Adopting proven spring braking and hydraulic release principles, it delivers stable braking torque, smooth operation, high-cycle working capacity and easy maintenance. Complying with German DIN and Chinese industrial standards, the brake features high standardization and universal compatibility.

Widely deployed in material handling, metallurgy, mining, construction and heavy transport machinery, it performs deceleration, parking and emergency safety braking functions. Equipped with optional automatic wear compensation, status monitoring switches and manual release devices, it enables precise, intelligent and safe braking control. Customizable explosion-proof and anti-corrosion versions are available to adapt to various harsh and complex working conditions.

 

 

1. Wide Industrial Application Range

This series brake is universally applicable to large special handling machinery, heavy-duty transportation equipment, metallurgical industrial equipment, mining machinery and construction engineering machinery. It serves three core functions: running deceleration braking, static parking braking and whole-machine safety protection, ensuring stable and reliable stop and limit control for heavy-load operating equipment.

2. Dual Standard Compliance for High Versatility

YPZ2 I, II, III types fully conform to German industrial standard DIN15435; YPZ2 IV, V, VI types comply with both DIN15435 and Chinese industry standard JB/T7020-2006. Dual-standard design ensures excellent interchangeability of parts, standardized installation dimensions and global universality, suitable for domestic and overseas complete machine supporting.

3. Stable Braking Performance & Adjustable Torque

The brake delivers highly reliable and consistent working performance with ultra-smooth braking action without impact or jitter. It supports high-frequency cyclic operation to adapt to continuous industrial production. Meanwhile, the braking torque is steplessly adjustable, allowing flexible parameter setting according to different load weights and working conditions to achieve accurate braking control.

4. Self-lubricating Hinge Structure, Low Maintenance

The main swing hinge is equipped with built-in high-efficiency self-lubricating bearings. The structural transmission resistance is low with high mechanical transmission efficiency. No regular grease filling and lubrication maintenance is required during the whole service cycle, which greatly reduces daily maintenance workload and operating cost.

5. Visible Torque Design for Convenient Adjustment

The braking spring is built inside the independent spring tube and matched with a professional torque indication rod. Users can directly observe the real-time braking torque value through the visual scale, realizing intuitive, fast and accurate torque adjustment, avoiding inaccurate braking caused by blind debugging.

6. Plug-in Non-asbestos Brake Pad, Safe & Efficient Replacement

Adopting advanced plug-in clamping type brake pad structure, the disassembly and replacement process is fast and convenient without disassembling the whole brake. The brake pad is made of high-quality non-asbestos environmentally friendly friction material, which features stable friction coefficient, high temperature resistance and wear resistance, ensuring safe, stable and pollution-free braking.

7. Interlocking Equal Back-distance Mechanism

Equipped with exclusive interlocking back-distance balancing device. During opening and closing actions, the mechanism can automatically keep the consistent back-distance of left and right brake pads. It effectively solves the common industry problem of single-side pad failure and non-fitting contact caused by uneven retraction, ensuring uniform stress and stable braking on both sides.

8. Delayed Braking Opening & Closing Control

Matched with dedicated hydraulic push rod device and lifting/lowering control valve group. By adjusting the valve group parameters, the brake can realize delayed opening or delayed closing action, which can buffer the starting impact and stopping inertia of heavy equipment, avoiding mechanical impact and prolonging the service life of the whole machine.

9. Diversified Optional Auxiliary Devices

The brake can be equipped with multiple optional accessories to expand functions according to user needs, realizing intelligent and automatic braking control, adapting to automated production line and remote monitoring working conditions.

10. Automatic Wear Compensation Device

The optional automatic compensation device can real-timely monitor the wear of brake lining. It realizes stepless automatic compensation of brake shoe back-distance and braking torque after friction material wear. It maintains constant braking performance for a long time without frequent manual adjustment, greatly improving equipment automation level.

11. Brake Gate Opening/Closing Display Switch

With working state feedback switch, it can output real-time electrical signals of brake normal opening and closing. It supports remote signal display and system interlock protection, which can effectively prevent equipment misoperation and realize linkage control with the host equipment.

12. Lining Wear Limit Switch

The wear limit monitoring switch can accurately sense the critical wear state of brake pads. When the friction lining wears to the limit value, it will automatically send alarm signals or trigger interlock protection, reminding users to replace accessories in time to eliminate potential braking failure risks.

13. Manual Release Device

Equipped with manual release mechanism. When the equipment is shut down for maintenance and power failure, workers can manually open the brake to release the locked state, facilitating equipment overhaul, debugging and manual jogging operation, improving maintenance convenience.

A: YPZ2 series brakes are widely used in heavy machinery scenarios including special handling equipment, heavy transportation machinery, metallurgical equipment, mining machinery and construction machinery. It undertakes three core functions: equipment deceleration braking, parking braking and safety emergency braking, which is the core safety supporting part of heavy industrial equipment.

Q2: What standards does the YPZ2 brake comply with? Is it suitable for export equipment?

A: YPZ2 I/II/III types comply with German DIN15435 standard; YPZ2 IV/V/VI types comply with both DIN15435 and JB/T7020-2006. With dual domestic and foreign standard certification, it has high dimensional interchangeability and performance universality, fully meeting the supporting requirements of export complete machines.

Q3: Does the brake need regular lubrication maintenance?

A: No regular lubrication is required. The key hinge position adopts self-lubricating bearing structure with high transmission efficiency and no daily oiling maintenance, which effectively reduces later operation and maintenance costs.

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

A: The interlocking equal back-distance mechanism can ensure synchronous retraction and consistent gap of the left and right brake pads. It avoids the hidden danger of braking failure caused by single-side pad jamming, non-separation or non-fitting, and ensures uniform and stable braking force on both sides.

Q5: What functions do the optional monitoring switches realize?

A: The opening/closing display switch feeds back the real-time brake working state for equipment interlock control; the wear limit switch monitors the lining abrasion in real time and sends an alarm when reaching the limit, which realizes intelligent early warning and avoids safety accidents caused by excessive wear.

Q6: What should I do if the working environment is humid, rainy or corrosive?

A: The standard version is only suitable for conventional environments. For outdoor rain and snow weather, high humidity or corrosive gas medium environment, you must select the customized anti-corrosion type brake; for flammable and explosive environments, explosion-proof customized products are required.

Q7: What working modes can the brake adapt to?

A: It supports S1 continuous long-term operation and S3-60% intermittent high-frequency cyclic operation, which can adapt to both long-term stable operation and frequent start-stop working conditions of industrial equipment.

Q8: Is the braking torque adjustable? How to adjust it?

A: The braking torque is steplessly adjustable. Equipped with a visual torque rod and scale, users can directly observe the torque value and complete accurate adjustment according to the actual load demand, with simple and intuitive operation.
