……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:The Montreal rotary drilling mud powder special effect is good
My site is based in Northampton, and it feels good
Q:Rotary drilling rig piling
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:What is a rotary cast in place 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.
Q:Construction scheme of rotary pile driver
Overview of drilling hole of rotary drilling machineAccording to the geological conditions of this project, and design requirements, combined with the pile foundation design parameters and requirements of the owner, the engineering pile drilling technology using rotary drilling rig, concrete using commercial concrete and steel reinforcement cage hoisting welding forming, lashing, catheter perfusion underwater concrete.
Q:What is the minimum drilling diameter of the Sany SR150C rotary drilling rig?
The minimum drilling diameter of Sany SR150C rotary drilling rig is 800 mm.
Q:How many piles per day can the bored pile foundation be 400mm and the pile is 25 meters long?
The pile can be divided into two kinds of bored pile and dug pile according to the way of hole formation. The digging pile is dug by hand, and the bored pile is made of mechanical hole, according to the mechanical difference. Bored piles are made of underwater concrete, and bored piles can be divided into the following types.
Q:How high are auger rigs and impact drills?
Rotary drilling rig upright, 20 meters to 28 meters, the more high, about 3.5 meters high transport status.
Q:When the rotary drilling rig is working, how does the rotated soil enter into the slag bucket?
(1) rotary drilling rig is the soil dust into the drilling bucket by drill pipe and the drill bit rotation and gravity, the soil dust filled with drilling bucket, lifting drill unearthed, so by drilling bucket rotation, soil cut, lifting and unearthed, repeatedly into the hole. According to drilling technology, it is divided into casing drilling method and stable liquid wall drilling method without casing.(3) the rotary drilling rig is mainly composed of operating system, power system, running system and drilling system (guiding column, drill pipe, drilling barrel, long and short spiral rod). Its operating system is mainly controlled by computer and hydraulic transmission. The power system is provided by diesel engine to drill and walk power, and adopts caterpillar type walking system (usually modified by excavator walking system).(4) drilling system is composed of drill bit and drill rod. Drill bit is made up of spiral drill and slag bucket. The drill bit is varied, and different drill bits can be changed according to different geological conditions. The chip type pumping rod drive a rotating drill bit drilling pressure and transfer required torque. The drilling rig is equipped with vertical and horizontal leveling system to ensure the verticality of the bore and to show the depth of the drill tube at any time and to keep abreast of the drilling conditions. The drilling rig has wide application range and high efficiency, and different drill bits can be configured according to different stratum during construction:
Q:For different geological conditions, how to choose rotary drilling, rotary drilling, impact drilling?
Such a soil condition, it is not recommended to use rotary drilling rig. The upper soil can be drilled with a rotary drill, and an impact drill can be used after the formation of rock.
Q:What brand is the best for rotary drilling machine?
Although the drilling rig imported from abroad is better than domestic brands.
