The machine adopts single row rope for main winch to figure out the wear of steel rope. and extend the life-span.
With infrared camera for observing main winch , Manipulator can observe the state of steel rope at day and night in cab.
Optional configuration according to customers' requirement (Eg: support cylinder , automatic positioning of slewing , Crowd Winch tyro crowd winch CFA, hydraulic casing oscillator, DTH hammer ) Excellent expansibility.
Adopting the supercharged CUMMINS engine with European Ⅲ effluent standard. Meet environmental protection and energy conservation . Super power.
With the hydraulic pressure system adopted threshold power control and positive flow control, the system acquired high efficiency and higher energy conservation.
The patented parallelogram articulated structure actualizes a wider work range . The highly strengthened box-type steel structure design makes the mast of highly-rigidity and intensity , therefore the drill accuracy is heightened .
The machine has passed CE certification of TüV Rheinland group.
Standard centralized lubricating system, allowing easier maintenance.
