The handcart has various embodiments, each embodiment having a pair of larger wheels at the back of the load-carrying platform and a rear axle located above the plane of at least the forward portion of the platform. Smaller caster wheels are mounted on arms extending forward and outward from the forward corners of the platform. The outward ends of the arms are displaced upwardly to place the platform bottom only very slightly higher than the bottoms of the forward casters, thus increasing stability by lowering the center of gravity of the cart and contents, and facilitating loading and unloading of the cart due to the very low platform. The cart need not be tilted rearward to lift the platform from the floor, but may be pushed over the underlying surface with the load-carrying platform remaining level and with all four wheels rolling over the underlying surface.
