Road Machinery Challenges the Impossible

From large-scale hydroelectric project to the “ridge of the world”-Qinghai-Tibet Railway, from Beijing ring six road project to the World Cup and Olympic Games in Brazil, Sany road machinery never stops challenging the impossible and making wonders that cause attentions of the world.

Working in the plateau is one of the toughest challenges for road machinery. The oxygen deficit and severe cold made the engine hard to start and appear frequent flameout in the Qinghai-Tibet Railway construction, which is located in the altitude of over 5000 meters. Engineers took the initiative to research and develop the rollers, motor graders and pavers that were specially used in plateau. These customized products had great climbing capability and can be used in the low temperature with high efficiency.

Beijing ring six road construction was one of the key parts in 2008 Olympic Games project, its high technical standard and construction difficulty made a record in China road construction. 7 Units of Sany road machinery including motor grader, roller and tire roller were used in this great project.

Algeria East and West Highway is the longest highway in Algeria, which is located in heavy hills with gullies and ravines. Not limited to steep terrains, the construction area is covered with marlstone, which is called “mine field” by the road builders. As the main force, SANY provided 193 units of equipment for this project including 56 units of rollers, 32 units of motor graders, 5 units of pavers and so on. Rio de Janeiro is the host city for the 2014 World Cup and 2016 Olympic Games. In order to welcome the two international events, Brazil spared no efforts in building the World Cup stadium and Olympic Village. About 100 units of hydraulic rollers were used in the two world projects.

With the belief of “Quality Changes the World”, Sany never stops producing more innovative construction equipment with advanced technology and commits to making more contributions to the world. Sany road machinery will continue to challenge the impossible and create more world wonders.

Motor Grader Applications and Maintenance Guidelines

Motor grader plays an important role in leveling and grading work in earth moving and foundation. It is widely used in large-scaled ground surface leveling, such as, highway and airport construction. The grader is a great tool to assist other machines complete working, it can be used alone or combined with other machines. In the road building, the grader is indispensable, especially in the finishing stage, where the grader will spread and flatten the soil to create a well smooth, wide-ranging and level surface, making a strong and stable foundation for the road construction.

Motor grader is a kind of earth moving and foundation machine with high speed, high efficiency, high accuracy and multiple functions. It can be used in road leveling, trenching, slope cutting, bulldozing, snow removal, earth scattering and mixing, land clearing and so on. It is an important part in mineral construction, road repairing, water conservancy and farmland improvement. The road bed is the foundation of the road surface, an important part in road construction, it bears the traffic loads, so the road bed must have high strength, stability and durability, which is the daily work of the grader, simple but tough.

Hydraulic oil is one of the most important factors that need to be maintained well in the motor grader daily maintenance. The hydraulic oil is not only the transmission medium but also the lubricant, which is used to seal the parts, and the hydraulic oil bears the role of heat dissipation as well, therefore, it is very important to keep the hydraulic oil efficient and reliable. Qualified hydraulic oil features proper viscosity, anti-rust, antioxidant and low volatility. The hydraulic oil should be kept clean and avoid pollution, thus providing the machine the most purified power source.

Motor Grader Daily Maintenance

Motor grader is used very often in the road building and leveling. It is troublesome when the machine breaks down during the working process under a tight working schedule. In case of emergency, construction equipment daily maintenance is very important to keep the machine in a good condition all the time. The followings are some guidelines about the road machinery daily maintenance.

Engine is the heart of the construction equipment, the machine will stop working if the “heart” goes wrong, so more attentions should be paid to the engine of the motor grader. Before starting the engine, we should check the fuel level to make sure the machine can operate normally. What is should be noticed is that the fuel should not be filled too full since fire will be caused if the fuel overflows under high temperature. Check the fuel pipe and fuel tank to avoid any leakage. And the remaining water and other sediment should be discharged every day to keep the fuel tank clean and purified. The coolant should be added enough to keep the machine work normally. The radiator should be checked regularly to keep the machine cool and the damaged radiator should be changed immediately to keep the machine operate smoothly.

If only you master the above maintenance guidelines, your motor grader will operate in high efficiency and create more profits for you.
