ABSTRACT:
The present invention is a combination carrier truck and umbilical drilling rig (10) which can reach into confined locations has sufficient power and can drill without any undue noise and fumes. Its preferred embodiment comprises a carrier truck (14), which carries a power plant, a control system and a self propelled drill rig (54) which is designed to drill in confined locations and is carried on the truck bed to a place desired for drilling. The drill rig has all the necessary mechanisms for locomotion over rough terrain and for actuating drill tools (86). The drill rig (54) is connected to the truck (14) by a hose (24) through which power and control signals are transmitted which may be bypassed for direct connection between the carrier truck (14) and the drilling rig (54). While being transported the drill rig (54) is secured to the bed (16) of the carrier truck (14). The rig (54) can drill holes while secured to the bed (16) of the truck (14). Alternatively the drill rig (54) can be moved off the bed (16) of the truck (14) via a detachable ramp (100) and moved to a location remote from the truck where drilling operations can be carried out.
