and won industry praise. Compared with other piling equipment, has the advantages of low investment,

high efficiency, quick recovery and so on, is an ideal choice for pile foundation construction users.

Main performance and features
1, High efficiency and energy saving, full hydraulic stepless speed change, reliable and stable transmission performance.
2, Large torque, large lifting force, especially suitable for complicated stratum such as gravel, hard rock etc.
3, The suspension tiltable power head and tiltable frame with compact and reasonable structure, easy to assembly and disassembly.
4, Large diameter drill pipe, using high-pressure gas lift seal device and advanced RCD method.
5, Optional additional weight to increase pressure in hole bottom, ensure the verticality of the hole.
6, Optional stabilizer to assist drilling, effectively control the verticality and hole diameter precision, reduce drilling tool wear.
7, Simple operation, low maintenance cost, comfortable environment of operation room, optional installation of temperature adjusting device.
8. High cost efficiency. the overall drilling costs can actually be reduced by up to 40% when using RCD, safety and requires fewer man hours, requires less water than other method.
9. Easy to collect samples. Any depth of the sample will help to study and analysis of geological condition.
