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.
