XR Series Rotary Drilling Rig stands for our company's achievement in many years' development and researches on piling machine, adopting the advanced technology, both at home and abroad. With our company's powerful machinery manufacturing capacity, it is specially designed to drill the pile hole with the big diameter and into hard-layers, fitting for layer conditions in most areas. XR280DII Rotary Drilling Rig widely used in boring operation of bored concrete pile in foundation engineering of highway, railways, bridges, ports, docks and high-rise buildings.
Performance Characteristics:
* The special hydraulic chassis for the rotating drill with extensible crawler is provided with the excellent stability and is convenient to transport. The imported Cummins turbo-supercharged engine (meeting EU-III standard) is powerful, and has sufficient power reserve, which can be operated in plateau. Its noise and emission meet the national standards. The constant power and the best output enable the complete machine to function at its best;
* The load-sensing technique is used in the hydraulic system to make it more efficiently and save more energy;
* The patented parallelogram articulation mechanism can work in a large area. The drill mast, which is designed in box structure and made of the materials with high strength, has good rigidity and anti-distortion, guaranteeing the drilling accuracy. The hinge is provided with the bearing exempt from lubrication, and can work freely. The slag can be discharged in any angle due to 3600 lifting and revolving;
* The intellectual controlling system, CAN bus and PLC with self-intellectual property right are used, including the automatic and manual regulation of the perpendicularity of the drill mast, automatic display of the drilling depth, automatic rotation positioning control, and intellectual fault diagnosis control;
* The machine adopts single row rope for main winch to figure out the wear of steel rope. extend the life-span. And high reliability;
* With infrared camera for observing main winch, Manipulator can observe the state of steel rope at day and night in cab;
* Standard centralized lubricating system, allowing easier maintenance; * The complete machine has passed CE certification of T ü V Rheinland group.
