Claim 18:
19. The system of claim 9, where the method for self-elevating platform control includes, when the system is positioned on the initial surface, the first step surface is lower than the initial surface, the second step surface is lower than the first step surface, and the third step surface is lower than the second step surface:
retracting the main lift until the first wheels of the first height support contact the initial surface;
extending the extensible support beams with the second height support;
extending the second height support until the second wheels contact the second step surface;
shifting the main body in the second direction on the extensible support beams until the first set of main wheels are above the first step surface and the second set of main wheels are above the second step surface;
a first retracting of the vertical stabilizer;
extending the main lift until the first set of main wheels contacts the first step surface;
adjusting the vertical stabilizer until the second set of main wheels contact the second step surface;
retracting the extensible support beams with the first height support until the first height support is adjacent to the main lift;
retracting the second height support to an inactive position;
retracting the main lift until the first wheels of the first height support contact the second step surface;
extending the extensible support beams with the second height support;
extending the second height support until the second wheels contact the third step surface;
shifting the main body in the second direction on the extensible support beams until the first set of main wheels are above the second step surface and the second set of main wheels are above the third step surface;
a second retracting of the vertical stabilizer;
extending the main lift until the first set of main wheels contacts the second step surface;
adjusting the vertical stabilizer until the second set of main wheels contact the third step surface;
extending the extensible support beams with the second height support;
shifting the main body in the second direction on the extensible support beams until the first and second sets of main wheels are above the third step surface;
a third retracting of the vertical stabilizer;
extending the main lift until the first and second sets of main wheels contact the third step surface; and
retracting the extensible support beams with the first height support until the first height support is adjacent to the main lift.
