摘要： A steerable carriage apparatus for manually transporting a payload across a surface, includes a frame having a frame first end portion and a frame second end portion, also included is a first rotating element rotationally attached to the frame first end portion and forming a first contact on the surface. Additionally, an arm having a pivotal attachment to the frame second end portion, the pivotal attachment having a pivotal axis that is at an obtuse angle in relation to the surface, the pivotal attachment is operational to allow pivotal movement of the arm in relation to the frame second end portion. A second rotating element in included that is rotationally attached to the arm and forming a second contact on the surface, wherein the obtuse angle is adjacent to the second contact, with the second rotating element being steerable.
