Features: 1. The drive system used internationally renowned brands of imported hydraulic components; 2. The front and rear wheel hydraulic drive, infinitely variable two tranches, the first drum hydraulic vibration, electrical control delay start-up roller, hydraulic steering, easy operation; each wheel installed below the shaft vibration exciter, making energy more efficiently compacted soil delivered to four tons roller to achieve excellent compaction. And five tons roller, a low position exciter improve the stability of the machine, reducing the risk of the machine tipping over. Articulated joints increases the machine building curve (for example, covers) around operability, and will not destroy the newly compacted ground. The engine control module with diagnostic LED's on the oil, radiator, engine temperature, glow plugs, battery and air filter features such as the ability to monitor. 4 tons roller _ Shandong Jin Heavy Industries (certified) _ Gansu roller provided by Shandong Heavy Industry Machinery Co., Ltd.
