💡 Key Features & Characteristics
Explosion-Proof & Hazardous Area Rated:
Drive Unit: The "B" in the model signifies that it is paired with an explosion-proof electro-hydraulic thruster (such as a BEd series). These thrusters feature a flameproof motor and junction box, making them safe for use in environments with flammable gases, vapors, or coal dust (e.g., underground mines, chemical plants).
Safety: Designed to strictly prevent any internal sparks or explosions from igniting the surrounding atmosphere.
Heavy-Duty Performance:
Massive Braking Capacity: With a 700 mm brake wheel and a powerful 2000 N thruster, this brake delivers exceptionally high braking torque, making it ideal for heavy-load machinery.
High Action Frequency: Capable of frequent braking operations, ensuring reliable performance in demanding, continuous-cycle applications.
Advanced Structural Design:
Self-Lubricating Bearings: The main swing hinge points are equipped with self-lubricating bearings. This ensures high transmission efficiency, a long service life, and eliminates the need for regular greasing or lubrication during use.
Equal Clearance Mechanism: Features an interlocking equal clearance device that automatically keeps the clearance between the brake shoes and the wheel perfectly even on both sides. This prevents one side from dragging or rubbing against the brake wheel.
Easy Maintenance: The brake pads (linings) use a secure, quick-release inserted or clipped structure. They are typically made of non-asbestos, semi-metallic, or other high-friction materials, making replacement fast, convenient, and environmentally friendly.
Intuitive Adjustment: The main brake spring is housed inside a spring tube, and a braking torque scale is provided on one side, allowing for convenient and precise adjustment of the braking force.
Robust Environmental Adaptability:
Designed to operate reliably in ambient temperatures ranging from -20°C to +50°C and in environments with up to 90% relative humidity.
🏭 Typical Applications
The YWZ5-700/B201 is essential for heavy machinery in hazardous and high-load environments:
Mining: Underground coal mine belt conveyors, heavy-duty hoists, and winches.
Port & Harbor: Large ship-to-shore cranes, RMGs, and bulk material handling equipment exposed to explosive dust.
Metallurgy & Steel Mills: Heavy overhead cranes, rolling mills, and other equipment operating near flammable gases.
Chemical Industry: Large valves, gates, and rotating machinery in refineries and chemical processing plants.

Note: The YWZ5-700/B201 is a highly specialized safety component. The "B" (Explosion-proof) designation is critical-ensure the specific explosion-proof rating (e.g., Ex d I Mb for coal mines) of the matched thruster aligns perfectly with the hazardous zone classification of your installation site. Due to its massive size and braking power, always verify that the equipment's foundation and shaft can withstand the reaction forces generated during emergency braking.
