XD121/131 Tandem vibratory roller Description: The XD121/XD131 dual-drum vibratory roller is designed specifically for the compaction of aspect concrete and cement concrete surface courses. It can also be suited for compaction on small and medium base courses, sub-base courses and fills. A combined high working efficiency is given into full play especially when the machine is used together with tarpe players. So it is by no means a kind of ideal equipment for high-grade highways, modern airport, targe-scale, parking lots applications. Etc. Main features: The patented crab-type travel mechanism and double articulation steering can ensure the front and rear drum stagger for 200mm (two directions). This design is benefit for road edge compacting and curve road compacting. The front and rear drum are driven by two hydraulic motor which is pearled connected. Because the plunger pump is controlled by reversible handle. The stepless speed change can be ensured along with the simultaneously driving. Vibratory device has two gears of amplitude electromagnetism variable plunger pump on distribution box provide pressure oil to the vibratory motors of front and rear drum. The vibrate simultaneously but also can vibrate singly. As the full hydraulic transmission and full electro-hydraulic control technology has been adopted on this machine. The operation to this machine is very simple. Except the control to reversible handle and engine. All the operation can be realized through purchasing some switches. The instrument panel and seat can relate within a certain range and have a correspondingly anchor parts. So the operator can have a good view to the all kinds of compacting condition. With the 3-grade vibration reducing system, the seal can provide the operator a comfortable operating environment. The Cummins 4B TAAJ9 diesel engine meets the Euro II emission standard, with the powerful engine. The roller can perform to its best under the heavy duty condition. The new type interval sprinkling system put an end to some common troubles, for example, the water can perform to its best under the heavy duty condition. The water tank is made from plastic, which is avoid of the pump jam caused by material shading off.
