Ground rollers BOMAG BW 211 D-40 BW 211 PD-40

Rink clay BW 211 D-40 is designed to seal polustanova of soil, sand, gravel, stone chips and hydraulically binding materials. Rink clay BW 211 PD-40 in turn is used for compacting the soils with high water content. The machine is mainly used for medium and large construction sites. The operation of these rollers can significantly reduce maintenance costs and preventive maintenance of the equipment.A high level of performance and excellent surface quality is achieved due to the large static linear load and optimum amplitude and frequency of vibrations of the vibrating device. All the details of ground rollers are made of high-strength materials, which greatly increases their durability and ensures long service life.

The special design of the smooth rink roller BW 211 D-40 prevents the occurrence of bumps and other defects on sealing surfaces Smooth drum easily becomes studded with the help of special devices. With two sides of the rollers are equipped with scrapers that protect the surface from sticking of soil particles, so rollers BW 211 D-40 BW 211 PD-40 can be used during operation under the most adverse conditions. The main working body of the soil of the rink BW 211 PD-40 is a Cam drum, having special tabs for compaction of loose soil.

A significant gap between the main body rollers and rollers provides good maneuverability even in confined spaces. The details of the rollers, which during the production process are constantly in contact with the surface of the earth, made of high quality stainless steel.

Data rollers are characterized by easy control, even inexperienced users are not required to undergo a special training course. All icons and symbols that appear on the instrument panel displays are common and understandable for native speakers of any language. The spacious cabin has all the fixtures for the convenience of the operator during operation of ground rollers BW 211 D-40 BW 211 PD-40. Waterproof and has a sunscreen allows not to stop the production process, even under the most adverse weather conditions.The operator almost does not feel the vibration while on the jobsite. Given the possibility of a full circular view of building object and working bodies of the outer rollers.

The body of a machine, made of sheet steel, are completely sealed, which protects the engine and internal parts from mechanical damage and clogging. Special EVIB system produces accurate measurements of the density of the treated soil layer using two sensors. When it reaches the maximum level of summarization, the display displays warning icons. The results of performed operations are stored in the system memory.

Rollers are equipped with four-stage fuel filters that prevent the ingress of low-quality substances into the engine. Rear axle equipped with limited slip differentials that allow you to distribute the efforts between the wheels except their spin. Thanks to an improved system of supply lubricating fluid increases the durability of main machine parts.
