5 to Ed630/12 with 220–6,300 N thrust, IP65, mounting at any angle within 0–180°, up to 2,000 cycles/h. ZED runs on 220 V DC or AC; BEd and BYT₁ are flameproof. The range also includes DYT electro-hydraulic pushers (up to 20,000 kgf, stroke up to 3,000 mm) and YZ(J) hydraulic power units for rail clamps and safety brakes.

Storm Brakes and Rail Clamps
Storm protection devices for rail-mounted cranes working outdoors at ports, wharfs and railways. YFX is an electro-hydraulic wedge brake: when power is cut, the Ed80/6 thruster with spring reset lowers a steel wedge onto the rail and the crane wheel (Ø350–800 mm) runs onto it; for the non-working state YFX is combined with anchoring devices and storm tie-downs. YLBZ is a wheel brake with a disc-spring hydraulic cylinder per GB/T 15622-2005: 50–180 kN clamping force, stainless steel fasteners and pins. YJGQ (160–600 kN) and XJYT (250 and 500 kN, 14 MPa) are hydraulic rail clamps.
