HFL40 Long Screw piling machine,auger drilling rig
HFL40 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.
