YPZ2-630*30II/E121-R-MSK1 Series Electro-hydraulic Disc Brakes

YPZ2 - 630*30II/E121 - R - MSK1 is a high-performance electro-hydraulic arm disc brake of the YPZ2 series, which is widely used in heavy-duty industrial braking scenarios. Its model can be interpreted in detail by referring to the YPZ2 series model rules: YPZ2 is the series code of the electro-hydraulic disc brake; 630 refers to the brake disc diameter of 630mm; 30 represents the thickness of the brake disc is 30mm; II indicates the second type of the brake center height specification; E121 means it is equipped with an ED121/6 thruster; R stands for right-hand manual operation; MSK1 integrates functions such as automatic compensation of friction plate wear and limit switches. The detailed introduction is as follows:

Core Technical Specifications

Key Performance and Structural Advantages

High safety and reliability: It adopts the fail-safe principle. When the power is cut off, the thruster loses its thrust, and the brake spring exerts force to realize braking, which can prevent accidents caused by sudden power failure of the equipment. In addition, the enclosed spring tube can protect the internal spring from damage and pollution, ensuring the stability of the spring force.

Easy maintenance: The brake lining adopts a plug-in design, which is convenient and quick to replace when worn. The main hinge points are equipped with self-lubricating bearings, which have high transmission efficiency and long service life, and no additional lubrication is required during operation. Moreover, the wear self-compensation device can automatically compensate the brake shoe clearance, keeping the braking torque relatively constant and avoiding the trouble of frequent manual adjustment.

Stable braking effect: It is equipped with an interlocking shoe clearance balancing device and a shoe automatic alignment device, which can keep the clearance of the brake shoes on both sides equal at all times. This prevents one side of the brake lining from sticking to the brake disc and ensures uniform force on the brake disc, thus achieving a stable braking effect.

Convenient function expansion: The MSK1 functional module is configured. By adding various limit switches, it can feed back signals to the crane's PLC system to realize functions such as brake release, closing, and friction plate wear alarm, providing interlock protection for the safe operation of the main engine.

Typical Application ScenariosThis type of brake complies with DIN 15435 and JB/T 7020 - 2006 standards. It is mainly used for deceleration, parking braking and safety protection of various mechanisms. It is widely used in large-scale equipment in industries such as port loading and unloading, crane transportation, metallurgy and mining. For example, it can be matched with large gantry cranes, metallurgical continuous casting machines and mining hoisting equipment to ensure the safe and stable operation of the equipment.

Special Usage and Maintenance Notes

When the working environment temperature is lower than -20°C, the working fluid of the thruster should be replaced with YH-10 aviation hydraulic oil, or a heater should be installed on the thruster to avoid the hydraulic oil from freezing and affecting the normal operation of the thruster.

Regularly check the wear of the brake lining. When the wear reaches the limit, replace it in time to avoid reducing the braking torque. At the same time, inspect the tightness of the connecting parts such as the crossbar and brake arm to prevent loose parts from affecting the braking effect.

For equipment used in outdoor, coastal salt mist or metallurgical acid mist environments, anti-corrosion maintenance should be strengthened. It is recommended to choose customized anti-corrosion models to prolong the service life of the brake.
