Features
Parameters

◆ The first rotary drilling rig produced by Cat345GC chassis in the world.

◆ Energy saving, intelligent, HT entering - rock shows charm.

◆ High efficiency electric control hydraulic system, automatically adjust the hydraulic power of each engine speed to match the required working conditions, high efficiency and low loss of the hydraulic system.

◆ Power head multi-step control, can meet the requirements of various working conditions, high construction efficiency, low fuel consumption.

◆ The combined action of power head and main winch can effectively prevent absorption and improve working efficiency.

◆ By matching the opening and closing characteristic curves of the main winch reversing valve, main winch balance valve and main winch brake valve, the design of the main winch anti-slide rod prevents the failure of the main winch device, reduces the probability of the main winch anti-slide rod, and greatly improves the reliability of the main winch drive system.

◆ Single layer rope main winch, with large lifting force and long life of wire rope.
