After over 10 years improvements, the advantages is as below: 1) 40 types of the pile driver from 80T-1200T to meet the need of the customers.side piling and corner piling is avaiable. 2) Two patents in chinathe 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 . 3) Structure design .adopt variable hydraulic systems with low loss and constant power in this series ,apply merging hydraulic systems in the main part so as to save 30% energy consumption; .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; 4) Corner piling technologydirectly move the center pile driving device to the corner piling position,add on some countweight ,so its pressure can be reach to 60%-70% of center piling driving force. This structure of corner piling device wont deform,and with the same style for the center piling,it needt extra clamp. 5) Suitable condition .clay,soft soil,sand layer,etc; .noise regulated urban area; .vibration area such as the old building,subway,overpass,et paramete / typeZYC420B-Brated piling pressure(KN)4200piling speed(m/min)fast8.7low1.7piling stroke(m)1.9pace(m)longitudinal3.6horizontal0.7angle range(°)11rise stroke (m)1.1square pile(mm)max550mincirle pile(mm)max600minside piling space(mm)1250cirle piling space(mm)2500lifting weight(t)12.0lifting pile's lengh(m)14.0power(KW)piling111lifting30main dimension(m)lenth of work13.0width of work7.20transprorting height3.05total weight(T)≥420
