Elevator Guide Shoe XAA380S1: Stable Guidance Core from Nanjing Zhuye Elevatorparts

Step-by-Step Usage Guide for Elevator Guide Shoe XAA380S1

1. Professional Installation & Commissioning

• Safety Preparation: Cut off the elevator’s main power supply and hang a “Maintenance in Progress—Do Not Power On” sign at the power switch. Fix the elevator car to a safe position using a safety clamp to prevent accidental movement. Locate the guide shoe installation position on the car frame and clean the area to remove dust, oil stains, and debris that may affect installation accuracy.
• Guide Shoe Installation: Fix the XAA380S1 guide shoe to the car frame’s preset mounting position using high-strength bolts provided by Nanjing Zhuye Elevatorparts. Ensure the guide shoe’s PU pad is closely attached to the guide rail, with no obvious gaps or deviations. Adjust the pressure plate of the guide shoe to control the contact pressure between the pad and the rail (standard pressure: 15–20N) to balance smooth movement and stable guidance. Tighten the bolts with a torque of 25–30 N·m to prevent loosening due to vibration.
• Calibration & Adjustment: After installation, manually push the car to move up and down along the guide rail to check for stuck or unsmooth movement. Use a feeler gauge to detect the gap between the PU pad and the guide rail (ensure it is within 0.3–0.5mm). If there is deviation, adjust the guide shoe’s position or pressure plate to ensure the car moves vertically without lateral shaking.
• Post-Installation Testing: Restore the power supply and conduct comprehensive functional tests. Operate the elevator to run at normal speed, inspection speed, and emergency speed to verify the guide shoe’s performance. Check the operation noise (normal value ≤ 55dB) and car stability (lateral deviation ≤ 2mm). If there is abnormal noise, shaking, or uneven movement, recheck the installation position and pressure adjustment immediately.

2. Daily Operation & Routine Inspection

• Daily Visual Inspection: During elevator maintenance, check the external state of the XAA380S1 guide shoe through the car inspection window or shaft inspection door. Ensure the aluminum alloy base is free of cracks, deformation, or corrosion; check the PU guide pad for wear, peeling, or hardening; confirm the fixing bolts are tight with no looseness.
• Weekly Functional Check: Operate the elevator to run up and down the entire shaft, and listen for abnormal noise (such as friction or collision sound) from the guide shoe area. Use a vibration tester to detect the car’s vibration amplitude (normal value ≤ 0.1mm). If there is abnormal noise or excessive vibration, inspect the guide shoe’s wear and rail contact status immediately.
• Monthly Parameter Monitoring: Measure the wear depth of the PU guide pad (normal wear ≤ 1mm per month). Check the contact pressure between the pad and the rail (use a pressure gauge to detect, ensure it remains 15–20N). If the pressure is insufficient or excessive, adjust the pressure plate in a timely manner.

3. Regular Maintenance Schedule

• Quarterly Maintenance: Disconnect the power supply, clean the guide shoe’s surface and the guide rail’s contact area with a dry, lint-free cloth to remove accumulated dust and oil stains. Apply a small amount of special guide rail lubricant (provided by Nanjing Zhuye Elevatorparts) to the contact surface of the PU pad to reduce wear and friction. Recheck the guide shoe’s fixing bolts and retighten if necessary.
• Semi-Annual Performance Test: Conduct a comprehensive performance test, including wear degree, load-bearing capacity, and buffering performance. Use a professional load tester to verify the guide shoe’s load-bearing capacity (ensure it meets the 20kN standard). For elevators in harsh environments (such as high humidity, high dust, or frequent full-load operation), increase the test frequency and check the guide rail for deformation that may affect the guide shoe’s performance.
• Annual Professional Overhaul: Arrange a professional inspection with Nanjing Zhuye Elevatorparts’ certified technical team. Disassemble the guide shoe to inspect the internal structure (such as springs and pressure plates) for aging or damage. Replace the worn PU pad with a genuine XAA380S1 pad. Conduct a full-range calibration of the elevator guiding system to ensure the guide shoe and guide rail operate in sync.

Recommended Replacement Cycle for Elevator Guide Shoe XAA380S1

1. Standard Replacement Cycle

2. Adjustments for Special Scenarios

• Harsh Environments: For elevators in high-humidity coastal areas (salt spray corrosion), high-dust construction sites, or elevators with frequent full-load operation (more than 1200 times per day), the replacement cycle of the entire guide shoe should be shortened to 1.5–2 years, and the PU pad should be replaced every 3–6 months. Harsh conditions accelerate the wear of the PU pad and corrosion of the aluminum alloy base, significantly reducing the guide shoe’s reliability.
• Low-Frequency Use Scenarios: For elevators with low usage frequency (e.g., villa elevators, small office buildings with daily running times < 200 times) and clean, stable environments, the replacement cycle of the entire guide shoe can be extended to 3–4 years, and the PU pad can be replaced every 12–18 months—only if Nanjing Zhuye’s professional inspection confirms that the guide shoe’s load-bearing capacity, wear degree, and guiding performance are all intact.

3. Immediate Replacement Conditions

• The wear depth of the PU guide pad exceeds 3mm, or the pad is severely peeled, cracked, or hardened, leading to abnormal noise or vibration during operation.
• The aluminum alloy base is cracked, deformed, or severely corroded, and cannot provide sufficient load-bearing capacity.
• After adjustment, the guide shoe still fails to ensure stable car operation, with lateral deviation exceeding 5mm or obvious shaking.
• The guide shoe’s fixing bolts are stripped or damaged, posing potential safety hazards of guide shoe detachment.
