CFG系列长螺旋钻机靠电器液压整机操纵、步履式行走方式。工作时采用长螺旋钻机钻至设计标高后，提钻时通过混凝土输送泵压灌混凝土成桩（亦可后插钢筋笼）。即成孔、成桩一机一次同步完成。安装回转接头亦可进行潮流态及常螺旋钻孔灌注桩等各种基础施工工艺。广泛应用于成见、居民建筑、能源、市政、交通、水里的灌注桩、挤扩桩、软基处理及城市高层地基处理的施工。具有不受地下水位限制、高校、节能、环保，过载能力强及机械化自动程度高等特点。ProductsIntroducedCFGserieslongscrewrigsonelectricalhydrauliewholesetsofmanipulation,whileawalk,worktodesignalongspiral2,274drillingrigs,todrillthroughconcretetran***issionpumppressurefedintoconcretepiles(alsoreinforcedcageinsertedafter)ProducedasasynchronousKongchengpilestallationotationjointsmayalsobeasupuerlongscrewboredattitudeandvariousoundationc***tructiontechniques.Widelyusedforurbanc***truction,energy,municipal,transportation,waterc***ervancythepile,expandingpile,thesoftbasewiththec***tructionofafreewaterrestricti***,andefficiency,andenergyc***ervation,environmentalprotection,automaticGuozainenglistrongdegreeofmechanizationandhigherfeatures．型号项目CFG13CFG15CFG18CFG20CFG21CFG23CFG25CFG26CFG28CFG30CFG31成孔直径/mm300～600300～600300～800400～800400～800400～800400～800400～800400～800400～800400～800成桩深度/m1315182021232526283031动力头功率/kW22×222×237×245×245×245×255×255×255×255×255×2***大提拔力/kN180180240240240240400400400400400主机转速r/min2121212121212121161612输出扭矩/kN.m15.815.83439393948.548.563.763.783行走步距/mm12001200120012001200120015001500150018001800回转角度°&plu***n;90&plu***n;90&plu***n;90&plu***n;90&plu***n;90&plu***n;90&plu***n;90&plu***n;90&plu***n;90&plu***n;90&plu***n;90桩机质量/T23243032.5333643455263.570)
