……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:In the middle of the 220 rotary drilling rig, sometimes the drill pipe slipped down 5~6 meters at work, as if the rope was broken. What's the matter?
The first is when the card drill rod, then the clamping rod parts will appear suddenly from the above phenomenon. Generally, the drill rod is worn out, and the biggest damage to the rod is the power head and the steel wire rope.
Q:Hole drilling price of rotary drilling machine
The geological conditions of deep hole depth into the empty aperture method whether it contains steel cage contains reinforced cage contains concrete auxiliary equipment whether party a gas station how to calculate the construction of reasonable charge pile head break
Q:What is the minimum diameter of a bored pile?
According to the regulations of rotary drilling and grouting pile operation regulations, the minimum diameter of rotary bored pile is 670mm, the drill bit diameter is 600mm, and the actual drilling hole is 670mm.
Q:The rotary drilling drill bit rock weathering by what
According to the hardness of rock to select the drill bit, in general hardness, with stainless steel drill bit, especially hard case with diamond or graphite steel bit.
Q:What drills are used to drill the hard layer of the rotary drilling machine?
I want to know how thick and big the pebbles are in you. Strong, weak, weathered, with double door fishing sand drill (pick teeth) can
Q:What's the difference between the main oil pump imported from the rotary drilling rig and the home made main pump?
. Under normal circumstances the main hoist is responsible for the drill pipe and the drill bit weight can be, but when the drill will be mud suction and pore wall friction in the air, so the main hoist lifting force of the drill bit and is generally greater than the gravity, sometimes if there are some things above the pressure in the collapse of the drill rod can better reflect the main hoist lift characteristics.
Q:31 rotary drilling rig, 280 pairs of steel wire rope, how long?
The main varieties of steel wire rope with manganese phosphating coating of steel wire rope, galvanized steel wire, stainless steel wire rope and coated steel wire rope, atmospheric environment, manganese phosphating coating can improve the wear resistance and corrosion resistance on the surface of the wire, inhibit the occurrence of fretting fatigue, and large increase in the fatigue life of wire rope, for reference only
Q:How often does the rotary drilling rig do maintenance?
1) each movement shall pay the grease according to the lubrication sign, and the main part of Carter shall be carried out according to Carter's lubrication requirements. For example: turning on the car, slewing bearings and other relatively large parts of the rotation, it must be in the entire rotary surface plus enough butter, each rotation of a certain angle to fill once;2) lubricate the main and auxiliary steel wire rope and butter each share;3) apply grease to the three sides of the mast rail;
Q:Tire type rotary drilling rig, drilling depth of 15 meters, diameter 1.2. This machine is how much money.
Should be OK, that is, the formation of the state must pay attention to, or else good equipment is futile.The estimated domestic product is around 2 million
Q:Does the rotary drilling rig cycle with mud?
Montreal chemical is a new type of rotary drilling fluid mud wall construction, is the foundation of companies and research institutes to develop and promote the products. The product is instant and can be sprayed into the hole along the jet stream.
