Elevator Electric Brake Release Device EMK-EPB110: Safety Brake Core from Nanjing Zhuye Elevatorparts
Elevator Electric Brake Release Device EMK-EPB110 is a critical safety component designed for elevator traction systems, specifically engineered to control the opening and closing of the elevator’s mechanical brake. As the “safety switch” of the elevator’s braking system, it ensures the elevator brake engages reliably when stationary (preventing unintended movement) and releases smoothly when starting (enabling stable operation), while also providing emergency manual release functionality for maintenance or fault handling. Exclusively supplied by Nanjing Zhuye Elevatorparts (a professional and trusted distributor of high-quality elevator safety components), the Elevator Electric Brake Release Device EMK-EPB110 fully complies with international elevator safety standards (EN 81-20, GB 7588) and electrical safety regulations (IEC 61558). Featuring high reliability, fast response speed, and excellent compatibility, this device is widely applied in residential buildings, commercial complexes, office towers, hospitals, and industrial elevators worldwide.
Nanjing Zhuye Elevatorparts adheres to the core philosophy of “safety first, quality paramount” and implements strict quality control over the EMK-EPB110 Electric Brake Release Device. Each unit undergoes multi-stage pre-delivery inspections, including brake release performance testing, response time verification, electrical insulation detection, and long-term durability trials. The product adopts advanced electromagnetic control technology, a flame-retardant ABS shell (UL94 V0 rating), and a double-protection circuit design: the electromagnetic control module ensures fast brake release (response time ≤ 0.1s) and reliable engagement, with stable performance under voltage fluctuations; the flame-retardant shell and IP54 dustproof and waterproof rating adapt to the humid, dusty, and vibrating environment in elevator machine rooms; the double-protection circuit (overvoltage, overcurrent protection) prevents device damage caused by electrical faults. Its standardized wiring interfaces and mounting dimensions are tailored to most mainstream elevator traction machines, eliminating the need for complex modifications and enabling quick and safe installation.
Step-by-Step Usage Guide for Elevator Electric Brake Release Device EMK-EPB110
To ensure the reliable operation of the elevator’s braking system and extend the service life of the EMK-EPB110, follow the professional guidelines provided by Nanjing Zhuye Elevatorparts for installation, operation, and maintenance:
1. Professional Installation & Wiring
Installation must be performed by certified elevator technicians familiar with elevator traction and braking systems. Prior to installation, confirm the compatibility of the EMK-EPB110 with the target elevator’s brake type, rated voltage, and main control system using the detailed compatibility manual provided by Nanjing Zhuye Elevatorparts. The steps are as follows:
-
Safety Preparation: Cut off the elevator’s main power supply and the dedicated power supply of the traction machine. Fix the elevator car and counterweight to safe positions using safety clamps to prevent accidental movement. Clean the device mounting area (usually on the traction machine or near the brake assembly) to remove dust, oil stains, and debris that may affect installation and heat dissipation.
-
Device Installation: Fix the EMK-EPB110 to the dedicated mounting bracket using high-strength screws provided by Nanjing Zhuye Elevatorparts. Ensure the device is installed vertically (tilt angle ≤ 3°) and maintain a 15–20mm heat dissipation gap between adjacent components. Avoid installing it near high-temperature components (e.g., traction machine motor) to prevent overheating.
-
Wiring Operation: According to the elevator braking system wiring diagram, connect the device’s power terminal (rated voltage: 110VDC, consistent with the elevator brake power supply), control signal terminal (connected to the elevator main control system), and brake connection terminal (connected to the mechanical brake’s electromagnetic coil). Ensure correct polarity and tight wiring—use a torque wrench to confirm the tightening torque, and insulate the wiring joints with heat-shrinkable tubes to avoid short circuits. Clearly mark each wire to facilitate future maintenance and troubleshooting.
-
Post-Installation Testing: Restore the power supply and switch the elevator to inspection mode. Test the automatic brake release function: send a start signal via the main control system to confirm the EMK-EPB110 releases the brake smoothly (no abnormal noise) and the elevator moves stably. Test the automatic brake engagement function: stop the elevator to verify the brake engages reliably (the car remains stationary without sliding). Test the emergency manual release function: use the dedicated manual release lever (provided with the device) to manually release the brake, ensuring it operates smoothly and rebounds automatically after release. If there is delayed brake release, failure to engage, or abnormal noise, recheck the installation and wiring immediately.
2. Daily Operation & Routine Inspection
Regular inspections are crucial to early detection of device faults and ensuring elevator braking safety. Maintenance personnel should incorporate the following checks into their daily patrols:
-
Daily Visual Inspection: During machine room patrols, check the external condition of the EMK-EPB110. Ensure the shell is free of cracks, deformation, or discoloration (a sign of overheating); the power indicator and working status indicator (if equipped) are working normally; the wiring terminals are tight without looseness, oxidation, or burning marks; the manual release lever is intact and in the normal position.
-
Weekly Functional Check: Operate the elevator in inspection mode to test the brake release and engagement performance 5–10 times, ensuring smooth operation without jamming. Use a multimeter to detect the device’s input voltage and output current, ensuring they are within the rated range. Check the electrical insulation performance of the device (insulation resistance ≥ 10MΩ) to prevent leakage risks.
-
Monthly Cleaning & Maintenance: Turn off the power supply and clean the device’s shell, terminals, and ventilation holes with a dry, lint-free cloth or a professional electrical cleaner (avoid using corrosive agents). Inspect the wiring for aging or cracking (replace with genuine cables if necessary) and recheck all connections for tightness. Apply a small amount of anti-rust lubricant to the manual release lever’s rotating parts to ensure flexible operation.
3. Regular Maintenance Schedule
Systematic maintenance can effectively extend the service life of the EMK-EPB110 Electric Brake Release Device. Follow Nanjing Zhuye Elevatorparts’ recommended maintenance plan:
-
Quarterly Maintenance: Disconnect the power supply and remove the device from the mounting bracket. Thoroughly clean the internal components (if accessible) and connectors with a professional electrical cleaner to remove dust and oxide. Inspect the electromagnetic coil for signs of overheating or aging (e.g., discoloration, odor) and the circuit board for loose soldering points. Reinstall the device and recheck the wiring tightness and functional performance.
-
Semi-Annual Performance Test: Conduct a comprehensive performance test, including brake release response time, engagement reliability, and emergency manual release functionality. Use professional testing equipment to simulate voltage fluctuations (±10% of rated voltage) and electromagnetic interference to verify the device’s stable operation. For elevators in high-traffic areas or harsh environments, increase the test frequency to once every 3 months.
-
