JVR285HT 85meters depth Rotary Drilling Rig with 285Kn.m
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
