Elevator Brake Release Device HY-MRBP-22-B1 – Nanjing Zhuye Elevatorparts
The elevator brake release device, also known as the manual brake release tool, is a critical component in the elevator safety protection system. It enables maintenance personnel to manually release the elevator brake in emergency situations (such as power outages) or during maintenance, allowing the elevator car to be moved to a safe position. The Elevator Brake Release Device HY-MRBP-22-B1 launched by Nanjing Zhuye Elevatorparts is a high-reliability device tailored for mainstream elevator brake systems, widely compatible with renowned brands such as Schindler, OTIS, and KONE. It integrates precise mechanical transmission and ergonomic design, ensuring safe, efficient, and labor-saving brake release operations. Crafted with high-strength alloy steel and corrosion-resistant materials, this device strictly complies with international elevator safety standards (EN 81-20, GB 7588-2003), making it a trusted choice for global elevator maintenance teams and manufacturers.
Nanjing Zhuye Elevatorparts adheres to the “quality first, safety-oriented” principle, implementing strict quality control throughout the production process of the HY-MRBP-22-B1 elevator brake release device. Each unit undergoes rigorous testing, including mechanical strength verification, torque transmission accuracy testing, durability assessment, and corrosion resistance inspection. The device adopts a precision gear transmission structure, which can convert manual force into stable braking release torque, ensuring smooth operation without jamming. The handle is designed with anti-slip rubber, enhancing grip comfort and preventing hand slippage during operation. The key transmission components are treated with high-frequency quenching, significantly improving wear resistance and service life. The fully enclosed structural design effectively prevents dust and moisture intrusion, enabling stable performance in harsh environments such as elevator machine rooms and shafts.
Usage Guide for Elevator Brake Release Device HY-MRBP-22-B1
Correct use of the HY-MRBP-22-B1 elevator brake release device is crucial to ensuring the safety of maintenance personnel and elevator equipment. Nanjing Zhuye Elevatorparts strongly recommends that only certified elevator maintenance technicians perform brake release operations, as improper operation may lead to car sliding, resulting in serious safety accidents. Before use, maintenance personnel must receive professional training and fully understand the device’s working principle and operating procedures.
1. Pre-Use Preparation
First, confirm that the HY-MRBP-22-B1 brake release device matches the elevator brake model (check parameters such as interface size and torque range). Consult Nanjing Zhuye Elevatorparts’ technical team immediately if there is any uncertainty about compatibility. Then, cut off the elevator’s main power supply and lock the switch, placing a “Maintenance in Progress” warning sign at the elevator entrance and machine room door to prevent accidental operation by others. Confirm the elevator car’s approximate position through the control system or inspection hole, and ensure there are no obstacles in the shaft. Finally, check the device’s condition: inspect for cracks, deformation, or loose components; confirm the transmission mechanism is flexible without jamming; and prepare auxiliary tools such as a flashlight, communication device, and safety belt.
2. Correct Usage Steps
First, enter the elevator machine room and locate the brake device on the traction machine. According to the elevator’s maintenance manual, remove the brake’s protective cover to expose the brake release interface. Take the HY-MRBP-22-B1 device from Nanjing Zhuye Elevatorparts, and accurately connect its output end to the brake’s release interface, ensuring a firm and stable connection (do not connect reversely or loosely). Two maintenance personnel are required for the operation: one person holds the device handle and slowly rotates it in the specified direction (usually clockwise) to release the brake; the other person monitors the car’s movement through the inspection hole and communicates in real time. After the brake is released, slowly move the car to the nearest flat floor position using the manual traction device. After the car is in place, rotate the device handle in the opposite direction to reset the brake, and confirm the brake is reliably locked. Finally, disconnect the device from the brake, install the protective cover back, and clean the device and the surrounding area.
3. Daily Maintenance & Inspection
According to the “Elevator Maintenance Rules” (TSG T5002-2017) and Nanjing Zhuye’s recommendations, the HY-MRBP-22-B1 brake release device should be inspected monthly and undergo professional comprehensive testing annually. For daily maintenance: Clean the device’s surface and transmission components with a dry cloth to remove dust and debris—apply a small amount of high-temperature resistant lubricant to the rotating parts every 3 months (use the lubricant recommended by Nanjing Zhuye) to ensure flexible operation. Check for cracks, deformation, or wear on the device’s key components (such as gears and handles); replace damaged parts immediately. Store the device in a dedicated dry, ventilated toolbox after use, away from high temperature, humidity, and corrosive environments. Regularly verify the device’s compatibility and transmission accuracy with the matching elevator brake to ensure it can be used normally in emergencies.
Replacement Cycle of Elevator Brake Release Device HY-MRBP-22-B1
The replacement cycle of the HY-MRBP-22-B1 elevator brake release device is determined by usage frequency, storage environment, and component wear status. Under normal conditions (regular maintenance use, proper storage, no frequent collision or corrosion), Nanjing Zhuye Elevatorparts recommends a replacement cycle of 3-5 years. This cycle is based on long-term field operation data and component aging tests, fully considering the wear of mechanical transmission parts, attenuation of material strength, and degradation of anti-corrosion performance.
For elevators in high-traffic areas (e.g., large shopping malls, airports with frequent maintenance operations) or harsh storage environments (high humidity, heavy dust, or frequent vibration), the replacement cycle should be shortened to 2-3 years. High-frequency use accelerates the wear of gears and rotating parts, while harsh environments easily cause device corrosion and structural damage. For low-usage elevators (e.g., villa elevators, small office buildings with infrequent maintenance) and devices stored in ideal conditions, the cycle can be extended to 5-6 years, but annual professional testing by Nanjing Zhuye’s technicians is required to confirm that the device’s mechanical performance and transmission accuracy meet safety standards.
Replace the HY-MRBP-22-B1 brake release device immediately if any of the following issues occur, regardless of its service life: The transmission mechanism is stuck or cannot transmit torque normally, failing to release the brake; the device’s key components (gears, handles) are severely cracked, deformed, or worn; the device cannot be firmly connected to the brake interface; the device fails to pass the annual professional safety test; the device is dropped or collided violently, leading to potential structural damage. Timely replacement is critical to avoid failure to release the brake in emergencies, which may cause serious safety hazards.
The Elevator Brake Release Device HY-MRBP-22-B1 from Nanjing Zhuye Elevatorparts integrates high reliability, durability, and strong compatibility, providing a critical safety guarantee for elevator maintenance and emergency rescue. By following the correct usage, maintenance, and replacement guidelines, you can effectively ensure the device’s normal operation when needed, protecting the safety of maintenance personnel and elevator equipment. Choosing Nanjing Zhuye Elevatorparts means you get 100% authentic HY-MRBP-22-B1 devices, as well as professional services including model matching, use training, and timely after-sales support. Trust Nanjing Zhuye Elevatorparts for the safe and stable operation of your elevator.
