Product selling points

Single-layer rope main winch is adopted to effectively solve the problem of wire rope wear and increase the service life of the wire rope;

The infrared camera is installed, and the use of the main coil wire rope can be observed day and night in the cab;

A variety of configurations can be made according to user requirements (such as outrigger cylinders, automatic rotation, hoisting and pressurizing long spirals, pipe rubbing machines, pneumatic down-the-hole hammers), good expandability

Cummins electronically controlled turbocharged engine is selected to meet European Il emission standards with strong power;

Hydraulic system adopts power control and positive flow control to make the hydraulic system efficient;

The patented parallelogram luffing mechanism realizes a wide range of working areas. The drilling mast is designed as a box structure of high strength material, with high strength and rigidity, which can effectively guarantee drilling accuracy;

The whole machine has passed the European CE certification of Rheinland;

Centralized lubrication system as standard, convenient maintenance.
