Hand truck
Abstract:
A hand truck includes a carrying device connected to a wheel arrangement for transporting a load on a first support surface. The wheel arrangement is slidably displaceable with respect to the carrying device and can be selectively secured in a locked position when moving the hand truck on the first support surface. The carrying device including the load is transferable to a second elevated support surface when the wheel arrangement is slid toward a handle end of the carrying device. The wheel arrangement may be removed from the carrying device or alternatively pivoted for placement on the second support surface.
