HFZL40 crawler type long auger rig with rigid frame, the upper operating mechanism with three-point structure, the bottom of the column using cross-axis structure connection. The built-in hydraulic system, in addition to four legs using hydraulic transmission, the rest are used mechanical transmission, rotary mechanism with two rotary deceleration. Rotation speed adjustable, pile frame rotation smoothly. The main winch uses variable frequency to control the rope speed. Electrical control of the use of centralized control. This machine configuration high-power variable frequency power head, in a certain range can be stepless speed, the power head is equipped with two kinds of reducer, one for the three-ring reducer, one for the planetary reducer.

HFL40 track long auger drilling the largest drilling diameter of 1.05 meter, the deepest drilling 42 meters, is currently the largest and deepest long auger.
HFL40 crawler-type long auger rig with crawler walking, with mobile flexibility in place quickly, operating safety and other advantages, greatly reducing the construction assistance time, the drilling machine into the hole of good quality, high efficiency, easy to operate no noise pollution, high degree of mechanization, Therefore, widely used in industrial and civil construction of the pile foundation construction, especially for urban construction with the construction of the pile of mechanized construction.
