1.JDL-350 mechanical top drive water and gas drilling rig
JDL-350 drilling rig is a mechanical top-drive drilling equipment that integrates water drilling and gas drilling, which solves the difficulty of drilling air-drilling hammers in soil layers. The problem of low mud drilling construction efficiency, the dual-purpose water and gas drilling rig is suitable for various formations, and the core drilling efficiency and geological exploration are efficient and energy saving.

Equipped with hydraulic steel tracks for stronger off-road capability;
Equipped with four hydraulic square tube high outriggers,which is convenient For leveling on site and saves a lot of loading and unloading costs; The left and right of the rig are equipped with drill rod holders and foot pedals, which are more user-friendly in design;
Equipped with four hydraulic square tube high outriggers,which is convenient For leveling on site and saves a lot of loading and unloading costs; The left and right of the rig are equipped with drill rod holders and foot pedals, which are more user-friendly in design;
The front end of the drilling rig isequipped with an auxiliary rod unloading cylinder, which makes it easier to loosen the drill rod;
The hydraulic oil pump is directly connected to the power by a universal shaft, which makes the rig climbing and moving more powerful;
AMT manual automatic transmission with electronic transmission and electronically controlled shifter make shifting easier;
The rig uses dual oil pumps to supply oil, and the hydraulic system uses split flow and merge technology to increase and decrease the power head more quickly;
Equipped with a foldable auxiliary tower, which can lift two 3 m / drill drill rods at a time.
