Drilling depth range: 3000m--7000m
With mechanical chain transmission between power unit and driving unit, it combines the features of the electric-drive and mechanical-drive drilling rigs. Rotary table drive is controlled by AC VFD motor or DC motor, realizing stepless speed regulation. Main brake of drawworks is hydraulic disk brake, stand-by brake is electromagnetic eddy current brake. Drawworks can be gear shifted by air remote control without parking. Substructure design refers to the "high front platform & lower back platform" layout of mechanical drilling rig, which is convenient for transmission and power system installation. Front platform adopts "swing-up" structure. Data control adopts intelligent PLC system in driller console to perform logic control, remote supervision and protection, data store and print.
