Road Roller YZK12HD with RexrothDescription of Road Roller:
A road roller is a type of construction machinery/construction equipment. Ii is usually applied to compact soil, gravel, concrete, or asphalt in the construction of roads and foundations.
Structures of Road Roller YZK12HD with Rexroth :
1. Road Roller YZK12HD with Rexroth is equipped with DongFeng Cummins engine
2.Double frequency & Double amplitude and super centrifugal force creates strong compacting effect
3. PD model are comprised of 3 segments and are dismantled.
4. Hydrostatic travel and vibration drive, and stepless speed regulating.
Features of Road Roller YZK12HD with Rexroth :
1. Reasonable configuration, reliable performance, and high working efficiency hydraulic components
2.Operator's station is designed for comfort and safety such as fully-adjustable, suspension-mounted operator's seat.
Applications of Road Roller YZK12HD with Rexroth :
This Road Roller YZK12HD with Rexroth is widely used to compress the surface being rolled to ensure a smooth, even result on the construction site such as road-making, runway of the airport, and building.
