💡 Key Features & Characteristics
Explosion-Proof & Safety Certified:
Flameproof Thruster: The core driving component is a fully enclosed, explosion-proof electro-hydraulic thruster. It is engineered to contain any internal explosion and prevent it from igniting the surrounding hazardous atmosphere.
Hazardous Area Compliance: Designed for environments with flammable or explosive gases (such as petrochemical plants) and typically carries strict safety certifications (like the MA mark for mining applications or Exd standards for industrial gas atmospheres).
High-Performance Specifications (YWZ5-600/B201):
Brake Wheel Diameter: Designed for a massive 600 mm brake wheel.
Driving Thrust: Powered by a B201 explosion-proof thruster delivering 20,100 N of linear force.
Power Supply: Operates on standard industrial 3-phase AC power, typically 380V at 50Hz (custom voltages like 660V or 1140V are often available for specific hazardous zones).
Duty Cycle: Capable of continuous operation (S1) or frequent intermittent duty (S3-60%), making it highly suitable for demanding, repetitive braking cycles.
Advanced Mechanical Design:
Fail-Safe Operation: Operates on a "power-to-release, spring-to-brake" principle. When powered, the thruster pushes the brake shoes open. Upon power loss, heavy-duty springs instantly clamp the shoes onto the wheel for emergency stopping.
Equal Clearance Mechanism: Features an interlocking linkage system that automatically keeps the clearance between the brake shoes and the wheel perfectly even on both sides, preventing uneven wear or dragging.
Self-Lubricating Bearings: The main pivot points are equipped with self-lubricating bearings, ensuring high transmission efficiency and a long, maintenance-free service life.
Quick-Change Linings: The brake pads (linings) use a secure, clip-on insert structure. They are available in various materials (including non-asbestos semi-metallic options) and can be replaced quickly and safely.
Visible Torque Adjustment: The main brake spring is housed in a tube with a clear external scale, allowing maintenance personnel to easily read and precisely adjust the braking torque without complex calculations.
Environmental Adaptability:
Designed to operate reliably in ambient temperatures ranging from -20°C to +50°C and in environments with relative humidity up to 90%.
🏭 Typical Applications
The YWZ5-600/B201 is a mission-critical safety component used across various heavy industries with hazardous conditions:
Mining & Coal Processing: Used as the primary service and safety brake for underground belt conveyors, mine hoists, and winding engines where methane gas and coal dust are present.
Oil & Gas / Petrochemical: Ideal for operating braking mechanisms on large cranes, winches, and emergency shutdown systems in refineries, chemical plants, and offshore platforms.
Metallurgy & Heavy Industry: Applied in steel mills and foundries where industrial gases or combustible dust create explosive working environments requiring massive, reliable braking torque.
