HD-40A5 Portable Drilling Rig
HD 40A5
The drilling rig is a full hydraulic driven and modular designed. Using quick coupling achieves rapid assembling and disassembling of hydraulic components and makes the drilling rig simple structure, fast connect and disconnect, convenient and reliable. The rotary, feeding/lifting of drilling tools are driven by hydraulic motor. The drilling rig is composed of 6 moving parts, such as power engine, operation platform, mast, power swivel, base and radiator. Maximum modular weight is 85
The drilling rig is suitable for seismic exploration, mine exploration, geological structure investigation and other drilling engineering construction operations in complex areas such as mountain, loess tableland, jungle, Gobi and seasonal farmland. The drilling depth is 40 meter
Technical characteristics of drilling rig:
- Adopting belt drive between hydraulic pump and engine which is flexible and safe.
- The engine is the original imported gasoline engine, equipped with heavy air filter.
- The hydraulic system adopts load induction variable system which is energy saving and high efficiency. The hydraulic balance valve is set in the system to ensure the smooth lifting of the drilling tools under the condition of load, which increases the reliability and safety of the system.
- Air power swivel is light weight and easy to be operated and moved. Also air and water power swivel can also be selected for the quick switch of air or mud drilling process.
- Stainless steel hydraulic tank improves the corrosion resistance of the hydraulic system.
- The drilling rig mast column adopts square pipe which facilitates moving. The feeding sprocket uses maintenance-free bearing support at both ends (patented products) to improve the bearing capacity
- The drilling rig structure is compact, can realize one person drilling operation.
