Simple maintrnance. Te fault ratio an maintenance cost of te electrmotor is far lower than the diesel engine andhydraulic driven system; Stable walk and safe wofk. Because the griunded dimension isn’t limited by thechassis of the crane and 4 hydraulic support-legs are equippesd , the heelover and turnover accideng dosen’t iccur.
The vertical degree of the piling is high . The standpole has three-point rupport and two-orientation; the drill vertiacal degree is better thanthe hanging-pedrail piling-
It is in favor of the city construction and environment oritect . The driven noise of the electromotor is smaa and the resident isn’t disturbed; the diesel oil isn’t burnt without the exhaust gas.
It alks neatly and quidkly with high efficiency .The move-difficulty in case of the support-legs sink does’t occur . The construction efficiency is increased over two times withour dead angle.
Because of the above advantages , JZL Series of dynamoelectric pedrail piling-
