Patent ID: 6880838

Claim:
A cart for transport of material over a three-dimensionally curved surface of a structure, comprising: a base frame connectable at a front frame member to an anchor point of the building and having transport wheels for movement of the cart over the surface; the transport wheels including a set of casters located on the base frame for three-dimensional multidirectional movement of the cart over the curved surface and a set of roller wheels for movement of the cart over vertically inclined portions of the three dimensionally curved surface; a material basket for receiving the material and being movable with respect to the base frame, the material basket having a lower frame and an upper frame; support members extending upwardly from the base frame to support the material basket above the base frame; and pivot mechanisms between the material basket and the support members to allow rotational movement of the material basket between and with respect to the support members such that the lower frame of the material basket is positionable below the front frame member of the base frame, thus allowing the basket to remain in a horizontal position as the base frame moves over the vertically inclined portions of the three dimensionally curved surface.
