Elevator Slide Hall Door Slide: Smooth Guidance Core from Nanjing Zhuye Elevatorparts

Step-by-Step Usage Guide for Elevator Slide Hall Door Slide

1. Professional Selection & Installation

• Safety Preparation: Cut off the elevator’s main power supply and lock the power switch to prevent accidental power-on. Fix the elevator car to a non-working floor with mechanical supports to avoid interference with hall door operation. Use a door holder to fix the hall door leaf in the fully open position.
• Old Slide Removal: Locate the slide installation position (both sides of the hall door frame, guiding the door leaf sliding). Remove the fixing bolts connecting the old slide to the door frame, and take down the old slide. Clean the mounting surface of the door frame to remove dust, oil stains, and rust, ensuring the surface is flat and dry.
• New Slide Installation: Take the new Elevator Slide Hall Door Slide from Nanjing Zhuye Elevatorparts, and place it on the cleaned mounting surface. Adjust the slide’s horizontal and vertical positions to ensure it is parallel to the door opening direction (parallelism deviation ≤ 0.5mm) and perpendicular to the door frame (perpendicularity deviation ≤ 0.3mm). Fix the slide to the door frame using high-strength bolts provided by Nanjing Zhuye Elevatorparts, and tighten the bolts evenly to avoid deformation caused by uneven force.
• Door Leaf Assembly: Connect the hall door leaf’s sliding shoes to the new slide. Ensure the sliding shoes fit closely with the slide (clearance 0.1–0.3mm) and can slide freely without jamming. Adjust the position of the sliding shoes to make the door leaf parallel to the slide and evenly stressed on both sides.

2. Adjustment & Function Test

• Smoothness Adjustment: Manually push the hall door leaf to slide back and forth, feeling for resistance or jitter. If there is uneven resistance, adjust the sliding shoes’ position or the slide’s installation angle until the door slides smoothly with uniform force.
• Parallelism & Sealing Test: Check the parallelism between the door leaf and the slide during sliding—ensure no deviation or tilting. Close the hall door and check the sealing performance between the door leaves and between the door leaf and the door frame (gap ≤ 3mm). Adjust the slide’s position if the gap is uneven.
• Operational Noise Test: Switch the elevator to inspection mode and test the hall door’s automatic opening and closing. The operating noise should be ≤ 55dB; if there is abnormal friction noise, check if the slide surface is smooth or if the sliding shoes are worn, and handle accordingly.

3. Daily Operation & Routine Maintenance

• Daily Visual Inspection: During elevator patrols, check the external condition of the slide. Ensure the slide surface is smooth without scratches, wear, or rust; the fixing bolts are tight without looseness; the sliding shoes are intact without excessive wear. Observe the hall door’s sliding status—abnormal phenomena such as jamming, slow sliding, or tilting may indicate slide faults.
• Weekly Lubrication & Cleaning: Clean the slide surface with a soft, dry cloth to remove dust and debris. Apply a thin layer of special lubricating grease (recommended by Nanjing Zhuye Elevatorparts) to the slide’s guiding surface to reduce friction between the slide and sliding shoes. Avoid using excessive lubricant to prevent dust accumulation.
• Monthly Precision Check: Use a level and feeler gauge to check the slide’s horizontal/vertical accuracy and the clearance between the slide and sliding shoes. If the accuracy exceeds the standard or the clearance is too large (＞0.5mm), adjust the slide’s position or replace the sliding shoes in time. Check the slide’s load-bearing status and ensure no deformation.

Recommended Replacement Cycle for Elevator Slide Hall Door Slide

1. Standard Replacement Cycle

2. Adjustments for Special Scenarios

• Harsh Environments & High-Traffic Scenarios: For elevators in high-humidity coastal areas (salt spray corrosion), high-dust industrial sites, or ultra-high-traffic locations (e.g., large airports, central shopping malls) with daily hall door cycles ≥ 3500, the replacement cycle should be shortened to 4–5 years. Harsh conditions and frequent use accelerate the slide’s wear and corrosion, significantly reducing its reliability.
• Low-Frequency Use Scenarios: For elevators with low usage frequency (e.g., villa elevators, small office buildings with daily operation time < 8 hours) and stable environments (constant temperature and humidity), the replacement cycle can be extended to 8–10 years—only if Nanjing Zhuye Elevatorparts’ professional technicians conduct an inspection and confirm that the slide’s dimensional accuracy, surface smoothness, and load-bearing capacity meet the original factory standards.

3. Immediate Replacement Conditions

• The slide surface is severely worn (wear depth ＞0.5mm) or has obvious scratches, causing the hall door to slide unevenly or jam frequently.
• The slide is deformed or bent, leading to the hall door leaf tilting, unable to close tightly, or having excessive gaps.
• The slide is severely rusted (rust coverage ＞30%), and the rust cannot be removed, threatening the structural strength and guiding precision.
• Professional testing confirms that the slide’s parallelism or perpendicularity deviation exceeds 1mm, and the problem cannot be resolved by adjustment, affecting the normal operation of the hall door.
