For those with good upper limb and trunk functions and normal hand eye coordination, they can not only use wheelchairs instead of walking, but also cross the threshold, go up and down the slope, and even use the following technologies to pass through the road teeth, wide steps, walking stairs and elevators.
Large wheel balancing technology
The so-called large wheel balancing technology is a technology that uses the inertia and power generation skills of the wheelchair to lift the small wheel in front of the wheelchair and maintain balance through only two large wheels. This technology is required in the process of passing through steps and kerbs.
The skills of large wheel balancing technology are as follows: sit in a wheelchair, keep your upper body straight, and hold your hands at the 10 o'clock to 11 o'clock position of the wheel rim (the position behind the middle); Pull the wheel rim backward with both hands and then push it forward quickly to lift the small wheel in front of the wheelchair off the ground; The small wheels are kept off the ground by controlling the wheel rim and trunk posture to realize the balance of the large wheels.
In the balance state of the large wheel, it is more convenient to pass through the steps.
