Request a Quote
One of the most attractive features of the hydraulic drilling jumbo for tunneling is its double-boom design, making it suitable for a large drilling cross section area. The tunneling jumbo has two drive methods, single-power and dual power, giving it a wider range of efficiency and power options. Equipped with a hydraulic drilling system, the underground tunneling machinery is extremely reliable and durable, making it the preferred choice by many companies involved in the construction and drilling of mines, tunnels and more.
