Crawler Tunnel Drill Rig PX-ZDY4600LPS

Product Overview

The PX-ZDY4600LPS is a crawler tunnel drill rig built for heavier borehole programs in underground coal mines and tunneling projects. Part of the PX-ZDY series of drilling and water injection equipment, it supports drilling, water injection and pressure relief duties. With an output torque range of 4600–1100 N·m and rotation speeds of 60–220 r/min, the rig can drive larger-diameter holes through harder strata while maintaining controllable penetration. Several torque and depth classes are available, and the machine is configured by project requirements to fit specific drilling plans and site conditions.

Product Description

The PX-ZDY4600LPS uses a reinforced crawler platform and a high-capacity rotary system to sustain demanding drilling conditions. Its nominal torque range of 4600–1100 N·m delivers the breakout and running torque needed for long holes and larger diameters, while rotation speeds of 60–220 r/min allow the operator to balance penetration rate against bit life. Structural features are project-specific and confirmed during configuration.

In addition to drilling, the 4600LPS performs water injection and pressure relief functions that support gas drainage and ground stress management programs in coal mines. An installed power of 55 kW and a machine weight of approximately 6,000 kg provide the stability and endurance required for repeated underground cycles. Because structural and auxiliary features vary by project, all final values are defined in the technical agreement and configuration sheet rather than assumed from the base model.

Technical Specifications

Applications

The PX-ZDY4600LPS is suited to gas drainage drilling, water injection and pressure relief in coal mines, as well as heavier borehole programs in tunneling and underground engineering. Its higher torque range enables work in harder formations and larger hole diameters where lighter rigs struggle. Combined with project-based configuration, the machine gives operators a durable, controllable platform for demanding drilling schedules and varied site conditions.
