……More info
1. Adopts the complete OEM Caterpillar retractable-crawler dedicated chasis，Its telescopic scope between the two crawler ends extends from 3000mm(at transportation) to 4400mm(at work). Undercarriage with expandable and removable tracks by means of hydraulic cylinders, guarantee exception stabbility in any type of ground. It has considerable traction force which allows easy movement even in the most difficult job sites.
2.Takes international top CAT Diesel engine with electric injection, turbocharged and air inter-cooling system. It is high reliability, fuel economy and power reserves. Emissions meet standard EPAC-Ⅲ.
3.The winches are positioned in the lower part of the mast, in front of the cabin, so that the operator can constantly check the proper operation. Thanks to the fact that the cable moves parallely to the mast, flection is not created on the upper part of the mast and operating life of the cable is therefore much longer. Tail positioned winch is available for heavy-duty type.
4.New design parallelogram system, computer optimized design and simplified pin connection system featured with nice appearance, great driving force and good stability, especially shaped to fit crowd system, allowing working radius adjustment always maintaining the mast in vertical position. The parallelogram system is easily for convenient transform between transportation and working conditions.
5.Self-erecting mast, high level anti-shock technology and high-strenth material steel attribute to that max torque can be applied all over the mast length. Multipurpose design for cylinder crowed system. Sensor and control center realize real-time measurement of the inclination angle, auto adjustment of mast verticality and inching adjustment.
6.Crowd system by means of long stroke hydraulic cylinder or crowd winch separately, are option for your exact request.
7.Rotary head with variable displacement motors and one high spin off speed. And rotary is extremely reliable, it has been disgned in order to gurantee a very compact, efficient and powerful rotary. The transmission group of rotary is made up of a hydraulic motor and new power shift purposely studied and designed to obtain maximum perfomance. During the drilling phase, the rotary has the entire power of the diesel at its complete disposal. Adapter of rotary is essential to absorb the considerable shock connected to the high speed of the main winch.
8.Telescopic kelly bar with guide made by high quality specially for high boring strength and torque force. Available with friction or inter-locking type.
9. All the main hydraulic components(pumps, valve, motor, connector) are from well-known international brands such as Bosch-Rexroth, brevini, which ensure the stability, reliability, high-efficiency and energy-saving of the entire system
10.Electronic controlling system is an innovative system, developed by Osaint, which controls and monitors the operation of the machines. For ease of operation, the system is controlled by a touch screen located in the cab. The system function is to enable the machines to perform different functions more efficiently. A dedicated power module electronic control and CAN-Bus system ensures the main pumps and Disel engine to work at their most effective and productive stages.
- Q:What kind of geology is a rotary drill suitable for?
- Wet (or bucket) and rock (core drill hole), with a large installed power, large output torque, axial pressure, flexible rotary drilling rig, high construction efficiency and function characteristics. To adapt to the soil geological conditions in most parts of the rotary drilling rig, with a wide range of basic can meet the needs of bridge construction, the use of high-rise building foundation engineering. At present, has been widely applied to all kinds of construction of bored pile drilling rig.
- Q:What are the components of rotary drilling rig Jixietaiban? How to calculate?
- This contract according to the geology and site conditions have different changes, according to a 24 hour standard, a drill, a crane, a forklift, each driver two, a site manager, coolie four, perfusion six, a welder, purchasing a drill, water pump and other auxiliary vessel some general tools, according to the size of pile, geological conditions of pricing, how much money per meter.
- Q:On the cleaning of rotary drilling rig
- You don't give a penny to anyone. Who wants to tell you?. The concrete steps of clearing holes can be used in the construction method of Baidu rotary drilling rig.
- Q:The difference between the rotary drilling bored pile and long spiral bored concrete pile?
- The difference between the rotary drilling bored pile and long spiral bored concrete pile is the main construction machinery, the hole is not the same. Long spiral for small diameter bored pile, more than 800 of the use of rotary excavation.
- Q:Is there a need to calculate the construction and transport of the mud pit separately in the budget of the pile driving pile?
- Rotary drilling rig is the first barrel type rotary drill through the bottom valve with broken rock and soil, and directly in the drilling bucket, and then by the rig hoisting device and drill rod of the drilling bucket dumping hole is proposed, so the cycle, constantly borrow dump, until the drill to the design depth. For the good cohesive rock soil layer, dry or clear water drilling technology can be adopted, without mud wall protection. For loose and easy to collapse formations, or groundwater distribution, unstable wall, it is necessary to use static mud wall drilling technology, and put in protective wall slurry or stabilizing liquid into the hole.
- Q:How can the drilling rod of rotary drilling rig be telescopic?
- It extends in the first order, the next second, and then the third, the last, the fourth, and the fifth. During drilling, it is stretched by gravity and bit by bit with the drilling depth. Rotary drilling rig in the multi-functional areas to improve, and it is not necessary to complex conversion can be converted to another device, it is worth studying.
- Q:Rotary drilling rig piling generally dozens of meters deep, when the next reinforced concrete generally divided into several times? In other words, a few meters per hour of reinforced concrete?
- The hole depth can reach 90 meters maximum rotary drilling rig, played more than 10 meters to 30 meters for building foundation above, for the majority of the viaduct, high-speed railways are, according to the bearing capacity and the design requirements of the formation of uncertainty, all possible. Generally, the pile diameter of rotary excavation is 0.8m, 1M, 1.2m, 1.25,1.5,1.8,2 meters in the majority, 2 meters, 5 also have, or larger and smaller.
- Q:Rotary drilling rig is not a special equipment?
- It is not a special equipment, it belongs to a pile machine
- Q:The advantages and disadvantages of the rotary drilling rig and impact drilling machine used in the construction of bridge bored pile foundation
- Three see is a friction pile or pile support, support pile must use cyclotron drill, or go after drilling friction pile on the pile bottom sediment is not high, can be used to drill, but to ensure the aperture piles in Yangtze River bridge 3 meters are used for drilling rotary drill rig. Positive cycle rig. Reverse circulation drilling rig (pump suction or air lift). Full bore rig. Punching and drilling. Manual hole digging.... Have to look at geology, there are advantages and disadvantages, and pile diameter, the bottom water level, the amount of engineering, land or on the work rack, the length of the pile, and so on, ah!Rotary drill: wide range of application. That is, the mud wall, the hole is not easy. Drilling speed is slow in rock geology;
- Q:How many meters of construction hole pile can be used for a selection of tile drill from input to scrap, whether it is related to the diameter of hole pile
- Rotary excavation life with maintenance, operation, construction geology, pile diameter have a great relationship.Maintenance needless to say, a little common sense of all know.Operation is like adults with children, teach good, just do not learn well, it is waste.The quality of construction geology is also very critical. Just like the 60 year old man, called him one night and three young woman gas Wang ML, certainly fall apart!Pile diameter size and depth: for example, type 220 rotary excavation, the maximum theory is 2 meters 5, depth of 65 meters. But it's really hard to reach. The geology is good. 2 meters will be enough. If you really do 2 meters 5 of the pile, it is like a night can only do 3 times, I'm going to do 5 times, 7 times.
