High-torque Crawler Tunnel Drill Rig PX-ZDY8000LPS

Product Overview

The PX-ZDY8000LPS is a high-torque crawler tunnel drill rig designed for deep and large-diameter borehole programs in underground mines and tunneling projects. Within the PX-ZDY series of drilling and water injection equipment, the machine supports drilling, water injection and pressure relief duties. An output torque range of 8000–2000 N·m provides the power base for demanding hole geometries, while rotation speeds of 50–200 r/min keep penetration controllable in hard ground. Multiple torque and depth classes are available, and the rig is configured according to project requirements.

Product Description

The PX-ZDY8000LPS combines a heavy crawler chassis with a reinforced rotary feed system to handle sustained high-torque output. The rated torque range of 8000–2000 N·m supports breakout and drilling in consolidated rock, and the rotation speed band of 50–200 r/min gives operators latitude to adjust parameters for different strata and tooling. Structural features are arranged in line with project-specific configurations.

As a multi-purpose boring unit, the 8000LPS covers drilling, water injection and pressure relief tasks central to gas drainage and stress management in coal mines, as well as larger tunneling boreholes. The rig uses an installed power of 90 kW and has a machine weight of approximately 6,500 kg, combining strong output with manageable transport within underground workings. Final specifications, including hydraulics and auxiliary equipment, remain subject to configuration and are confirmed through the technical agreement and configuration sheet.

Technical Specifications

Applications

The PX-ZDY8000LPS is intended for gas drainage, water injection and pressure relief drilling in coal mines, and for larger-diameter borehole work in tunneling and underground construction. Its high torque capacity suits consolidated and hard strata where deep, large holes demand substantial breakout power. Project-based configuration allows the rig to be matched to specific hole programs and site conditions, helping operators maintain drilling performance and reliability on demanding projects.
