CHARACTERISTIC
Main component configuration
DL800A horizontal directional drilling machine is a horizontal
directional drilling device for one machine. complete machine.The
main chassis, power head, drill rack, power station, vice, cab, car
crane, hydraulic system, electrical system and other components.
The chassis mainly consists of main frame and left and right
walking device. The rear end of the frame is provided with a
hydraulic support leg,
The walking reducer adopts Dagang Ning IKY34A7500 hydraulic
transmission device or the first oil pressure product,
1, chassis
The output torque is large and the structure is compact. Using wire
walking, transition loading and machine adjustment, convenient
safety
2, Power station unit
