box on box type 

block-combination type 

slingshot type 

swing up type 

telescoping type

The substructure of box on box type or block-combination type, has a relative higher clearance at front platform, satisfies the installation requirement of standard BOP, if the substructure at back platform is lower, it is required to use heavy equipments such as drawworks and transmission unit etc.

The substructure of slingshot type is used for electric rig, the drill floor and equipments on it can be installed at low position , and then the drill floor and mast can be raised together. There are hydraulic buffer cylinders on the left and right of the drill floor, while mast rising, they act as bumper, while laying down, they act as a push force.

The swing up structure, the drill floor and equipments on it can be installed at low position , and the mast can be raised at low location of drill floor, then the whole drill floor.

The telescoping structure, mast and substructure are lifted with hydraulic cylinder ; the structure strength is properly , small weight, easy for rig-up and transportation.

Conforming to API Spec 4F, marked with API.
