Counterweight rollers (also known as counterweight wheels) are roller devices installed at the bottom or top of the counterweight frame. Their main function is to support the counterweight and reduce friction between it and the guide rails, assisting the counterweight to run synchronously with the car and balancing the car's weight to reduce the load on the traction machine.

1. Structure and Materials

2. Functions and Roles

• Load-bearing and Guiding: The counterweight is a balancing device for the elevator (its weight is approximately 40%-50% of the car weight + rated load). Counterweight rollers support part of the counterweight's weight and keep it moving stably along the counterweight guide rails, avoiding direct friction between the counterweight frame and the guide rails.
• Reducing Energy Consumption: By replacing sliding friction with rolling friction, they reduce the resistance during counterweight operation, lower the power consumption of the traction machine, and improve elevator operating efficiency.
• Buffering and Shock Absorption: The elastic material of the wheel body can absorb slight vibrations during counterweight operation, reducing noise and component wear.
