The core technologies of welfare lifters primarily include a rotational locking device and a lifting and transfer system. Key technical features are outlined below:
Rotational Locking Device
The patented "Rotational Locking Device for Welfare Seat Rotating Lift Base" (CN223085869U) developed by Shandong Mingao Automotive Technology Co., Ltd. utilizes a linkage plate and a lock plate to compress the linkage plate via a pressure shaft during the reciprocating motion of the rack. This lock plate engages the locking shaft when the rotating plate returns to its original position and unlocks during rotation, ensuring stable and safe movement.
Lifting and Transfer System
The new lift utilizes an electric standing assist mechanism. Combining a lifting arm, knee pads, and slings, it enables smooth transfers from bed or wheelchair to commode chairs. Lifting and lowering are controlled by a remote control, making transfers easy for caregivers and maintaining a comfortable sitting position.

Core Application Scenarios
Toileting Assistance: A sling and tilt function help individuals with limited mobility use the toilet independently, reducing the risk of falls. Bed/wheelchair transfer: Supports seamless transfer from bed to wheelchair, bathroom facilities, and other scenarios, reducing the burden of care
