Product Description:
Our raise borer KDTJ-3000L is developed and designed by our company based on the new characteristics of underground mining technology in China, and taking into account the advantages of the existing rail wheel drilling rig technology. This model optimizes the original rock drilling parameters and uses system integration technology to design a low profile for the entire machine size. The walking part adopts a crawler trailer to move, converting the longer solid body into a central articulated steering. Combined with remote control operation, it has a small turning radius, flexible walking, high safety, and better adapts to the development needs of domestic mines.
Features:
1) Adopting low-speed high torque motor and fully hydraulic drive technology;
2) Reasonable structure and easy operation;
3) Adopting a tire type chassis walking system, it has high traction and strong climbing ability;
4) High torque, stepless speed regulation for drilling;
5) Overall compact, easy and convenient to install;
6) High pore forming accuracy;
7) Strong ability and convenient transition;
8) Good impact resistance and reliable operation;
9) Capable of adapting to the operational requirements of higher rock hardness and large diameter shafts;
10) Adopting modular design for easy maintenance and replacement;
11) Advanced wireless remote control technology can be used to achieve safer and more convenient remote and multi-directional operation.

Applications:
Our raise borer KDTJ-3000L equipped with advanced drilling rod loading and unloading robots, the attached crane has been eliminated. It can directly pick up the drilling rod from the ground and send it to the unloading position without manual intervention, with higher safety and more stable and reliable movements. Only one person needs to operate the buttons to complete the entire operation process, greatly reducing the labor intensity of workers; Adopting a brand new hydraulic system, the application of hydraulic integration technology simplifies the hydraulic pipeline structure, and the load feedback type overflow free design reduces system heating and energy consumption, thereby improving the stability of the hydraulic system. The use of advanced hydraulic components and imported seals greatly avoids the occurrence of component leakage.
The walking part adopts a crawler walking trailer, which converts the longer solid body into a central articulated steering mode. The overall driving capacity and external dimensions of this vehicle are very close to the tunnel requirements of a 2m3 underground loader. The walking soft characteristic control adopts load sensitive proportional control technology to better achieve stepless speed regulation during the process and reduce the inertial impact of starting and stopping. High precision control of micro displacement ensures safer and more comfortable operation. The mature functional configuration that has been used for many years greatly reduces the occurrence of failures.
