Claim 18:
19. An apparatus for moving an object across a ground surface, the apparatus comprising:
a platform having an upper surface for positioning the object on, the platform having a perimeter; and
a plurality of lift assemblies configured to selectively raise the platform off of the ground surface and permit the apparatus to move across the ground surface with the object carried on the platform, the plurality of lift assemblies being located along the perimeter of the platform, each of the lift assemblies having a deployed condition and a retracted condition, the deployed condition being characterized by the lift assembly facilitating movement of the platform across the ground surface;
at least one securing assembly for selectively securing the at least one lift assembly in the deployed condition;
wherein the at least one lift assembly includes a support arm movably mounted on the platform,
wherein the at least one securing assembly is configured to engage the support arm to selectively secure the support arm in a deployed position;
wherein the at least one securing assembly comprises a securing post for engaging a support arm of a said lift assembly when the support arm is in the deployed position; and
wherein the securing post is insertable into an aperture of the support arm when the support arm is in the deployed position.
