The horizontally opposed dual-independent braking system of the D11 series stage electric hoist is the core design that ensures the safe and stable operation of the equipment. Its working principle is based on an ingenious layout and advanced braking mechanisms. In this system, two electromagnetic brakes adopt a unique opposed layout. One is installed on the front of the electric hoist, and the other is located on the back, with both precisely positioned on the central axis of the entire machine. This layout serves as the foundation for the efficient operation of the entire system. When the electric hoist is operating normally, the motor drives the gears, which in turn move the chain or wire rope to lift, lower, and handle goods.

Once the operation needs to be stopped, the two electromagnetic brakes play a crucial role. Thanks to the horizontally opposed layout, at the instant the electric hoist stops, the two electromagnetic brakes counteract the forces generated by the halt. To illustrate, just as a rope remains stable when the forces exerted by two teams in a tug-of-war are balanced, the opposing forces of the two brakes in this system significantly reduce the vibrations and noise generated when the hoist stops. This not only creates a quiet environment for stage performances but also extends the service life of the equipment. From the perspective of braking safety, the two electromagnetic brakes operate completely independently. This means that if one brake malfunctions, the other can still respond normally, braking quickly and smoothly to stop the electric hoist in a timely manner and prevent safety accidents caused by braking failures. For example, in sudden situations such as a short circuit in the electromagnetic coil of one brake, the other brake can immediately step in to ensure the safety of the equipment. Moreover, the independent operation enables faster response times. Compared with traditional single-brake or stacked dual-brake designs, the horizontally opposed dual-brake system can complete braking actions in a shorter time and with a smoother process, greatly enhancing braking safety and providing reliable protection for stage equipment hoisting and other operations.
