Center-mounted Tunnel Drill Rig PX-ZDY1200LPS

Product Overview

The PX-ZDY1200LPS is a center-mounted tunnel drill rig in the PX-ZDY series, developed for borehole construction in underground roadways and tunneling projects. The center-mounted layout positions the drilling unit along the machine axis, improving stability and simplifying alignment in confined headings. As part of the drilling and water injection equipment range, it supports drilling, water injection and pressure relief applications and is arranged in multiple torque and depth classes. Because final specifications depend on project requirements, all key parameters are confirmed through the technical agreement and configuration sheet.

Product Description

The design philosophy of the PX-ZDY1200LPS centers on stability and maneuverability. By mounting the drill unit along the vehicle center line, the machine distributes its weight evenly, reducing tipping risk and making positioning easier in narrow tunnels. The crawler-based chassis provides mobility across uneven underground floors, while the compact envelope allows the rig to enter sloping or restricted headings where larger equipment cannot operate.

The machine is intended as a multi-purpose boring platform, supporting drilling, water injection and pressure relief duties common to coal mine gas control and underground engineering. Several torque and depth classes are available so that the rig can be matched to different borehole programs. Because project conditions vary, performance values, auxiliary systems and installation options remain subject to configuration and are confirmed before delivery to ensure the unit fits the client's operating environment.

Applications

The PX-ZDY1200LPS is suitable for gas drainage drilling, water injection and pressure relief in coal mines, as well as borehole work in narrow tunnels and underground engineering sites. Its center-mounted arrangement supports straight-line drilling in confined headings where stability and precise alignment matter. Project-based configuration helps operators match the rig to specific hole programs and site utilities, improving efficiency and reducing mobilization effort underground.
