Convenient transition and low transportation cost
Tires pull the chassis, allowing the vehicle to be directly dragged onto the road. It can move freely on rural roads and hardened surfaces without the need for large trailers, saving time and money when changing construction sites for short distances.
Dual use of water and gas, capable of penetrating soft and hard geological layers
Mud rotary drilling for soil and sand; Paired with an air compressor, it can drill granite, pebble and hard rock through pneumatic down the hole, taking into account both soil and rock layers, making it more suitable for a wider range of geological conditions.
The whole machine is lightweight and occupies a small area
The body weight is moderate, and it can be placed in rural courtyards, open fields, and small construction sites without the need for large-scale construction sites.
Fully hydraulic control, easy to operate
The hydraulic support legs automatically level and stabilize the body, and the valve group is operated centrally. The lifting, drilling, and unloading of the tower are completed by one person, making it easy for beginners to get started quickly.
Easy maintenance and low failure rate
The diesel engine has sufficient power, standardized accessories, easy replacement of vulnerable parts, and low long-term construction and maintenance costs.
- Replace air filters every 200-300 working hours
- Replace oil and fuel filters every 500-600 working hours
- Inspect vulnerable components monthly using precision measuring tools
- Maintain air compressor by draining moisture and checking belt tension
- For long-term storage: Clean thoroughly, apply rust-proof oil, and store indoors
- After harsh environment use: Perform deep cleaning and corrosion protection
