摘要： A material handling cart is provided, having a frame with wheels and engaging members for supporting a part carried by the cart. Each engaging member has an engaging surface including a material for protecting a corresponding surface of the part from damage. Upper supports are attached to the frame and extend upward to a distal end, and have a height equal to or greater than a height of the part when the part is carried by the cart. Each upper support has an upper stacking coupler at its distal end. Lower stacking couplers are attached to the bottom of the frame. The lower stacking couplers engage upper stacking couplers of a second identical cart, to stack the cart above the second cart. The upper stacking couplers engage lower stacking couplers of a third identical cart, to stack the third material handling cart above the cart.
