Key Features & Performance Advantages

Smart System Upgrade

The latest system optimizes drilling operations, making use smarter and easier. This upgrade reduces maintenance costs by 20% through extended cycles, lower hydraulic oil use, elimination of pilot filters, magnetic shell filters, dust-resistant air filters, unified fuel/oil filters, and overall component versatility.

CAT Electronic Chassis

The TR158H rotary drilling rig adopts a new CAT electronic control chassis combined with a reinforced upper frame, significantly enhancing the overall operational stability and reliability.

Electronic Control System

The entire machine integrates full electronic control system monitoring. This improves component sensitivity, reduces response time, and substantially boosts overall work efficiency.

Optimized Hydraulic System

Eliminating the traditional pilot pump and fan pump in favor of a specialized electronic fan pump directly increases the net output power of the hydraulic system.

Advanced Power Head

The power head increases the guiding length of the drill pipe, protecting the assembly, prolonging the service life of the power head, and improving hole forming accuracy.

Flip-Chip Gear Box

Utilizing a state-of-the-art flip-chip gear box design on the power head dramatically facilitates maintenance accessibility and lowers long-term repair costs.
