Claim 23:
24. A self-elevating platform cart for transporting onto a raised platform, the system comprising:
a main body structure;
a payload platform for carrying a payload coupled to the main body;
a main lift coupled to the main body and configured to be actuated to retract and extend, where the main lift includes a plurality of main wheels;
a fixed support beam coupled to the main body and configured to support a weight of the system;
a first height support coupled to a first end of the fixed support beam, the first height support having a plurality of first wheels, wherein a combined vertical height of the fixed support beam, the main lift and the first height support is configured to be greater than an anticipated height of a top surface of the raised platform and a combined vertical length of the first wheels and the first height support is configured such that the main lift can retract the main wheels to at least the anticipated height of the top surface of the raised platform;
a second height support coupled to a second end of the fixed support beam and having a plurality of second wheels, where the second height support is configured to support the system at a height such that the main lift can retract the main wheels to at least the anticipated height of the top surface of the raised platform; and
a controller module having one or more processors and one or more memory devices in communication with the one or more processors, the controller being configured to actuate the main lift, and the memory devices having computer-readable instructions stored thereupon that, when executed by the processors, cause the processors to perform a method for self-elevating platform control comprising, when an initial surface is adjacent to a raised platform and a destination surface is a top surface of the raised platform:
when the first wheels of the first height support contact the destination surface, retracting the main lift; and
when the main wheels are positioned over the destination surface, extending the main lift.
