1.dual-top drive power head 2.high lift capacity and output torque 3.good disassembility

1. Application YGS-120 anchor engineering drilling rig is a full hydraulic operated dual-top drive power head drilling machine. It is widely used to drill large pretension anchor wire holes, large diameter anchor pile holes and grouting holes at the side slope of water power station, expressway or railway projects, as well as small size foundation pile holes etc.

2.Features1) Dual-top drive power head realizes various drilling methods, such as:a) When drilling a hole in thicker (30~50 m) fractured zone or congeries, rear power head connected with the inner drilling tool and DTH hammer, to realize percussion rotary drilling, in the meanwhile, the front power head rotates the follow-up casing for protecting the hole wall.b) When drilling a hole in incoherent overlying formation, quicksand layer or silt layer, the inner drilling tool use conventionally rotary tools or long auger drilling tools, in the meanwhile, the front power head rotates the follow-up casing for protecting hole wall.c) When drilling a hole in intact formation, only one power head is used for ordinary rotary drillingor percussion-rotary drilling.2) It features high lift capacity and output torque, strong solving accident ability and high drilling efficiency.3) It carries out mechanization of rod and casing breaking down, as it equipped with the clamp and breakout machine, so it can significantly reduce labor strength and increase work efficiency.4) Building block and combined structure design as well as twin hydraulic pumps system are adopted in the machine, so it features good disassembility , convenient mounting and dismounting, and especially suitable for working in the inconvenient traffic mountain areas...
