Long auger drilling rig is a new product which is based ondomestic and international advanced technology. It is aconstruction foundation equipment, which is not only applied forpiling foundation in housing construction ,but also for thetraffic, energy engineering and soft base enhance, etc,. CurrentlyCFG is listed as national new method and national constructionstandard.
Main Features
It can finish the pile in one time, perfuse pile at site andalso finish the operation of placing the steel cage. Efficiency,high quality and low cost are the main advantages of thismachine.
Simple structure ensures flexible move, easy operation andconvenience maintenance.
It is applicable for clay soil, silt and fill, etc. It canpile in different complicated geological conditions such as softsoil, draft sand formation, sand and gravel layers, withgroundwater and so on. Besides, it can construct cast-in-placepile, hi-pressure grouting-pile, grouting ultra-fluidized pile, CFGcomposite pile, pedestal pile and other ways.
There is no vibration, noise and pollution duringconstruction. It’s an excellent equipment for infrastructureconstruction.
Structure Features
Power Head And Drill Tool
The power head is composed by double electronic motor,three-ring reducer and hoist frame. The axes of the reducer connectthe drill tool by flange. The reducer fixes in the hoist frame andhung in the pillar rail. The drilling and piling work of reducer incompleted the hoister’s drive.
Drilling frame
The pile frame is three-point support structure and the pillarconnects with the machine by cross axes. This structure ensuresflexible operation. The walk type chassis’s move is based on thecooperation between walk cylinder and hydraulic leg and the crawlertype chassis’s move is based on the electronic motor and reducer.The up structure has main hoister and auxiliary hoister. Thefunction of main hoister is to finish the drilling work by movingthe power head and drill tool. The auxiliary hoister is used toinstall pillar and remove the steel.
Hydraulic System
Hydraulic pump, electronic motor, oil box, outrigger cylinder,pipe and control valves compose the hydraulic system. This systemcontrols the operation of outrigger cylinder and walk cylinder.
Electric System
The electric system is composed by electromotor, control cabinand other electric components. This system controls the electromotor’s start and brake. JZL120 model adopt frequency conversioncontrol and realize soft starting and brake and also meets speeddemand of power head and hoister.
Operation System
Operation room adopts thin board structure, three windows whichensures wide view and safety. The hydraulic system is controlled byfour multiway valves ,and electronic control componets are insideelectronic operation table or box. All operations are veryconvenient.
