The three major technologies of the heavy-duty stair climber: 1. The symmetrical double-crank actuator of the heavy-duty stair climber can realize the movement of going up and down, and conforms to the kinematics and dynamics principle, realizes the scientific force and action posture, and has a simple structure, high efficiency and low cost. Etc. 2. The edge brake technology of aggravated stair climber. The edge brake technology with completely independent intellectual property rights uses the principle of automatic gravity sensing and friction to realize the stair climber automatically recognizes the edge of the stairs, and then automatically stops, ensuring stable operation and the accuracy of the downstairs action. It has the advantages of simple structure, long life, zero energy consumption and low cost. 3. Advanced motor drive technology for aggravated stair climber. Self-developed motor drive controller can well control the stability of the motor under high load conditions, and realize automatic protection under abnormal conditions such as overcurrent, overvoltage, undervoltage, signal fluctuation, high temperature, and vibration. It has the advantages of stable structure, long life and low cost.
