Hydraulic drilling machines and DTH hammers are both used for rock drilling. The main difference between them is the drilling method.
As the name suggests, the down-the-hole drilling rig has a relatively shallow drilling depth, no hydraulic lifting device, and the hoist is used for lifting and lowering the drilling tools. Generally, a pneumatic impactor is used to wash the rock powder with air as the medium. The power system is generally a motor. The essence of down the hole (DTH) drilling machine is to make the impactor dive into the hole during the rock drilling process to reduce the energy loss caused by the impact energy transmitted by the drill rod, thereby reducing the impact of the hole depth on the drilling efficiency. In this way, a faster rock drilling speed can be obtained.
The full hydraulic drilling rig is a drilling rig that uses oil pressure to drive and control all moving parts. It is mainly composed of a main engine, a pump station, and a console. Hydraulic drilling rig machines can realize stepless speed change by means of high-pressure variable oil pump and variable oil motor. The hydraulic drilling rig can adapt to a wide range of drilling depths. It has a hydraulic lifting device and a winch for lifting and lowering drilling tools. Hydraulic impactor or pneumatic impactor. Flush the rock powder with liquid and air as the medium. The power system can adopt diesel engine or electric motor.

Hydraulic drilling rigs are used for drilling wells, such as oil or water wells, or holes for piling and other construction purposes, into the earth’s subsurface. Full hydraulic drilling rig is a drilling rig that uses oil pressure to drive and control all moving parts. According to its structure, it can be divided into vertical shaft type full hydraulic drilling rig and power head type full hydraulic drilling rig. Contact us to get a free quote now.
DTH drilling rigs are used in the mining industry, such as blast hole drilling, and drilling rocks, they can also be used for construction sites, drilling water wells, and in the oil and gas industry.

How do I choose between a hydraulic drilling machine and a DTH hammer for my project?
The choice between hydraulic drilling machines and DTH drilling hammers depends on the specific requirements of your project.
Hydraulic drilling machines are suitable for drilling deeper holes and are more versatile than DTH hammers. They are also more efficient in drilling through hard rock.
DTH hammers are ideal for shallow holes and are faster than hydraulic drill rig machines. They are also more effective in drilling through soft rock.
The choice between the two depends on the depth of the hole, the type of rock being drilled, and the speed required for the project.
