Description

• High-Speed Safety: With a braking response time of ≤0.4 seconds, it effectively stops the 18ATF elevator during emergency situations, complying with EN 81-20 and ASME A17.1 safety standards.

• Heat Resistance: Ceramic friction pads resist high temperatures (up to 300°C) generated by high-speed braking, reducing wear by 40% compared to traditional metal pads.

• Perfect Compatibility: Its mounting holes, hydraulic 接口 (interfaces), and wiring ports align 100% with the 18ATF’s original brake assembly, eliminating the need for drilling or adapter modifications.

• Low Maintenance: A dust-proof and oil-proof seal covers the hydraulic system, preventing contamination from elevator shaft debris—reducing maintenance frequency by 50%.

1. Pre-Installation Preparation:

• • Execute the Lockout-Tagout (LOTO) procedure to shut down the 18ATF elevator and disconnect power to the brake system—prevent accidental activation.

• • Confirm compatibility: Use Nanjing Zhuye Elevator Parts’ free online compatibility tool (via their official website) to verify the TAB330AJ2 matches your 18ATF elevator’s serial number.

• • Gather tools: Torque wrench (with 10-30 N·m range), hydraulic pressure gauge, wire brush, and Nanjing Zhuye-recommended high-temperature hydraulic oil (ISO VG 46).

2. Removal of Old Brake:

• • Disconnect the hydraulic hoses and power cables from the old brake—label each connection with color-coded tags to avoid misalignment.

• • Use the torque wrench to remove the 4 mounting bolts (Otis-specified torque: 28 N·m).

• • Lift the old brake out of the assembly and clean the mounting surface with a wire brush to remove rust or hydraulic oil residue.

3. Installation of TAB330AJ2 Brake:

• • Apply a thin layer of anti-seize compound to the mounting bolts (avoid contact with friction pads).

• • Align the TAB330AJ2 brake with the 18ATF’s mounting bracket and tighten the bolts in a crisscross pattern (torque to 28 N·m).

• • Reconnect hydraulic hoses (ensure no leaks) and power cables—use the hydraulic pressure gauge to confirm system pressure is 15-20 MPa (as specified by Otis).

4. Calibration and Testing:

• • Adjust the brake clearance to 0.2-0.4 mm (using the TAB330AJ2’s built-in adjustment screw) to ensure smooth engagement.

• • Conduct a no-load test: Run the elevator at 50% speed and activate the brake—check for no abnormal noise and consistent stopping.

• • Perform a full-load test (with 1,600 kg simulated weight): Verify the brake stops the elevator within 1.5 meters (Otis’s 18ATF standard).

• • If issues arise (e.g., uneven braking), contact Nanjing Zhuye Elevator Parts’ technical support team for 24/7 troubleshooting.

5. Daily Operation Tips:

• • Facility managers should train operators to report squealing or grinding noises immediately—these indicate friction pad wear.

• • Avoid overloading the 18ATF elevator (max 1,600 kg) to prevent excessive brake stress.

• Normal Use (residential buildings, 10-14 hours daily operation): Replacement cycle of 3.5 to 5 years.

• High-Intensity Use (commercial towers, 20-24 hours daily operation, frequent full loads): Replacement cycle shortened to 2 to 3 years.

• Harsh Environments (coastal areas with salt spray, or elevators near factories with dust): Replacement cycle of 1.5 to 2.5 years.

• Friction pad thickness ≤2.5 mm (check via the TAB330AJ2’s inspection window).

• Brake activation delay >0.6 seconds (measured during maintenance tests).

• Hydraulic oil leaks (visible on hoses or the brake housing).

• The brake fails to hold the elevator in place on inclined guide rails (risk of drifting).

• Genuine Compatibility: Each TAB330AJ2 is manufactured to match the 18ATF’s original design, avoiding fitment issues common with generic brakes.

• Warranty and Support: A 2.5-year warranty covers defects, and free technical training is provided for maintenance teams.

• Fast Delivery: Global shipping takes 3-5 days for major markets (Europe, North America), ensuring minimal 18ATF downtime.
