CFG 20/25/30 Pedrail Тип Длинные спиральные сверла Рог

The series CFG driller is a new kind of drillers.It is jointly developed by the Construction Machinery Comprehensive Reaearch Institute and our company with advanced new technologies.The CFG series and its construction process has been nominated to a new state-level-construction process. The series CFG consists of two parts,the pile-driving frame and the drilling system .Pile-driving frame adopts the series JZL trackes-type or the seriess JZB step-type walk,which makes movements flexible and repositionning rapid. ·The rotary head device adopts the national patent techniquetri-circle speed reducer which features high bearing capacity and reliability.Equipped with swivel joints, the output axis and the auger stem are hollow inside,which allows long spiral processing and supefluidity construction. ·During operation,no vibration,noise or pollution arises,which brings a high rate.The CFG series is the ideal equipment for civil and industrial construction.
