Basic features: Equipped with a dual cylinder hydraulic feed system, fast drilling speed. There is a 4-speed transmission system, with 3 forward gears for freely adjusting the speed, and 1 slow reverse gear for easy disassembly of the drill rod. The drilling rig is equipped with a fixed clamping mechanism and an integrated main pole, without the need for a drilling tower. The operating handle is centralized and easy to use. In addition, it is equipped with a bottom pressure gauge that can indicate pressure, making it easy to grasp the situation inside the hole. The drilling rig has a compact structure and strong decomposition ability, making it easy to relocate in complex terrains such as hills and mountainous areas.
