DescriptionParameter

DFLS-20 bore pile drilling machine is new pile foundation construction machinery, adopting hydraulic  
walking
 type, electronic hoist, long spiral drilling. Hydraulic drive chassis canachieve 360° 
rotationposition,
movement, leveling etc. Action are quick 
and accurate. 

Self-propelled  folded pile frameuses two electric winchescan do drilling operation, also Lifting reinforcing 
cage on its own, perfusion operations. 

Power output shaft is hollow head, in addition to general long spiral dry method construction, 

but also for the construction of deep mixing method.
