ABSTRACT:
The upper works of a boom machine such as a crane is supported for rotation about a vertical axis on a lower portion of modular construction. The lower portion comprises a hub-like member having four leg module holders which are equidistant from said axis and spaced around it at uniform intervals and to each of which a leg module is detachably securable. To outer ends of the leg modules can be secured pad modules or extension leg modules that have ground engaging pads at their outer ends; or laterally opposite pairs of leg modules can be detachably connected to crawler modules. The hub-like member also has a pair of body module holders at opposite sides thereof, each laterally intermediate a pair of leg module holders, to which wheeled transporter modules can be detachably secured. Alternatively, with crawler modules installed, a hydraulic power module for energizing them can be secured to one body module holder. When not supporting the machine for transport or as a truck crane, transporter modules can serve as auxiliary counterweight carriages.
