Product Introduction
PQZ-500L Water and Gas Dual-use Series Drilling RigThe water well drilling equipment integrates the functions of water drill and gas drill. The drilling rig adopts a vehicle 525 gearbox, and the gear switching is sensitive and convenient. The transmission efficiency is twice that of hydraulic transmission, and the power consumption is reduced by 35%, making it more efficient and energy-saving. Solved the difficulties of drilling with air down the hole hammer in soil layers and the low construction efficiency of rotary drilling machines in hard rock layers, gravel, and pebble layers.
Dual purpose vertical and oblique drilling Rig
Mechanical transmission type power overhead drive is an efficient and multifunctional drilling equipment that integrates 0-90 ° multi angle mud drilling and pneumatic down the hole hammer drilling functions, especially suitable for drilling in complex formations such as backfill layers and gravel layers.

Packaging & Shipping
The PQZ-500L mechanical top drive driling rig is designed with transport convenience in mind. The foldable mast and compact crawler structure allow for easy loading onto standard flatbed trucks or containers, minimizing disassembly time and transport costs. The machine’s hydraulic leveling legs can be retracted to achieve a low center of gravity, ensuring stable and safe transport over long distances.
Whether shipped domestically or overseas, the XPH-5 modular design enables quick assembly and setup upon arrival, allowing operators to start drilling operations efficiently at the project site.
