The CFG series drilling machine is a kind of equipment for foundation construction as well as foundation treatment.It fits various kinds of foundation construction,like the CFG construction method,perfusion method and soft foundation strengthen etc. It's one of latest techniques and treatment for compound foundation construction,it has been listed as a new state-level construction technique and construction standard.

Our company's CFG series drilling machine has the features as blow:

1.The drill machine used the long screw to dig the hole and can perfuse concrete into the hole's bottom through the center of drill rod.It can make pile only by one machine in one time,as well as suitable for dry method,,replacement of infuse and some other construction processes.

2.The rotary head device adopted speed reducer with large hole through the center and drove by double-motor,which guaranteed the high bearing capacity,compact structure,low noise and long service life.It's the most idealest power device in domestic pile drive field at this present.

3.Hydraulic static moving device is adopted for this pile-driving frame,so that it can raise and down the arm frame automatically,walk,rotary and accurate emplacement and reliably,as well as high efficency and low strength of labor.

4.Drill rig adopts the combined way of consignment and shipment,features good integrity,easy to transfer and low expense cost.

5.All the monitoring instructions which for electric,hydraulic,operation are centralized at the driver cab.It's convenient and easy to operate.

Hydraulic Sysrem

The hydraulic system,including a assembly of oil pump motor,oil tank,support,cylinder,moving cylinder,sprag cylinder,oil tube and valve,etc. all of those are installed on the chassis.The controller centralized in driver cab makes the machine more easy to operate.

Drill rod and drill bit

Drilling machine uses screw drill rod and flange couping.There is no valve at the bottom of the drill rod,so that it can stop silt leaking into the centre tube.Moreover,the tube can open automatically when concrete or slurry is injected in by force.

Power Head

The power head consists of two wind cold motors,a speed reducer,an elbow,a pulling yoke,and a sliding block.When working,the two motors revolve the high speed shaft of the speed reducer through their couplings to pass power to the low speed shaft,then the low speed shaft revolve the drill pipe though its flange.The low speed shaft,being a hollow shaft,connects the syphon through a sealing device.
