Design principle of hydraulic drive for vertical barrier free lifting platform, matched with 220V household voltage, safe carrying capacity of 300kg, smooth operation, and easy operation. To enhance the safety of platform operation, an automatic rocker is designed. When the equipment is raised during operation, the rocker will automatically lift up to prevent the wheelchair from slipping out of the platform. When the equipment falls back to the ground, the rocker will automatically unfold to form a cushion plate, making it convenient for the wheelchair to get up and down. For the convenience of passengers to control the platform, buttons and emergency stops are designed inside the elevator car for both the upper and lower equipment. Pressing the emergency button switch can control the machine to run up or down. When installing an accessible lifting platform, movable guardrails are usually installed at the entrance and exit of the second floor (upper) to increase safety protection. The installation of guardrails at the entrance and exit of the first floor will hinder the operation of passengers. Therefore, the technical department has repeatedly designed and experimented to add a safety descent protection bottom plate. During the platform's descent operation, the safety touch plate below will immediately stop running when encountering obstacles, greatly preventing accidents and enhancing the overall safety of equipment operation.
