Convenient transfer transportation and lower cost
The whole machine is equipped with a tire driven chassis, which can be directly pulled onto the road by tractors and trucks. It can move freely on rural cement roads and hardened fields without the need for large flatbed trailers for short distance transportation, making moving fast and with low shipping costs.
Pneumatic down the hole efficient hard rock drilling
Equipped with an air compressor to achieve impact drilling, the drilling speed of difficult to drill formations such as granite, pebbles, and weathered rocks is much higher than that of a pure mud drilling rig, with a maximum drilling depth of 300 meters and high efficiency in deepwater well construction.
Dual use of water and gas, suitable for various geological formations
Mud rotary drilling is used for soil and sediment layers; Switching pneumatic down the hole dry drilling in rock layers, one set of equipment can handle various geological conditions such as soft soil, sand and gravel, and hard rock, with one machine for multiple purposes.
Hydraulic operation is stable and easy to operate
Four independent hydraulic support legs quickly level the machine body, without shaking during deep hole operations; Centralized hydraulic control panel, capable of lifting and lowering the drilling tower, adding and removing drill rods, and pushing and lifting by a single person, easy for beginners to operate.
Durable power and easy maintenance
Equipped with a high-power diesel engine, the winch has sufficient lifting force and is suitable for deep hole operations with long drill rods; Universal standardization of machine accessories, easy replacement of vulnerable parts, low long-term construction failure rate, and low maintenance costs.
The whole machine is lightweight and has strong adaptability to the site
The body weight is moderate, and it can be placed in flat open spaces, small courtyards, and fields without the need for large construction sites. It is suitable for scattered small-scale well drilling projects.
For long-term storage: Clean thoroughly, apply rust-proof oil, and store indoors
After harsh environment use: Perform deep cleaning and corrosion protection
