Detailed Description

Specifications Drilling rigs for piling: 1. world-advanced 2. environmental-friendly 3. working ability 4. rotation of 360 degree 1.Uses The YF-HF-30 drilling rig is broadly used in the railway, highway, bridge constructions of industry and is very environmental-friendly mechanical product which is used in the urban construction. 2.Feature YF-HF-30 is very popular used in any kind of groundwork constructions. It’s a high quality design device. The long screw is developed for deep drilling. The pile holder adopts caterpillar type with flexible displacement and convenient emplacement.It applies electro hydraulic concentrative control which is convenient for operation. It has three-point support upright post that can be adjusted at the back and forth or on the left and right. The whole machine can realize the 360°revolution. The part of drilling tools apply three ring decelerator for power, key type flange as drill rod being safe, reliable and shortcut dismantling. The drilling machine can be equipped with construction techniques such as superfluid, high pressure slurry filling and dry method bore forming. 3.Security In the drilling operation, it has a high working efficiency, strong ability to break, without shock or noise, and a high degree of mechanization. It has better performance than hammering and pile sinking methods for penetrating the sand and gravel layers, at the same time, it can avoid the adverse effect on the adejacent buildings due to the hammering and vibration pile sinkings press on foundation. 4.
