Key features and benefits
Multi-dimensional posture adjustment to meet individual comfort requirements
The electric linear actuators provide comprehensive electric actuator system solutions designed for various types of wheelchairs, offering patients a wider range of comfort options, including height adjustment, back and leg support adjustment, lifting functions, and standing assistance. Users can independently adjust the seat height, backrest recline angle, and leg rest elevation angle according to their individual needs, freely switching between various positions such as sitting, semi-reclined, fully reclined, and standing assistance. From adjusting the wheelchair's height to optimizing the leg rests or altering the backrest position, every feature contributes to improved ergonomics.
Standing assistance function — the transition from "sitting" to "standing"
Some high-end electric wheelchairs incorporate a standing assistance function, which uses the electric linear actuator system to smoothly raise the user from a seated to a standing position. This feature holds significant rehabilitative value for patients with lower limb impairments who require standing training—it helps promote blood circulation in the lower limbs, prevent muscle atrophy, and improve bone health. The actuator provides smooth, controlled lifting and lowering movements, enabling users to transition from a seated to a standing position safely.
Compact and lightweight, suited to the limited space within wheelchairs
Wheelchairs require the integration of multiple systems—including the actuator, battery, controller, and drive motor—within a limited chassis space. Our miniature electric actuators are known for their ultra-compact design and lightweight construction, enabling them to fit seamlessly into the limited space between the wheelchair chassis and the seat. This compact structure not only provides greater design flexibility but also preserves the wheelchair's overall appearance and ease of folding.
Smooth and quiet operation, enhancing the user's daily experience
Wheelchair users rely heavily on their wheelchairs for daily tasks and generally wish to lead normal lives rather than constantly relying on the assistance of caregivers. Electric actuators provide users with movement they cannot control themselves, enabling reliable applications that reduce the inconvenience faced by people with disabilities. Our electric actuators operate at extremely low noise levels; the raising and lowering of the seat, the reclining of the backrest, and the adjustment of the leg rests are all performed silently. Smooth and seamless movement allows users to feel more at ease and confident when using their wheelchairs in public spaces.
Precise position feedback, enabling intelligent control
Our actuators are equipped with built-in Hall effect sensors, which provide real-time feedback on the actuator's travel position and operational status via pulse signals. The customer's control system can use this data to precisely manage key parameters such as seat height, backrest angle, and leg rest position, enabling intelligent functions such as one-touch reset and position memory.
