A foldable wagon frame has a front wheel frame hingedly connected with a rear wheel frame to form a horizontal support frame when the frame is expanded. A lower part of the front wheel frame has at least two front folding rods, and a lower part of the rear wheel frame has at least two rear folding rods. A front folding rod and corresponding rear folding rod are hinged by a middle horizontal hinge shaft. A cross-folding frame is arranged below the horizontal support frame. The cross-folding frame includes a front cross rod and a rear cross rod. The front cross rod is connected with a lower end of the front wheel frame. The rear cross rod is connected with the lower part of the rear wheel frame. The front cross rod and the rear cross rod are hinged with each other through a vertical hinge shaft.

A foldable cart has a stabilizing handle device, which includes a connecting seat. The connecting seat has a connecting groove and two connecting rods of the foldable frame of the foldable cart are pivotally connected to the connecting seat in the connecting groove. A pulling rod mechanism is pivotally connected with the connecting seat. The connecting seat has a fixing strut that extends between the connecting seat and the foldable frame. When the cart frame is folded, the two connecting rods rotate about their pivot connections with the connecting seat, so that the two connecting rods approach each other. The connecting seat is fixedly connected to the fixing strut and a pivot point on the front side of the foldable frame so that an angle between the two remains fixed, which prevents the pulling rod mechanism from toppling left and right.

A hand truck includes a cart base for carrying an article and two handle modules pivotally mounted thereto. When the hand truck is in a first state, the cart base is horizontally positioned and one handle module is pivoted to an upright position. When the hand truck is in a second state, the cart base is kept upright, one of the handle modules is pivoted to a spread position, and the other one of the handle modules is horizontally positioned and cooperates with the cart base to carry the article. When the hand truck is in a platform state, the cart base is horizontally positioned, and the handle modules are pivoted to a downward extending position so that the cart base is away from the ground.

An infant stroller apparatus includes a front leg frame, a rear leg frame and a handle frame. The front leg frame has a first side portion fixedly connected with a first stop abutment. The rear leg frame has a second side portion having a protrusion. The handle frame has a side segment fixedly connected with a second stop abutment, the first and second side portions and the side segment being pivotally connected with one another about a common first pivot axis. The protrusion is restrictedly positioned between the first and second stop abutments when the infant stroller apparatus is in a deployed state.

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.
