High Quality 350KN HDD Machine Horizontal Directional construction machinery horizontal core drilling machine

1. Main Structure Features A. Adopting advanced control technology for the hydraulic and electric systems, the rig is comfortable in operation; adopting wired remote control method; main components are adopted well-known brands home and abroad. B. Adopting well-known brand, the Cummins diesel engine has the features of lower emission and lower noise; combining international leading level control technique, the rig is not only more suitable to be performed in urban area, but has the power consumption reduced to the lowest level under the non-loading working condition of the rig. C. The rotation of drill head is driven with four low speed hydraulic motors, in large torque, set with 2 gear stepless speed adjustment. D. Drill head feeding/pull adopted four motors and reducer driving and adopting rack and pinion transmission structure, the rig is in high stability and efficiency.  E. Mud pump is driven hydraulically and in mechanical transmission, the pump can be adjusted flexibly for its pressure and displacement. F. Adopting steel crawlers with rubber track boots, the rig can not only sustain heavy loading, but travel on all kinds of roads. G. Provided with completed set drilling tools, including Φ73×3000mm drill rod, and the tools can be provided basing on special customization. H. Equipped with wireless guiding device, the rig is in easy operation. G. With robotic hand in option, it is easy for rod loading and unloading and in higher efficiency; thus the operators’ physical strength are largely decreased.
