YFXYFX, DYLZ, DYJG, YJGQ, YLBZ Series Storm Brakes and Rail Clamps
Storm Brakes and Rail Clamps ZHONGHAI YFX

Storm protection devices for outdoor rail-mounted cranes: portal and gantry cranes, loading bridges in ports and on railways. The YFX storm wedge brake with an Ed80/6 thruster places a steel wedge under the crane wheel (Ø350–800 mm); holding force is 0.46 of the wheel load. DYLZ and YLBZ wheel brakes clamp the wheel with 50–180 kN. Rail clamps: hydraulic YJGQ (160–600 kN, QU70–QU150 rails, YZ1 power unit) and electro-hydraulic DYJG100 (200 kN). Limit switches for interlocking with the travel drive, hand release on YFX.
