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: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:What bucket teeth are used in rotary drilling machines?
We use the site above alloy bucket tooth, tooth special rotary drilling rig alloy, durable many times more than ordinary tooth Oh, but the price is several times more expensive than ordinary, but together, but it is still very good, after all, little change in time, save a lot of trouble.
Q:Rotarydiggingmachine life
Electronic equipment for 3 years. Note: construction machinery generally adopts the fast depreciation method, if your car does not recover the cost within 1-2 years, then you lose, and the later maintenance fee is definitely not a small number
Q:Do you need electricity for rotary drilling rig?
If you don't use electric drive, it depends on hydraulic oil
Q:Kim Taixuan drilling operations and other brands of rotary drilling operation do.
Each manufacturer of rotary drilling rig has its own advantages and disadvantages, the truth is basically interlinked, but need to find out the performance of the machine, but also need a specific practice, you can try,
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:There are several brands of rotarydiggingmachine
Hyundai: Korean brand, but it is low-end goods, assembled. (HYUNDAI)Advantages: cheaper prices, good parts to buy, cheap.Disadvantages: machines can't even reach the standard of domestic machines, either good or bad.Personal view: imported brands can only buy more than these brands, Keith (CASE), JCB (JCB), Kato (KATO), Terex (TEREX), Bohai Seoul (LIEBHER), Sumitomo (SUMITOMO), Ishikawa Shima (IHI), Kubota (KUBATO), Takeuchi (TAKEUCHI) are not allowed to buy. Low share, customer service service points less, difficult to buy accessories, if you buy, there will always be these problems.Komatsu and Carter belong to the independent production brand, the primary consideration
Q:Rotary drilling rig when piling, the drill bit off the hole in the pile, how to fish ah?
If more than fifteen meters, a thin rope tied down with the steel wire rope is fixed on the pull. If you don't deep human, not safe, do a salvage device on the line, is a piece of steel, cut into type L, L below the horizontal slightly upwards with a point of view, with the top of the vertical wire rope L, you can then put on the bit.
Q:Does the rotary drilling rig need mud?
It needs mud and wall protection, and there are certain standards.
Q:What are the equipments used for bored pile construction?
Rotary drilling can be divided into positive circulation, rotary drilling, reverse circulation and rotary drilling. Its characteristic is that the slurry circulation is different, the mud is pressed into positive circulation, and the pumping mud is reverse circulation.It is suitable for the circulation of clay, silt, fine sand, and other types of soil; reverse circulation for cohesive soil, sandy soil, sand and gravel and weathered rock, but the pebble size shall not exceed the diameter of the drill pipe 2/3, and the content is not greater than 20%.
