HQZ-400L Drilling rig is a light, efficient and multifunctional drilling equipment. It is mainly suitable for drilling water wells, agricultural irrigation wells, geothermal air conditioning holes and other wells, especially for water intake projects in mountainous and rocky formations. The efficiency is more than ten times higher than that of traditional rotary drilling rigs, and the economic benefits created for users are extremely considerable. In particular, it solves the construction problems of rotary drilling rigs in hard rock layers, gravel, and pebble layers, and can work efficiently under various geological structures.

Main feature
-Crawler walking is more suitable for muddy field movement.
-Pneumatic drilling rig, with air compressor, the efficiency is equivalent to 10~15 times of ordinary drilling rig.
-The drilling on the rock is mainly based on the down-the-hole hammer drilling process. The down-the-hole hammer rock drilling operation efficiency is high, and the drilling cost per meter is lower.
