33000kg asphalt vibratory roller for road base , single drum hydraulic system
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.
Features
Unique structure
Unique cylindrical drum structure features high rigidity and intensity. Short cylindrical bearing with high limited rotation speed provides high load-carrying capacity. The symmetrical arrangement of the right and left vibration chambers avoids the polarization of the vibratory drums.
Easy operation
According to the ergonomics theory, all meters, indicators and buttons are centered on the operation panel. The throttle handle and FWD/REV handle are put on the right side to improve the sense of comfort.
The failure diagnosis screen with alarms can avoid any unnecessary downtime.
The simple and easy lubrication mode ensures an extremely low failure rate of the lubricating system.
XCMG is the first manufacturer to adopt the central engine for effortless maintenance.
Leading compacting performance
The unique hydraulic driving system design and heavy vibratory wheel weight make the XCMG’s roller highly advanced in compaction ability.
Heavy loaded drive axle and nonskid differential mechanism can furthest transfer the output power as well as the tractive force of engines.
Outstanding configuration
The key components are provided by international suppliers (hydraulic pump, motor, drive axle, vibratory bearing and rotating alarm lamp), it also has several engine models for selection to meet different working conditions and customer’s needs.
Multiple functions
The split convex block drum (below 16t) and integral convex block drum (18-20t) can be selected according to the customer’s requirement.
Easy maintenance
The aural and visual alarm device can timely provide the maintenance message to avoid the machine faults and to shorten the down time.
The self-opening engine shield makes the engine and hydraulic pump easy to access to.
