    摘要： A versatile, low cost scaffold is constructed of commonly available materials and is adapted to be placed upon the bed of a tilt bed truck. When thereupon placed, the platform of the scaffold remains level as it is raised by tilting the bed of the truck. The scaffold comprises a lower portion which rests upon and is securely fastened to the bed of the truck. An upper portion, which includes the platform and safety rails of the scaffold is connected to the lower portion on one side by means of a hinge.
