HFL40履带式长螺旋钻机采用刚性机架，上不作业机构采用三支点结构，立

The HFL40 crawler-type long spiral drilling rig adopts a rigid frame, the upper non-operating mechanism adopts a three-fulcrum structure, and the bottom of the vertical column is connected by a cross shaft structure. <br>The built-in hydraulic system is adopted. Except for the four legs that adopt hydraulic transmission, the rest adopt mechanical transmission. <br>The slewing mechanism adopts two slewing reducers, the slewing speed is adjustable, and the pile frame slewing is stable. <br>The main hoist adopts frequency conversion to control the rope speed. <br>All electric and hydraulic control are centralized. The machine is equipped with variable-frequency high-power power head, which can be steplessly variable within a certain range. There are two types of reducers equipped with the power head, one is a three-ring reducer and the other is a planetary reducer. <br><br>The HFL40 crawler-type long auger uses crawler walking, which has the advantages of flexible movement, rapid positioning, safe operation, etc., and greatly reduces the auxiliary time for construction. The machine has good hole forming quality, high efficiency, easy operation, no noise, no pollution, and high degree of mechanization. <br>Therefore, it is widely used in the construction of pile foundations for industrial and civil buildings, especially for the mechanized construction of pile foundations for urban construction.

The HFL40 track-type long spiral drilling rig uses a rigid frame, the upper non-working mechanism uses a three-point structure, and the bottom of the column is connected with a cross-axis structure.<br>The use of tibetan hydraulic system, in addition to the four legs using hydraulic transmission, the rest are mechanical transmission.<br>The swing mechanism uses two swing gearboxes, the swing speed is adjustable, and the pile frame swings smoothly.<br>The main roll control rope speed is used.<br>Electrical and hydraulic all centralized control, the machine is equipped with variable frequency high-power power head, in a certain range can be non-grade variable speed, power head equipped with two kinds of decelerator, one for the three-ring decelerator, one for the planetary decelerator.<br><br>HFL40 track-type long-spiral drilling rig with track walking, with flexible movement, fast position, job safety and other advantages, greatly reducing the construction auxiliary time. The machine has good well-made quality, high efficiency, easy to operate, no noise, no pollution, high degree of mechanization.<br>Therefore, it is widely used in the construction of piles in industrial and civil buildings, and especially for the mechanized construction of the construction pile foundation for urban construction.
