YW-L Series Electro-Hydraulic Drum Brake - YW-L200/E23

The YW-L200/E23 is a reliable medium-duty industrial drum brake belonging to the YW-L series, engineered for precise deceleration, load-holding, and emergency safety control of small-to-medium rotating machinery. Classified as a fail-safe, spring-engaged, electro-hydraulic released brake, it features a simplified yet robust structural design (the "L" denotes "lightweight and practical") with clear spring force adjustment and easy maintenance. The model designation (YW-L200/E23) clarifies its core parameters: "YW-L" for the practical-type electro-hydraulic drum brake series, "200" for the brake drum diameter (200 mm), and "E23" for the matched E-series electro-hydraulic thruster (providing release power). Widely used in general industry, logistics, and light heavy machinery, it ensures safe operation under loads of 150–600 tons and moderate working conditions (dust, normal temperature, and intermittent to continuous operation).

The YW-L series electro-hydraulic drum brakes, including the YW-L200/E23 model, have the following working principle and applications:

Working Principle

The YW-L series electro-hydraulic drum brake consists of components such as a brake arm, brake shoe, foundation frame, actuating lever, brake spring, and an electro-hydraulic thruster. Under normal conditions, the brake is in a closed state due to the action of the brake spring. The brake spring is located inside a square tube, and there is a scale outside the tube to display the spring force. This spring force can be adjusted by tightening the nut at the base of the spring.When the power supply is turned on, the electro-hydraulic thruster's motor is activated. Hydraulic pressure builds up in the thruster, and the piston is immediately actuated, which releases the brake. At this time, the brake shoe moves away from the brake drum, allowing the drum to rotate freely. When the power is cut off, the thruster motor stops, and the hydraulic pressure is released. The brake spring then pushes the thruster piston back, and the brake shoe clamps onto the brake drum, generating friction to achieve braking.

Applications

The YW-L200/E23 electro-hydraulic drum brake is widely used in various industrial fields:

Cranes: It is used to control the lifting and lowering of cranes, ensuring that the load can be accurately stopped at the required position.

Conveyors: In belt conveying systems, it can be used to stop or slow down the conveyor belt, facilitating the loading and unloading of materials and the maintenance of the conveyor system.

Winches: For winches in construction, mining, and other industries, the YW-L200/E23 brake can effectively control the winding and unwinding of the cable, ensuring the safety and stability of the winch operation.

Industrial Machinery: It is also applicable to various other industrial machinery, such as metallurgical equipment and building machinery, to provide reliable braking functions and ensure the normal operation and safety of the equipment.
