Structure for setting up, positioning and orienting a mobile equipment carrier, comprising:
- a support structure on the carrier, establishing two vertically spaced support locations;
- at least three legs, having their upper end hinged to said support structure at an upper one of the two locations;
- and
- tension elements adjustable as to their length and being with one end each affixed to said support structure at a lower one of the locations, and further affixed with their respective other end to portions of the legs near respective lower ends thereof so that the lower ends of the legs can be individually pivoted towards the carrier by shortening individually the effective lengths of the tension elements, permitting lifting of the support structure to thereby lift the carrier off the ground.
