Audited Supplier Features:
SR26T/SR30T heavy-duty rubber-wheel type road rollers could compact the laying with the special inflation wheels that are good for the laying. In addition, the compaction could be improved by changing the inflatable wheel load and the pressure.
They are suitable for compaction of base layer, second base layer and asphalt layer and thus preferred for construction of high way, harbor, airport and industries.
Power system
SDEC SC8D156G2B1 turbocharger diesel engines take the advanced technologies from the SDEC and the Austria AVL Company, featuring the excellent performance, high reliability and fuel economy and becoming the mainstream of Chinese construction machinery.
Drive system
Drive system adopts the hydraulic torque converter with automatic stepless speed change and the transmission with power shift, ensuring the steady drive-away, the flexible gear-shifting and the effective transmission both in working and in traveling. In addition, the labor intensity could be greatly alleviated.
Tire structure
Front five wheels and rear six wheels are adopted to realize the overlapped compaction through the wide-base plane, with the max. compacting width up to 2750mm and the specific ground pressure up to 480KPa.
The balance weight decides the compaction, improving the working efficiency.
Adopts the wig-wag machine
Brake system
This system has two independent systems: service brake and parking brake. The former adopts the air-over-oil shoe-type brake, enabling the total braking torque to be 2 times more than the ground friction torque. The latter adopts the abrasive-disc spring brake.
Two independent brake systems enjoy the simple structures, steady braking, safety, reliability and easy maintenance.
Cab
The streamline hood presents the whole appearance and provides the wide view of field through the bilateral operations and the wide-angle exterior rear-view mirror.
The cab with the large bonded glass could give the spacious and bright room. The comfortable and adjustable seats and the brand-new console could deliver the comfortable working environment.
The reasonably-arranged and thoughtful buttons, control levers, switch box and the instruments
Applicable scope
The sprinkler system with the imported water pump could satisfy the different working conditions.
The balance weights could be loaded and unloaded with the forklift to adjust whole-machine weight for different working conditions.
Service and maintenance
Shantui wheel-type road rollers have the excellent maintenance performance and greatly shorten the downtime because of the wide-angle open hood, eight-point centralized pressure-measurement system, maintenance-free battery, real-time monitoring of all the pressures and the temperatures and the reasonable arrangement of diesel tank and the working oil tank, improving the machine utilization.
