Adopting mature and optimized mechanical braking structures, it features stable operation, high safety reliability and convenient maintenance. Strictly manufactured in accordance with national and industry standards, this brake is widely applicable to various harsh industrial working conditions, providing precise deceleration, stable parking and emergency braking protection for mechanical equipment. It is an efficient, durable and cost-effective core safety component for hoisting, transportation and heavy industrial machinery.

Application Scope

This series of brakes is extensively applied in mechanical transmission systems of hoisting, transportation, metallurgy, mining, port, terminal, construction and other heavy industries, serving as a core device for equipment deceleration, normal parking and emergency braking to ensure safe and stable operation of mechanical equipment.

Core Performance & Structural Advantages

1. Standardized & Versatile Design: The mounting dimensions and braking torque parameters fully comply with the industry standard JB/ZQ4388-1997, and all technical specifications meet the requirements of JB/T6406-2006. With standardized and universal design indicators, the brake features strong compatibility and interchangeability, facilitating model selection, installation and standardized supporting application.

2. Stable & Durable Braking Performance: The product delivers safe and reliable braking performance with smooth and cushioning braking action. It can adapt to high-frequency cyclic operation for a long time without performance attenuation, maintaining consistent braking effect and greatly improving the continuous operation stability of equipment.

3. Maintenance-Free Hinge Structure: The main swing hinge is equipped with self-lubricating bearings, which effectively reduce mechanical friction resistance, improve transmission efficiency and extend the overall service life of the brake. No additional lubrication is required during daily operation, significantly reducing routine maintenance workload and operating costs.

4. Eco-Friendly & Easy-to-Replace Brake Components: The brake pads and brake segments adopt asbestos-free environmentally friendly materials, eliminating potential safety hazards caused by harmful substances. The card-mounted plug-in installation structure is adopted for brake components, enabling fast, convenient and labor-free replacement, which greatly improves maintenance efficiency and shortens equipment downtime.

5. Interlocking Equal Back-Distance Protection Device: Equipped with a dedicated interlocking back-distance adjustment mechanism, the device can always keep the back distance of the brake pads on both sides consistent during operation. It effectively avoids the common failure of unilateral brake pad separation from the brake wheel, eliminates potential braking dead zones and ensures balanced and reliable braking force on both sides.

1. Ambient Temperature: The applicable ambient temperature range is from -20℃ to 50℃, adapting to most conventional indoor and outdoor industrial operating environments.

2. Air Humidity: The relative humidity of the operating environment shall not exceed 90% to prevent component dampness, rust and electrical failure.

3. Altitude Adaptability: The altitude of the application site shall conform to the specification requirements of GB755-2008 to ensure stable mechanical and hydraulic braking performance.

4. Environmental Safety Requirements: The standard brake is applicable to conventional working environments without flammable, explosive or corrosive gases. For working sites with flammable, explosive, corrosive and other special media, customized explosion-proof or anti-corrosion models must be selected to meet safety production standards.

Q1: What industry standards does the YPZ2 series brake comply with?

A1: Its mounting dimensions and braking torque parameters conform to JB/ZQ4388-1997, and all technical performance specifications are in line with JB/T6406-2006. Meanwhile, its altitude adaptation requirements follow the national standard GB755-2008, ensuring standardized quality and universal compatibility.

Q2: Does the brake require regular lubrication maintenance?

A2: No regular lubrication is needed. The main swing hinge is fitted with self-lubricating bearings, which can maintain efficient transmission operation for a long time without manual oiling and lubrication, effectively reducing daily maintenance costs.

Q3: What are the advantages of the brake pad plug-in installation structure?

A3: Firstly, the brake pads adopt asbestos-free environmentally friendly materials with higher safety and environmental protection performance. Secondly, the card-mounted plug-in structure realizes quick disassembly and replacement of brake components, which is simple to operate, saves maintenance time and reduces equipment shutdown loss.

Q4: What is the function of the interlocking back-distance device?

A4: This core device keeps the back distance of the bilateral brake pads always equal during operation. It prevents the failure of unilateral brake pad separation from the brake wheel, avoids uneven braking force and potential braking failure risks, and ensures balanced, stable and reliable braking effect.

Q5: Can the standard brake be used in corrosive or explosive working environments?

A5: No. The standard YPZ2 brake is only suitable for conventional environments without flammable, explosive and corrosive gases. For special working conditions with corrosion, flammability and explosiveness, customized anti-corrosion or explosion-proof special models must be selected.

Q6: What is the applicable temperature range of the brake?

A6: The standard operating ambient temperature ranges from -20℃ to 50℃, which can adapt to most conventional industrial production scenarios.
