Bicycle Handlebar Turn Lever Tester

A liquid crystal touch screen and PLC control torsion program operation with a Chinese-language interface for easy use. Servo motor drive provides precise positioning, stable torque output, and low noise, supported by high-precision torque sensors for accurate torque measurement, while a dedicated adjustable fixture enables quick sample clamping. Using preset torque as the primary parameter and angle as an auxiliary parameter, the system reverses rotation only when both the set torque value and

The system uses a liquid crystal touch screen and a PLC to control the torsion program. The user interface is available in Chinese to support intuitive operation. A servo motor drive ensures precise positioning, stable torque output, and low noise. High-precision torque sensors provide accurate torque measurement. A dedicated adjustable fixture enables fast sample clamping during testing. The system uses preset torque as the primary control parameter and angle as an auxiliary parameter. Reverse rotation is triggered when the set torque value is reached and the specified angle limit condition is met; reverse rotation initiates only when both conditions are satisfied. Dual-layer safety mechanisms are incorporated.
