Product feature and appliance: Our Crawler type GPS machine is a type of piling machine which used the rotating drill rod and augers to bore the pile hole, the slurry or mud circulation is required during the drilling. In fact, this machine is the GPS engineering drilling rig mounted onto the crawler chassis, i.e. upgraded GPS boring machine.
The machine has electric powered self-propulsion chassis, it can move more freely from one pile to another at site, it can avoid using the crane to save client’s cost.
Important: This machine is electric powered, slurry or mud circulation is must.
Suitable for the geo condition: Rock hardness from the heavy weathered up to medium weathered rock, clay and sand. It is preferred that the underground water level is high.
Advantages: highly reliable structure and design, maintenance free, easy to operate.
Product feature and appliance: Our GPS boring machine is a type of light piling machine which use electric motor power to drive the turntable, the turntable will rotate the drill rod and drilling tool to bore the pile hole, and the tool gravity will give the pressure force, slurry or mud circulation is required during the drilling.
This machine is used to build bridge foundation pile, high raised building foundation pile, elevated road foundation pile and etc.
Important: This machine has to work with the slurry or mud circulation;
Suitable for the geo condition: rock hardness should be heavily weathered rock or soil condition, the mud circulation must be required while drilling. The working efficiency in hard rock is very low.
Man powers: one operator (captain), two labor forces for moving material and supporting works.
Supporting equipment: power supply (grid or generator); Excavator required to move the tools and earth, crane is optional; desander is optional depend on whether you want to recycle the mud.
Advantages: Simple mechanism and reliable machine, small capital investment, easy operate and no much experience required, running cost and wearing cost is less. Noise and vibration is much less, the pile wall is very smooth.
Disadvantage: Rock drilling is slow, mud circulation required.
