30 ton pneumatic tire road roller XP303
XP303 tire roller is a large tonnage tire roller produced according to market requirements. It uses pneumatic tires as working devices to compact the pavement materials. It is mainly used for asphalt pavements, foundation layers, sub-base layers, dams and fill Compaction operations such as engineering are ideal compaction equipment for the construction of high-grade highways, airports, ports, dams and industrial construction sites.
Adopt Shangchai SC7H180.2G3 electronically controlled diesel engine, which has high reliability and fuel economy, low noise and low emissions to meet the national phase III standard.
The hydraulic torque converter and power shift transmission with stepless automatic transmission are used to make the roller have automatic adaptability. When the external load suddenly increases, the roller can automatically decelerate and increase the traction force; when the external load decreases, the It can automatically reduce traction to adapt to changes in external load, improve the smoothness of compacted transmission, and ensure that diesel engines often work under rated conditions.
When the roller is turning or the driving wheels have different driving conditions and different ground adhesion coefficients, they can prevent the wheels from slipping and slipping.
The parking brake is pneumatically controlled.
The volume of the gas storage tank is doubled, and the reserve factor is larger, ensuring safety and reliability, especially suitable for frequent braking conditions in mountainous areas.
Exclusive domestic use of dual-circuit braking system, higher braking efficiency, fast response speed, short braking distance and higher reliability.
Adopts all-wheel braking technology to ensure the safety of the whole machine, especially suitable for mountain conditions.
The fuselage uses a box-type overall frame. The front and middle sides and the lower part of the frame are counterweight water tanks, which can also be used as sprinkler water. Each part of the fuselage is designed with service holes and a flip cover to facilitate the maintenance and maintenance of various components.
The configuration of an intelligent intermittent sprinkler system can not only greatly improve the reliability of the sprinkler system, but also minimize the impact of the sprinkler operation on the quality of the construction road surface.
The optional intermittent oiling system can widely meet the needs of domestic users, save manpower and material resources, and effectively reduce the adhesion of tire tread asphalt and improve work quality.
Optional centralized inflation.
