All about Bauer drilling rigs

During large-scale construction, it is impossible to do without large equipment, which allows you to perform tasks of increased complexity in the shortest possible time and with proper quality. Drilling rigs used by large companies fit this criterion. On the market, these products are represented by Bauer, which has several models in its assortment.

The German company Bauer is known as a manufacturer of large-scale construction equipment, which is sold all over the world and is used on many projects. Of the features of the technique, the following can be noted.

• High level of mobility. Thanks to the chassis, the equipment can actively move around the construction site. At the same time, a small base area does not interfere with the work of other equipment located nearby, when it comes to large-scale construction.
• Performing a large amount of work. Bauer drilling rigs have considerable capacity, which, together with the available equipment, allows you to drill large wells in a fairly short time.
• Functionality. All the equipment available on the installation allows the production of depressions of various widths and shapes, which makes the result of the work process more preferable for the consumer.
• The possibility of modernization. If desired, this technique can be equipped with other parts and installations, which makes the original characteristics valid only until the first design changes.

Now it is worth making an overview of some of the models that have become the most famous from this manufacturer.

One of the first models for universal use. The main areas of application are the creation of bored piles with a diameter of up to 1900 mm, as well as drilling of wells with various types of nozzles, including auger and soil unroller. This model is used to create wells without and with casing. There is a possibility of immersing sheet pile pipes used for enclosing excavations. The maximum drilling depth reaches 71 meters, the total installation height is 26470 mm. The rotary drive KDK is available with a torque of 275 kNm at a pressure of 320 bar. The maximum rotational speed is 35 rpm, the pressure and thrust forces are respectively 200 and 330 kN.

The average speed is 7 m / min, in rapid traverse mode this parameter increases to 8.5. There is both a main and an additional winch. In the first case, the length is 90 meters at a speed of 80 m / min, in the second 60 meters and 74 m / min. Pulling force of the effective type is 100 kN, nominal 125 kN. As for the working cab, it is equipped with a CAT C11 engine, which has a rated power of 313 kW, a fuel tank of 800 liters, allows for long-term work. In the cab sound level 78 dB, hydraulic power 230 kW, undercarriage width 3700 mm in extended position. Travel speed 1.1 km / h, operating weight 96 tons.

Larger drilling rig that allows drilling holes up to 68.6 m deep. The main way of working is using a kelly bar, auger or a soil unroller. The total height is 24240 mm, the rotor power is 367 kNm, the maximum rotational speed is 46 rpm, and the traction force is 400 kN. 7250 mm kelly stroke, for CFA 16700.A distinctive feature is the high rapid traverse speed of 26 m / min, in standard mode only 6.5. The length of the main winch is 90 meters with a maximum speed of 90 m / min, for the additional winch these figures are 67 meters and 55 m / min, respectively.

The working cab is equipped with a 354 kW CAT C15 engine. An 800 liter fuel tank is provided to power the entire unit. The ambient temperature during maximum load can rise to 45 degrees Celsius, the sound pressure level is about 78 dB. The hydraulic power of 277 kW and the pressure of 320 bar allow efficient drilling. And the UW 110 self-propelled chassis with a convenient swivel mechanism - to move over the entire area of ​​the object. The maximum speed is 1.3 km / h, the width of the extended bogie is 4600 mm, and the operating weight is 127 tons.

Small unit designed for medium-sized jobs compared to previous models presented. Height - 14450 mm, total weight with the equipped kelly bar is 34.5 tons. The MDK rotation drive has a maximum rotation speed of 35 rpm; a vertical feed cylinder is built in. Its pressure is 80 kN, and the thrust is 100 kN. The upward speed in the middle operating mode is 4.5 m / min, and the downward speed is 5.5 m / min.

If you use the high speed mode that accelerates the cylinder, then up - 11 m / min, down - 19 m / min. The main winch has a pulling force of 100 kN in the actual position, in the nominal value it increases to 125 kN. The cable is 50 m long and has a diameter of 20 mm.

The maximum speed of the main winch is 60 m / min. The thrust force is 30 and 38 Kn, respectively, in the actual and nominal position. The auxiliary winch is 35 meters long and 14 mm in diameter and has a maximum speed of 45 m / min. A travel speed of 2 km / h is possible due to a more mobile track mechanism, as well as a low operating weight relative to other models. In terms of design, various attachments and functions, they do not differ much from the standard set of past drilling rigs.

In order to most accurately select equipment for construction work, a careful calculation of the amount of work is necessary - this applies to the scope of application. As you can see in the overview of some of the models, certain rigs are designed to drill long wells, which can be used in various industries. At the same time, there are also small units that work more actively and allow you to drill wells faster, although they will be of shallower depth.

As a rule, when renting such equipment, you should pay attention to the technical characteristics. There are times when only one or several parameters are needed, which also plays a significant role. It is impossible not to mention the price that the landlord will demand for the use of the equipment.
