Product Introduction
The PQZ350L mechanical top-drive drilling rig is a self-developed drilling equipment by the company, capable of 90" drilling and integrating the functions of water drilling and air drilling (National Invention Patent: ZL201510479602.4). It is equipped with a 5-speed manual automotive gearbox, featuring a broad speed range, sensitive and easy forward-reverse switching, and high transmission efficiency—significantly lowering power consumption for enhanced efficiency and energy savings. It effectively addresses the challenge of difficult air down-the-hole hammer drilling in soil layers, as well as the low construction efficiency of rotary drilling rigs in hard rock formations, gravel layers, and pebble layers.
