Shoe Brake Pusher Rod

     The main function of the thruster (usually referring to the electric hydraulic thruster) in a double beam crane is to drive the block brake to release or hold the brake, thereby controlling the braking and release of the lifting or operating mechanism. ‌‌
     When powered on, the thruster pushes the push rod through the hydraulic system, overcomes the force of the brake spring, releases the brake shoe, and allows the mechanism (such as the lifting drum, large/small car wheels) to operate freely;
     When the power is cut off, the push rod automatically returns to its original position under the action of spring force, tightly holding the brake wheel to achieve safe braking during power outage, preventing the hanging load from sliding down or the equipment from inertial sliding;
     Commonly equipped with electric hydraulic block brakes, used for lifting mechanisms (anti fall) and large/small vehicle operating mechanisms (anti slip vehicles), to ensure the safety and stability of frequent starting and stopping. ‌‌
     The thruster itself is not a power source, but an executing component of the braking system. Its core value lies in fast response, good buffering, and high safety, especially suitable for heavy-duty and frequently operated double beam crane scenarios. ‌‌
