ABSTRACT:
A drilling derrick assembly is described which provides for the elevation above ground level of the assembly's working floor which supports both the mast and the drawworks. Prior to erection, the elevatable equipment floor is carried on a supporting substructure, and a mast is pivotally connected to the elevatable floor in a reclining position. When the assembly is erected, the mast is pivotally raised and attached in place, and other rigging steps can be carried out. Through the use of an integrally mounted sling and winch assembly or, alternatively, through operation of the assembly's traveling block, the entire equipment floor is elevated to the desired level.
