After over 10 years improvements by Tianwei Engineering Machinery Manufacturing Co.Ltd ,the quality of the pile drivers should be one of the best pile drivers in china now. the advantages is as below: 1)we have 40types from 80T to 1200T for customers to choice.each type is with multi-function,such as we can combine the embracing piling mechanism with top-pressing mechanismon the same machinery to make it as a two fuction pile driver. 2) two patents in china: the first one is ZL01249443.7,inverting cylinder as a supporting leg so as to avoid the easy breakage of cylinder which was the case with traditional design. The second one is ZL02139875.5,using the 16 cylinder clamping mechanism with multi-touching points to protect the piles from damage with clamping force . 2) structure design . adopt variable hydraulic systems with low loss and constant power in this series ; . use big power and great flow,and the pile driving mechanism with multi-speed operation to ensure the high efficiency of the while machine; . card board connection between horizontal movement mechanism and main machine body make it easy dismantled and installed; . the new designthat the crane can pass through the cabtomake it more convenient to transport. 3) suitable condition .clay,soft soil,sand layer,etc; .noise regulated urban area; .vibration area such as the old building,subway,overpass,etc the parameters are as following: parameter / typeZYC600B-Brated piling pressure(KN)6000piling speed(m/min)fast4.2low1.02piling stroke(m)1.9pace(m)longitudinal3.6horizontal0.7angle range(°)11rise stroke (m)1.2square pile(mm)max550mincirle pile(mm)max600minside piling space(mm)1250cirle piling space(mm)2500lifting weight(t)16.0lifting pile's lengh(m)15.0power(KW)piling111lifting30main dimension(m)lenth of work13.5width of work8.08transprorting height3.15total weight(T)≥600
