The 等D-D series safety brake is a high-power braking device used on low-speed shafts (drum shafts), which can be widely used for emergency safety braking of low-speed shafts in large and medium-sized cranes, port loading and unloading machinery, and boom lifting mechanisms. The working braking and emergency safety braking of mining winches, hoists, and high-power inclined belt conveyors, the safety braking of the driving mechanism of cable cars and cable cranes, and the safety (emergency) braking of the low-speed shaft of the lifting mechanism of special cranes such as casting cranes
Features of 等D-D series safety brake products: Normally closed design with good performanceTo produce disc spring force braking, a hydraulic drive release device needs to be installed separatelyThe action is sensitive and the closing (closing) time is shortOptional switches such as opening limit, pad wear, and excellent limit can be equipped for interlocking protection and fault display (when using PLC control)Stable performance with asbestos free hard friction lining, stable friction coefficient, no damage to brake discs, and insensitive to water medium and salt spray (seawater)Reasonable sealing structure design and purchased sealing components have good effects and long service lifeFlexible installation position, easy to use, adjust, and maintain
