A multi-purpose portable work bench cart has four wheels and two stacked shelves. The upper shelf is a table, which folds back to allow tall objects to be placed on the lower shelf. The cart frame is made of tubular stock. Parallel larger diameter sides extend forward and upward to a handle. Large inverted front and rear U\s support a fold-away table hinged at one side. Front and rear V-shaped trusses and a rear axle support the lower shelf. V-shaped trusses connect the rear axle housing to the sides. Front wheels are pivoted on vertical members extended downward from the sides. A locking mechanism on the frame of the cart is lowered and engaged to act as a brake for the cart.
