Zdl series drilling rig is a top drive multifunctional drilling rig developed by our company according to the market demand for complex strata.

The power head belt has high-power top vibration, and the impact drilling effect can be achieved without DTH hammer and air compressor. The hole forming efficiency is high and the effect is good. Drilling tools are involved in the transmission of impact energy from outside to inside, so it is not easy to have in hole accidents such as sticking and burying, so as to reduce construction cost and risk.

High torque, high speed and high power impact energy make this machine suitable for most strata. So as to reduce construction costs and risks.

High torque, high speed and high power impact energy make this machine suitable for most strata. Especially for sand gravel layer, gravel layer, rock soil, sand layer and other strata that are easy to collapse and impact drilling, it has fast footage speed and hole forming efficiency. Especially when the water content of the local layer is too high to work with DTH impactor, the construction technology used by this machine becomes the best choice.

The machine is mainly used in: foundation pit support, slope support, various pilot holes, tunnel pipe shed and other projects.
