YW SERIES CRANE THRUSTER BRAKES

Thruster Brakes are suitable for 380 Volts, 3 Phase A.C. supply for a wide range of drum sizes. Higher sizes can also be supplied against specific requirements. The brake is applied by the tension of the compressed springs mounted vertically between the thruster and brake lever. The thruster rods are connected with the brake by means of an angle lever. As the piston travels upwards the angle lever turns, pushes the brake rod and compresses the brake spring. Simultaneously, the brake lever on the other side of the wheel (Brake Drum) is retracted. The brake lever at the thruster begins to move when the first lever reaches the stop on the brake base member. The thruster and the brake are so adjusted as to reserve about 1/3 of the stroke for compensation of the wear of the brake linings.
