In road construction, good mechanical equipment maintenance and repair will soon be able to restore the performance of machinery and equipment to extend the life of machinery and equipment, but also reduce the incidence of equipment failure, thereby enhancing productivity and improve economic efficiency.

Correct maintenance attitude

In the road maintenance work, we must correct attitude, improve thinking and awareness, enhance the maintenance of awareness, machinery and equipment…

In the mechanical management system, there are flaws

Construction in highway projects is a long-term process, involving a large range, while many participants. So in the management of road machinery for the emergence of a lot of inconvenience, and then bring the issue of management. At the same time in this regard our mechanism is imperfect, some managers in the management is not enough attention. And even many managers believe that the management of the machinery is only a matter of…

Tire roller with its special inflatable smooth tire to laminate material to compaction, its unique advantages of flexible compaction is rigid roller can not be replaced. It is suitable for compaction of viscous and non-viscous materials such as asphalt concrete, sand and gravel mixture, various stabilized soils and cement concrete (PCC) in construction and road engineering by adjusting the ground pressure ratio of the tire to obtain the best compaction effect. Materials), especially for…
