ZEGA UP45 crawler down-the-hole mining drill is a new, efficient and specialized medium- and deep-hole drill which is independently developed by our company. It combines the capacities of overseas products and the technologies of domestic medium- and deep-hole drills. The purchase and maintenance costs are low, consumables are widely available, and equipment operation is easy.


Key hydraulic and electrical components are imported to ensure sound performance in harsh environments. The control system has gained recognition for sound performance in the markets.

Diesel and motor are used to provide power. The product is driven by diesel generator to move at a two-stage speed and by motor to operate with energy conservation and low noise.

Water spray is adopted for dust control. Water volume can be adjusted in accordance with particular conditions, and warning will be given in case of water shortage.

Application scopeStructure

It is primarily applied in underground mining, disasters relief, water conservancy projects, and anchor reinforcement.
