ABSTRACT:
The Invention is a cart for moving slabs of stone, such as marble and granite. In a first embodiment, main wheel support the weight of the slabs while front and rear end wheel prevent tipping of the cart. A hydraulic system withdraws the wheels, rendering the cart stationary. In a second embodiment, a main wheel carriage is clamped directly to a slab and bears its weight while smaller front and rear end wheel carriages clamped to the slab prevent tipping of the slab. The wheel arrangement of both embodiments allows the heavy slabs of stone to be readily maneuvered and rotated.
