Wheelchair users often face height differences when boarding buses, trains, navigating uneven sidewalks, or entering buildings. Existing solutions like electric lifts and manual ramps are costly, complex, and inefficient. Electric lifts require high installation and maintenance costs, relying on power supply, while manual ramps demand human assistance, causing delays and lowering efficiency.

This hydraulic aid device addresses these issues by using a foot-operated hydraulic piston system that amplifies force by four times, allowing smooth, stable elevation. Once at the desired height, a check valve locks the system without continuous effort. To descend, pressing the control valve ensures a safe, gradual release. This design reduces exertion by 75%, enhancing convenience and safety.

The modular design allows quick installation and compatibility with most wheelchairs. It can be fully retracted when not in use, ensuring normal wheelchair operation. Suitable for public transport, hospitals, rehabilitation centers, and daily use, it improves efficiency and accessibility while reducing dependency on others. Durability tests confirm its reliability even after 10,000 full-load operations, making it a practical, sustainable, and efficient solution.
