As we all know, the highest altitude of the Karakoram Highway has reached 4,300 meters, and the slope and curvature are large, so the paving requirements for the equipment are very high! And Xugong asphalt paver RP803 is not afraid of hardship, it is impossible to play on this winding road!
The Karakoram Highway with a maximum altitude of 4,300 meters
140KW high power against 4300 meters high plateau
The RP803 paver is equipped with a 140KW high-powered engine with powerful power and low fuel rate. It is also equipped with a unique plateau configuration, so it can still move freely even at the 4,300-meter plateau.
XCMG RP803 Construction in Plateau
The engine adopts an integrated water tank structure, which is compact in structure and reduces the failure rate of the water tank pipeline. The replaceable cylinder liner structure can be easily replaced and repaired on the construction site; the economy is good, the service life is long, and the discharge is low.
slope? Curvature? Xu Gong is not talking
Customers and friends who have been through the "battlefield" know that Panshan Road has a certain slope and more curvature, which has greatly tested the thickness and width of the paving, and the construction process is more difficult.
On the winding mountain road of Karakorum, the slope of the curve can be difficult to see at a glance
Faced with the ability to climb, with the support of high-power engines and generators, the RP803 paver has the highest climbing ability in the same industry, and the hydraulic telescopic screed has a very wide working width. Flexible, it can spread 3~8.25 meters of various grades of road surface materials, so it is easy to solve the problem of curvature!

Strengthen the intelligent paving operation management function, real-time monitoring and automatic fault diagnosis for the whole function of the whole vehicle. With special suspension device and box structure design, it has good stability and sufficient rigidity to ensure the stability of the work quality throughout the paving width.
Hard core traits win customer respect
Xugong paver RP803 man-machine design is very friendly, hard ceiling design, to provide better protection for operators, safety is greatly improved! Secondly, the console can slide freely throughout the width of the fuselage, providing the operator with barrier-free access to key areas such as hoppers, chutes and work equipment.

Not only that, we use intelligent technology to perform real-time monitoring and automatic fault diagnosis on the whole function of the vehicle; it can visually display various work functions, paving, driving speed, and can be installed around. Moreover, the front and rear covers of the engine and the left and right hoods can be easily lifted up, and the core components of the machine are easy to see, easy to access and maintain.

A needle roller bearing is a special type of roller bearing which uses long, thin cylindrical rollers resembling needles. Ordinary Roller Bearings' rollers are only slightly longer than their diameter, but needle bearings typically have rollers that are at least four times longer than their diameter.Like all bearings, they are used to reduce the friction of a rotating surface.
Compared to Ball Bearings and ordinary roller bearings, needle bearings have a greater surface area in contact with the races, so they can support a greater load. They are also thinner, so they require less clearance between the axle and the surrounding structure.
Needle bearings are heavily used in automobile components such as rocker arm pivots, pumps, compressors, and transmissions. The drive shaft of a rear-wheel drive vehicle typically has at least eight needle bearings (four in each U joint) and often more if it is particularly long, or operates on steep slopes.
