Frequently Asked Questions

What are the technical specifications of the GS500GAT/AT-LS?

The GS500GAT/AT-LS delivers 6,700KN pullback force with 160,000Nm rotational torque. Dual 353kW Cummins engines provide 946HP combined output. Maximum crossing length is 2000m with 2000mm reaming capacity. Drill rod diameter range: 140-219mm. Machine weight: 69.5 tons.

What is the rock drilling system capability?

The proprietary mechanical rock drilling system penetrates consolidated bedrock with minimal drilling fluid requirements. Designed for formations where conventional mud-based HDD methods are inefficient or impractical.

What are the hydraulic system specifications?

German-imported closed hydraulic system operating at 35MPa maximum pressure. 4-inch mud flow channels for effective cuttings transport. The system is engineered for extended operation in high-demand drilling conditions.

What geological conditions is the GS500GAT/AT-LS designed for?

Consolidated bedrock, fractured rock formations, unstable alluvium, mixed geology, and high-permeability formations. The machine handles formations requiring high pullback forces and advanced mud circulation systems.

What is the onboard lifting capacity?

Integrated 5-ton crane handles drill string assembly, pipe sections, and tooling changes without auxiliary equipment. Eliminates separate crane mobilization for standard operations.
