Ground rollers BOMAG BW 179 DH-4 BW 179 PDH-4
Ground rollers BW 179 DH-4 BW 179 PDH-4 are multifunctional machines for sealing polustanova and non-cohesive soils (sand, gravel, crushed stone), and hydraulically binding materials on small construction sites. The operation of these rollers ensures high performance, excellent quality seal the surface with a minimum amount of maintenance equipment.
Primarily on the efficiency of the production process have a positive effect large static linear load and optimum oscillation amplitude vibration device.
The versatility of use of ground rollers BW 179 DH-4 BW 179 PDH-4 provides a possibility to replace the standard smooth Cam roller and lattice in the case of packaging a solid or an intermittent loose ground. Considerable distance between the rollers and the body of the machine allows you to freely maneuver in tight spaces, make the surface treatment along the walls, curbs and roadsides, and quickly change direction. Polyurethane adjustable scrapers protect the rollers from deposition of soil particles and mechanical damage.Rear axle equipped with limited slip differentials that allow you to distribute the efforts between the wheels except their spin.
EVIB measurement system takes measurements of the density of soil by means of special sensors installed on both sides of the rolls. In the case that the maximum level of compaction achieved on a color display a warning icon appears. The necessary information can be transmitted to an external data medium using the USB port.
While working on dirt rollers BW 179 DH-4 BW 179 PDH-4 the operator provides a spacious cabin with vozmozhnostyu all-round visibility of the work prostranstva and outer main working bodies of machines. The dashboard, steering wheels, hand controls raspolagayutsya at a comfortable distance from the adjustable operator’s seat. Cabin ventilation and heating systems thanks to which the user does not feel discomfort even in adverse weather conditions.
