Features

 

Driving comfort
Spacious and bright cab features wide view and comfort. Both-side operation can absolutely avoid rolling the curb and the compacting blind corners.
Simple operation
There are two steering wheels, two seats, and two independent control systems for operations. The speed change adopts electric control handle and two-speed gear shift design, which can respectively meet the requirements of compaction and site transfer, together with flexible electronic control operation and comfortable handfeel, greatly reduces the labor intensity of the drivers.
Excellent performance
Adopting the pneumatic tyre to compact the layer will not damage the compacted materials. The compact performance can be improved by adding or reducing the counterweight and changing the inflation pressure of the tyres. Because of the kneading effect produced by the tyre’s elasticity, the material displacement will be produced in all directions, forming even dense surface without cracks, which can prolong the service life of the road. 
Adopt the front wheels swing mechanism. When the machine works on rough road, the mechanism ensures the even ground pressure, which can make the materials be compacted evenly.
The optional international leading infrared tyre heating system realizes the no water sprinkling work of the compactor, and improves the density and service life of the road.
Unique structure
The transmission system adopts the hydraulic transmission with infinitely variable speeds. The start of the torque converter and the speed change are stable and without impact, reducing the shear stress to the road, and improving the compacting quality. The torque converter adopts hydrodynamic drive, which makes the compactor have adaptivity, ensures the diesel engine and the transmission system work under the rated working condition, and prolongs the service life of the compactor.
Safety and reliability
The brake system includes emergency brake and hand brake. The emergency brake adopts air over oil shoe brake system, ensuring the safety, durability and reliability of the machine. The hand brake adopts diaphragm spring brake, it supplements the foot brake and is restricted by the foot brake, featuring safety and reliability.
Leading function
The water sprinkling system has a series of perfect functions such as electric water spraying, power water sprinkling, external pumping, and internal water supplement. When there is no external water source, the automatic water supplement function can supply the counterweight water to the water tank, turning the backwater to flowing water, which avoids the backwater corroding the machine, and meets the requirements of different works.
The adjustable intermittent water sprinkling system meets the requirements of different working conditions, prolongs the service life of the water pump, and avoids stopping work due to the water circuit failures.
Energy conservation and environment protection
Low noise supercharged diesel engine features high performance, reliable quality and good economical performance.
Convenient maintenance
The engine cover is easy to open. Adopt the cover plate structure which can be lifted, which facilitates the inspection, adjustment, and maintenance of the battery, water pump system, and chains.

 

Application

 

Road rollers use the weight of the vehicle to compress the surface being rolled (static) or use mechanical advantage (vibrating). Initial compaction of the substrate on a road project is done using a padfoot drum roller, which achieves higher compaction density due to the pads having less surface area. On large freeways a four wheel compactor with padfoot drum and a blade, would be used due to its high weight, speed and the powerful pushing force to spread bulk material. On regional roads a smaller single padfoot drum machine may be used. The next machine is usually a single smooth drum compactor that compacts the high spots down until the soil is smooth, and this is usually done in combination with a motor grader to get a level surface.
