Traditional Traction - Passenger Lifts & Goods Lifts
A traction passenger lift operates through a traction machine that drives a sheave. Steel wire ropes pass over the sheave, connecting the car and counterweight. The friction (traction) between the ropes and sheave enables smooth vertical movement. The counterweight balances 40–50% of the rated load, significantly reducing motor power demand and improving energy efficiency.
Two main configurations:
Geared traction system – Suitable for low to mid-rise buildings, cost-effective and reliable.
Gearless traction system – Designed for high-rise applications, offering higher speed, lower noise, and superior ride comfort.
Our Core Technical Advantages
High Energy Efficiency
Counterweight balance and VVVF (Variable Voltage Variable Frequency) control optimize power consumption, reducing operating costs by up to 30% compared to hydraulic systems.
Smooth and Stable Operation
Advanced frequency conversion control ensures precise acceleration and deceleration curves, minimizing vibration and floor leveling error (±3 mm typical accuracy).
High-Speed Capability
Traction lifts can achieve speeds from 1.0 m/s to over 6.0 m/s, making them ideal for commercial towers, hotels, and residential high-rises.
Low Noise and Vibration
Gearless permanent magnet synchronous motors (PMSM) provide compact structure, reduced mechanical wear, and quieter operation.
Long Service Life
With proper maintenance, traction systems deliver extended durability due to reduced mechanical stress and balanced load distribution.
