摘要

An arrangement to support a drawworks and drilling mast in elevated position during drilling operations and which also functions to transport the drawworks and drilling mast includes a base support and an elevated support with jacks pivotally conncted to the base support and the elevatable support and extending herebetween. Wheels are mounted on the elevatable support for transporting the base support elevatable support, the drilling mast and drawworks carried on the elevatable support. Brace members are pivotally connected between the base support and elevatable support to retain the elevatable support in elevated position during drilling operations. A support including an A-frame retains the drilling mast in generally a horizontal position on the arrangement during transport and the drilling mast is pivotally connected to the A-frame intermediate the ends of the drilling mast whereby the foot of the drilling mast may be moved about the A-frame and secured at its lower end to the base support to retain the drilling mast in an erect position for conducting drilling operations.
