Product Features:
CFG series hydraulic foot-step multi-functional drilling rig with three-point support pillar which is adjustable all around. Logical structure, advanced technology, reliable performance, good appearance, flexible usage and cost-effective. Adopting centralized electro-hydraulic control, stable working, reliable operation and convinent maintenance. Easily assemble and disassembale. The pillar can be rised and fell by itselft. The host machine can be assembled and disassembaled by the chasis, no need of the cooperation of large tonnage crane. Drilling system power adopting tri-ring reducer, small machine, low weight while large bearing capacity and long service life time. Drill rod adopting key flange connector, safe, reliable and quick disassembale. Suitable for technics of super-liquid, high-pressure casting and dry drilling. Drilling and piling with CFG series hydraulic foot-step drilling rig, high efficiency, good quality, no vibration, no noise, no polution and high mechanization.

Better performance than hammer and sinking pile method for sand and gravel layer. Meanwhile, it avoids the press to foundation which results in the negative influence on neighbour buildings. This machine is applicable for clay, gravel, sand and soil layer, and also for the high underground water level formation, etc. Therefore, it is widely used in the field of industry and residential buildings and it is a kind of environmental protective piling machinery and specially suitable for the urban construction.
