ZJL-160 Crawler-type Long Spiral Drilling Machine

Product Overview

The ZJL series crawler-type long spiral drilling machine consists of two parts: an electric crawler-type multifunctional pile frame and a drilling system. The pile frame adopts an electric crawler-type traveling mechanism, featuring a high degree of automation, capable of forward and reverse 180-degree rotation, rapid relocation, and flexible site transfer. The drilling system includes a power head and drilling tools. The output shaft of the power head and the spiral drilling tool are hollow. The pile driver uses long spiral drilling, and can pump concrete or mud through the central pipe of the drill rod for CFG pile construction, that is, drilling and pile formation are completed in one pass by one machine. When using this machine for bored cast-in-place pile operations, it has high hole-sinking efficiency and good pile-sinking quality. Its effect in penetrating gravel layers is far greater than that of the hammer-driven pile-sinking method. At the same time, it effectively avoids the adverse effects of soil compaction caused by hammering and vibratory pile sinking, which may endanger nearby buildings.  

Product Application

Widely used in foundation construction for mid- and high-rise buildings and bridges in urban construction, energy, transportation, and other fields.
