It features superior overload resistance and ultra-heavy lifting performance, fully adapting to extreme working conditions of 7000m ultra-deep drilling and 9000m super-deep well heavy-load overhaul.

Super-Rigid Reinforced Modular Skid Base

Optimized ultra-heavy integral skid base and segmented modular splicing structure, with overall structural rigidity, compression resistance, torsional resistance and anti-vibration performance comprehensively upgraded. The uniform multi-point stress distribution design eliminates structural deformation, shaking and displacement during ultra-long-cycle heavy-load operation, providing extreme structural stability for super-deep well high-intensity construction.

High-Altitude Heavy-Duty Mast & Large-Diameter Rotary Table

Equipped with 44.5m high-strength lattice mast and 952.5mm (37-1/2") large-diameter rotary table, matching φ38mm high-strength steel wire rope. It supports large-size casing running and high-torque rotary drilling, perfectly meeting the construction demands of ultra-deep well large-diameter borehole operation and complex downhole stratigraphic exploitation.

Extreme Environment Ultra-Long-Duration Stability

Adopts industrial-grade enhanced circulating heat dissipation system, upgraded wear-resistant transmission structure and full coverage anti-corrosion, dust-proof and low-temperature resistant coating. It supports 24-hour uninterrupted full-load continuous operation in extreme scenarios including desert ultra-high temperature, Gobi drought and high-altitude severe cold (-40℃), with outstanding environmental adaptability and extended service life.

VFD Intelligent Full-Automatic Safety Control

Matched with premium fully enclosed intelligent control cabin, integrated VFD variable frequency drive system and MCC centralized control system. Equipped with full-process real-time parameter monitoring, dynamic load feedback and multi-level overload safety interlock protection devices, it realizes visualized, precise and automated ultra-deep well construction, greatly reducing manual errors and improving overall construction intelligence and safety standards.
