High Quality YW-E Series Two-step Electro-hydraulic Drum Brake

The YW-E series two-step electro-hydraulic drum brake is a two-stage braking device, and its working principle and usage are as follows:

Working Principle

First-stage Braking: When the brake is activated, the first-stage braking applies a relatively small and adjustable braking torque. This torque enables the deceleration of the mechanism in a stable manner, gradually reducing its speed.

Second-stage Braking: After the mechanism comes to a stop, the second-stage braking begins. It adds an additional braking torque, which can be adjusted within a specified range. This ensures a reliable holding brake or windproof brake, preventing the equipment from moving due to external forces such as wind. The start delay time of the second stage relative to the first stage can be adjusted through a one-way speed control valve in the damping cylinder circuit, with an adjustment range of 1-15 seconds.

Usage

Cranes: It is widely used in the traveling mechanisms of large and medium-sized outdoor cranes, such as the 大车运行机构 of gantry cranes and the lifting mechanisms of special cranes like foundry cranes. It provides excellent deceleration braking performance and ideal windproof braking effects, ensuring the safe operation of cranes.

Belt Conveyors: Applied to the working brakes of belt conveyors, it can effectively control the start and stop of the conveyor, ensuring the stable operation of the conveying system and preventing problems such as belt slipping or runaway.

Other Equipment: It is also suitable for equipment that requires controlled braking in ports, mining hoists, elevators, cable cars, and cable crane drives, such as port handling machinery and mine hoists, to achieve safe and reliable braking.

The YW-E Series Two-Step Electro-Hydraulic Drum Brake combines unique two-stage braking control, fail-safe reliability, and harsh-environment adaptability-making it a critical safety component for heavy-duty rotating machinery. Its smooth deceleration and firm holding capabilities address key industrial safety risks, ensuring productivity and personnel protection across ports, mining, metallurgy, and logistics sectors.
