Relationship between sedan chair ladder and ground angle

Ensure the stability of the car, ensure the stability of the car.

1. Ensure the stability of the car: A proper angle between the ladder and the ground can increase the overall stability of the car. If the angle is too small, the car will roll over easily because of the unstable center of gravity when going uphill and downhill. If the angle is too large, the contact area between the ladder and the ground is insufficient, and the stability is reduced.

2. Ensure the stability of the car: a reasonable car angle can also improve the safety of loading and unloading operations. When the angle is too large, it is difficult for the driver to control the speed when going uphill and downhill, which increases the risk of accidents, while when the angle is too small, it is difficult for the vehicle to go uphill and downhill smoothly, which has potential safety hazards.
