ABSTRACT:
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.
