Top China Elevator Modernization Kit Manufacturer & Factories

Ascom Elevator is recognized as a pioneering force and premier elevator modernization kit manufacturer and supplier in China, delivering cutting-edge Fuji Lifts & Elevators. Operating in an increasingly vertical world, our comprehensive capabilities cover Passenger elevators, Home elevators, Panoramic sightseeing elevators, Cargo elevators, Escalators, and Shopping cart escalators. Through structured OEM/ODM manufacturing processes, we formulate turnkey upgrade kits that systematically restore obsolete units, improving safety parameters and operating parameters to align with modern international metrics.

The decision to modernize aging vertical transportation systems rather than pursuing full replacements is driven by financial and architectural necessities. In dense urban nodes globally, the structural integration of old elevator shafts limits the capacity to install brand-new structural components without committing to extensive demolition. Modernization kits alleviate these constraints by retaining the core structural elements of the lift—such as well-built car frames, guide rails, and counterweights—while completely overhauling the electronic brains (microprocessor-based controller cabinets), drive assemblies (VVVF technology), and safety gear mechanisms.

By leveraging Ascom Elevator’s proprietary design technologies, facility managers can optimize lifecycle returns, diminish power consumption profiles by up to 45%, and achieve absolute adherence to EN 81-80 (Safety rules for existing lifts) and ASME A17.3 codes. Ascom’s operations are designed to balance technological innovation with cost-efficiency, ensuring our clients receive high-performance engineering upgrades suited to their exact architectural needs.

Technical Architecture of High-Reliability Modernization Kits

A high-performance elevator modernization kit is not merely a collection of spare parts; it is an integrated system designed to run as a unified mechanical and electrical system. The major subsystems of Ascom’s modernization kit include:

• Integrated Control Cabinet (The Electronic Brain): Equipped with a dual 32-bit microprocessor control system and parallel/serial communications (CAN-bus architecture). This architecture minimizes building cabling and reduces electrical noise, providing millisecond-level reaction times for control safety circuits.
• Permanent Magnet Synchronous Gearless Traction Machine: Converting old geared traction drives to gearless permanent magnet technology. This provides a direct power saving of up to 40-50% while decreasing mechanical friction, heat generation, and transmission wear. Noise levels are kept below 48dB in the shaft and machine room.
• VVVF Variable Frequency Door Operators: Upgrading older mechanical belt-driven doors to closed-loop VVVF systems with integrated encoder feedback. This ensures speed control curves adapt to dust build-up, and includes 3D infrared light curtain arrays to prevent passenger injuries.
• Energy Regenerative Unit: Converting gravitational potential energy (under heavy load downward travel or light load upward travel) back into pure, harmonic-compliant AC electrical current, feeding it directly back into the building’s power grid.

Localized Application Scenarios & Mechanical Integration

Elevator modernization requirements vary depending on building use and geographical demands. Ascom constructs dedicated packages optimized for these scenarios:

1. High-Density Commercial Offices: For office environments, modernization focuses on reducing waiting intervals and transit times. Our systems feature Destination Control Systems (DCS) where passengers group their destinations before entering, optimizing passenger flow and minimizing unnecessary stops. The mechanical upgrade includes replacing standard geared motors with high-speed (up to 4.0m/s) PM gearless machines, improving traffic handling capacity by 35% without requiring shaft alterations.

2. Healthcare Facilities & Hospitals: Hospital stretcher and bed lifts require smooth travel and precise leveling. Upgraded systems feature continuous-feedback accelerometers and specialized passenger-load logic to ensure smooth transitions between acceleration, cruise speed, and deceleration phases. Interior finishes use anti-bacterial materials, and safety systems include power backup functionality to drive the car to the nearest floor during power failures.

3. Heavy Industrial Warehouses: Industrial freight applications prioritize load integrity and leveling reliability under heavy stress. Modernizing these systems requires heavy-duty guide-shoe integrations, solid safety-gear frameworks, and robust hydraulic valves capable of managing eccentric loads from forklifts. Ascom's cargo modernization kits include structural reinforcement plans alongside heavy-duty VVVF drives to manage initial start-up torque demands.

Technological Roadmap & Future Outlook

The industry is transitioning toward digital integration and predictive maintenance. Ascom’s research and development roadmap focuses on these key areas:

Supply Chain Resilience & Chinese Manufacturing Advantages

China is a hub for global precision engineering and elevator manufacturing. The concentrated industrial clusters in the Yangtze and Pearl River Deltas provide direct access to high-grade silicon steel, precision copper windings, and advanced cast iron. This localized supply chain allows Ascom to source premium materials efficiently, keeping production costs competitive.

By streamlining component procurement and logistics, Ascom shortens production lead times compared to Western manufacturers. Every modernization kit undergoes testing on simulator rigs under varying load simulations to verify electrical and mechanical performance before shipment. This rigorous approach helps maintain high product reliability and consistent performance across global markets.

Regulatory Compliance, Safety Codes, and Localized Support

Global markets require adherence to specific safety standards. Ascom designs modernization kits to comply with major international codes:

• Europe: Compliance with EN 81-20/50 for passenger lifts and EN 81-80 for improving the safety of existing systems.
• North America: Adherence to ASME A17.1 / CSA B44 safety codes for elevators and escalators, including seismic mitigation requirements.
• Oceania & Asia: Compliance with AS1735 and local national frameworks.

We work closely with local engineering partners to supply site-specific documentation, wiring schematics, and calculation files. This structured support helps ensure field installations receive compliance approvals from local regulatory bodies, reducing project delays.
