Safety gear and speed limiter: Under rated load, the safety gear can stop the platform and keep the platform in place within a distance of 150mm. When the safety gear is in action, the deflection of the platform shall not be greater than 5 degrees. When the safety gear operates, the power supply of the drive motor and the brake should be cut off at the same time. The speed limiter should accurately reflect the speed of the wheelchair platform, and the safety gear should be activated before the speed exceeds 0.3m/s.
