ABSTRACT:
A high accuracy medical trailer leveling system capable of detecting at least three level orientations including level along a longitudinal direction, level along a lateral direction at the front of the trailer, and level along a lateral direction at the rear of the trailer. The system also includes sensors that detect a level orientation in the longitudinal direction at the front of the trailer and a level orientation in the longitudinal direction at the rear of the trailer. A touch pad has buttons for controlling the system and a display screen, the display screen being capable of displaying a level condition in a particular location of the trailer and direction. The display screen can display the level orientation of side to side, front; side to side, rear; and front to back, and can also display the angle of inclination. One set of lights on the control pad indicates which jacks to actuate to level the vehicle, and another set of lights indicates which jacks are being actuated.
