Product Description:

OTR140D:
①. Base: CAT 329D(HHP)
②. Max pile diameter (mm): 1800
③. Max pile depth (m): 60
④. Engine: CAT C7 ACERT 187KW
⑤. Maximum nominal torque (kNm): 200
⑥. Undercarriage with expandable (mm): 3000-4300


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: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:How about the speed of rotary drilling rig?
Not at all. It depends on how you do the work.
Q:What is a rotary pile?
In China, it is an advanced pile foundation construction technology, which is widely used in recent years. It is widely used in highway, railway, bridge and large building foundation pile construction. In the early days, most of the rotary drilling rigs were imported from Germany and Italy, or Japanese second-hand rotary drilling rigs. In recent years, with the Qinghai Tibet railway, Beijing bird's nest and other projects to promote the influx of foreign brands, China's similar products are gradually developed.
Q:How to distinguish the performance of rotary drilling rig?
The main hoist and power head are combined with multi main valves to minimize the resistance along the way and improve work efficiency. The main hoist and the power head adopt double circuit control in the compound action to ensure the independent control of the compound action, and improve the ability of the drilling rig to deal with complicated working conditions.
Q:Rotarydiggingmachine operating permit test how
Rotarydiggingmachine also called rotary drilling rig. The utility model is a tool for road traffic and high-rise building construction. The rotary drilling rig is a kind of comprehensive, it can use the short helix bit dry digging, can also be used in wet digging rotary drill mud case. Rotarydiggingmachine with hammer drill hole digging work pieces after hard formation. If the enlarged head drilling tool is used, the reaming operation can be carried out at the bottom of the hole. Rotary digging machine adopts multi-layer telescopic auxiliary drilling drill pipe, less time, low labor intensity, without mud circulation deslagging, cost saving, no pollution, infrastructure construction is especially suitable for the construction of the city.
Q:Attention problems of rotary drilling rig
The rotary support first run 100 hours refer to, should check the bolt preload, after check every 500 hours of operation time, must keep enough preload force. Attention shall be paid to the operation of the slewing bearing in use. If the noise, shock and power suddenly increase, the utility model shall be stopped for inspection immediately, troubleshooting, and dismantling if necessary.The use of water is not allowed to directly wash the slewing bearing to prevent water from entering the raceway. Prevent hard foreign objects from approaching or entering the meshing area of teeth. To regularly check the integrity of the situation, if found sealed damaged should be replaced in good time. If it is found to fall off, it should be reset in time.
Q:The difference between rotary drilling machine and rotary machine.
Different drilling principle: rotating drill through the rotary drive pipe, and connected by drill bit cutting rock, rock chip cutting down the drain hole through the mud circulation; and the rotary drilling rig is through the first power driven drilling bucket digging, drilling bucket filled with soil after the hole dumping, this repeated cycle into the hole.
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:How much oil is used in the 31 rotary drilling rig?
Check whether the fuel tank is adequate and the oil is normal;
Q:XCMG XR360 rotary drilling rig generally how much?
5 million 700 thousand standard 508 drill pipe, section five 77 or four Mimo resistance pipe, section 62 meters machine lock, two optional one
