Q: How to improve anti-corrosion performance of elevator components for high temperature & sandstorm zones? What are supporting export solutions for Middle East & North Africa? A: The Middle East and North Africa feature year-round high temperature and heavy sandstorms. Ordinary elevator parts easily suffer rust, short circuits caused by sand entering circuit boards and aggravated traction machine wear within half a year. Export products require targeted upgrades for six core systems.

  1. Anti-corrosion and dustproof renovation for traction systems Motor housings adopt double-layer electrostatic plastic spraying anti-corrosion technology. Internal windings are coated with high-temperature resistant insulation. Fans are fitted with high-density dust filters, and bearings use high-temperature lubricating grease to avoid abnormal noise and jamming from sand intrusion.
  2. Sealing upgrade for electrical systems Control cabinets are upgraded to IP55 dustproof and waterproof grade with double rubber sealing strips on cabinet doors. Internal circuit boards are fully sealed with three-proof glue, and terminals are thick zinc-plated to prevent circuit erosion by sand and moisture.
  3. Improvement of metal parts for door systems Car and landing door frames are all made of 304 stainless steel, and door guide rails are galvanized. Internal door machine gears are covered with dust shields to avoid jamming caused by accumulated sand.
  4. Rust prevention for safety components Metal parts of governors, safety gears and buffers are hot-dip galvanized with increased thickness, and springs are coated with anti-corrosion paint. Outdoor shafts are equipped with dust-proof outer shells.
  5. Optimization of cabin and guide rail balance systems Dust sealing strips are installed on cabin gaps. Guide rails are made of hot-dip galvanized wear-resistant materials, and balance chains are wrapped with wear-resistant dustproof sleeves to block sand erosion.
  6. Complete foreign trade delivery solution Special desert elevator component kits are customized for Middle East and North Africa markets with full SASO certification documents. All complete elevators pass 72-hour simulated high-temperature sandstorm tests before delivery to reduce on-site failure rates for buyers.
