Substructure
Design Features:
1).Three kinds of substructures:box-on-box, two-step raising & sing-lift
2).The box-on-box structure: the front platform is suitable for installing standard BOP and the rear platform for installing heavy main drawworks and transmission groups
3).The two-step structure: the equipment on the drill floor and entire mast are raises together. The drill floor is equipped with two hydraulic cylinders, which serve the function of snubbing while raising the floor and push-back while lowering the floor.
4).The swing-lift structure: the substructure is raised integrally together with the mast . the mast ,the drill floor, and the equipment on the drill floor are all installed at ground level and raised with power of drawworks.
5).The substructures conform to API spec 4F and are used API monogram on them
