Major features:
The rig is designed integrated with mechanical, electric, hydraulic, pneumatic and digital control. It takes fully the advantages of digital control, AC VF electric transmission. So its mechanical structure has been simplified.
Slingshot substructure: the drill floor equipments and driller's cabin etc can be pinned in lower position and raised integrally.
Electric transmission uses a vector VF drive system; fully digitalized operation and control are realized, automatic and intelligent operation and control functions as well. The control data and drilling data can be acquired (signal) , displayed, stored, printed, controlled and managed remotely.
The VF technology used makes Max. DW output torque at zero rotation speed to ensure the suspending function of rig hoisting system, which completely replaces traditional driller's operation mode.
Integrated driller's cabin makes the driller fulfill the main operation of drill rig in the cabin.
In accordance with the characteristics of low temperature environment, full optimized design has been made for materials, lubrication and sealing, hydraulic and pneumatic control, electric transmission and control etc. So it meets the requirements of -45 ℃~ 40 ℃ operation environment. The load bearing components such as crown block, mast, substructure, ladders, handrails, drawworks and the parts related to human safety are all made of the anti- low temperature materials.
There are automatic temperature-control electric heating devices for oil tanks of DW, RT and mud pumps, and steam coiled tube heater can also be used.
Heat reservation shield, steam-heating system are available to heat the racking board and driller's cabin locally, and other heating measures can be used for improving the operation environment as well.
