ZD338 Rock Drilling Rig for Tunneling
The ZD338 rock drilling rig for tunneling is an advanced heavy tunneling equipment for tunnel excavation. It comes with three heavy duty hydraulic drill arms. Two arms can rise to 2 meters high, and the third one can drill holes downward with connected drill rods. A hydraulic carriage is available, and the operational area is quite large. This excavation equipment has a high degree of mechanization. It can be used for the traffic tunnel with a cross section area of 20-100 square meters, as well as the metal mine excavation, underground cavity digging, and so on.
Feature
1. Three sets of high performance DZYG38B heavy duty hydraulic rock drill are adopted, bringing the rock drilling rig a lot of advantages including high drilling speed, low energy level, low noise, and high efficiency.
2. The automatic control system can effectively reduce the overbreak and underbreak phenomenon, and greatly enhance the drilling efficiency.
3. The heavy duty hydraulic drill arms and high strength aluminium alloy propeller come with automatic parallel lifting mechanism and drill arm overall lifting mechanisms, giving the ZD338 rock drilling rig several important features like accurate positioning performance, easy operation, large and complete operational area.
4. The self-walking chassis has big power, so the drill rig has great tractive ability and excellent road adaptability. The closed type walking hydraulic system can achieve stepless speed changing, hydraulic direction turning, great driving experience, and flexible operation.
