KJ311(Computer Assisted Type)Top Hammer Tunnel Jumbo Drilling Rig
Features:
KJ311(Computer assisted Type) hydraulic tunneling drilling rig is suitably qualified for the drilling of hard rock mine whose section falls in the range of 12-35 square meters.
It can realize automatic positioning,automatic control of rock drilling process automatic centralized lubrication,automatic fire extinguishing,automatic shutdown alarm and other functions,and real-fime operation parameters can be displayed through the network to achieve remote control;
The operating parameters of the equipment can be downloaded and stored after the password verification,which provides the basis for optimizing the construction scheme and changing the equipment parameters;
The firm flexible boom is capable of optical coverage of the section,articulated chassis of four-wheel drive ensure the flexible,fast and safe driving in the narrow tunnel;
Enclosed air-conditioned cab and a series of automatic functions provide a comfortable and safe operating environment;
All the relevant parts are kept in good protection,meanwhile maintenance easily
