A cart for transport of material, such as tools, equipment, supplies and the like on curved surface roofs of a building or other structure which as a varying or changing slope. The cart has a base frame mounted on rear wheels and forward casters. The base frame attaches by a rope or cable to an anchor point on the roof. An equipment basket is suspended at pivot points between supports extending above the base frame. The basket and its contents thus remain in a level, stable position on the roof as the cart is moved to various locations over the curved roof surface during use.

The cart of claim 2, further including a support bar extending between the base frame and the upright.4. The cart of claim 1, wherein the base frame has an upper end for connection to a support line mounted with the building and a lower end opposite the upper end and wherein the support members are located on the base frame closer to the lower end than the upper end.5. The cart of claim 1, wherein the base member has an upper end for connection to a support line mounted with the building and a lower end opposite the upper end and wherein the casters of the transport wheels are located below the upper end of the base frame.6. The cart of claim 1, wherein the base member has an upper end for connection to a support line mounted with the building and a lower end opposite the upper end and wherein the casters of the transport wheels comprise casters located below the upper end of the base frame for allowing movement of the cart over the three-dimensionally curved surface of the building.7. The cart of claim 1, wherein the base member has an upper end for connection to a support line mounted with the building and a lower end opposite the upper end and wherein the roller wheels of the transport wheels comprise wheels mounted with the base frame rotatable in a vertical plane to move the cart upwardly and downwardly over the vertically inclined portions of the three-dimensionally curved surface of the building.8. The cart of claim 1, further including attachment members on the cart for connecting items of material to the cart.9. A cart for providing work materials to service personnel on a three-dimensionally curved surface of a building, comprising:a base frame connectable at a front flame 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. 10. The cart of claim 9, wherein the base member has an upper end for connection to a support line mounted with the building and a lower end opposite the upper end and wherein the support members are located on the base frame closer to the lower end than the upper end.11.
