10-meter paver construction case|SAP90C-10S helps Hunan Changzhu Expressway rejuvenate!

Project Background

As an important traffic artery connecting Changsha and Zhuzhou, Hunan Changzhu Expressway carries a huge traffic flow. In order to ensure road traffic safety and improve driving comfort, the pavement overhaul project of the expressway will be launched at the end of 2024, and Sany SAP90C-10S will participate in the paving construction of a total of 400,000 square meters of asphalt middle and upper layers, which greatly improves the construction efficiency and quality.

SAP90C-10S equipment highlights

Smart construction, smart and convenient

Driver assistance systems

The industry's first asphalt paver with an assisted driving system automatically identifies curbstones and lime lines through visual recognition and depth algorithms, realizes automatic steering, lane keeping and equidistant welt paving, and reduces 1-2 construction personnel;

A new generation of inverter power generation intelligent heating system, with fast heating, intelligent temperature control and heating functions while construction, heating to 100°C in 20 minutes;

The height difference and camber of the screed, and the electronic control adjustment of the ceiling lifting, can be quickly adjusted in place. One-key cleaning function, easier operation.

The control is sensitive, smooth and compact

Real shot at the construction site

A new generation of membrane button control system, equipped with the third-generation controller, shortens the operation cycle to 5ms, significantly improves the control sensitivity, and strengthens the sense of control;

The industry-leading 170mm large-diameter 3-layer telescopic screed, the unique torsional telescopic screed, and the high-strength steel plate are used for the key structural parts, which increases the torsion resistance by 30%, and the comfort plate structure is stronger and the deformation is smaller;

The 8 motors drive the screed vibration and vibration system independently, and the forced synchronization technology is adopted, and the motor speed error is ≤5% to ensure the same compactness. It is equipped with a telescopic material guide device to reasonably control the width of the trough, reduce the resistance of the screed, and further improve the flatness of paving.

Abundant power, stable and reliable

Cummins engines

It is equipped with 154KW Cummins B5.9 engine (optional 162KW Cummins B6.7 engine), which fully meets the needs of asphalt paving construction;

Equipped with a 1-point 5 gearbox independently developed by Sany, it balances and matches the load and has a long service life; Closed-circuit hydraulic system, three-stage filtration of hydraulic oil, improve cleanliness, longer service life of the pump set, more reliable; The sub-compartment diversion power cabin has smooth airflow, air volume of 5 cubic meters per second, and strong heat dissipation capacity to ensure stable and reliable 24-hour continuous construction.

The successful implementation of the 2024 pavement overhaul project of Hunan Changzhu Expressway is not only due to the exquisite skills and rigorous management of the construction team, but also inseparable from the strong support of Sany advanced construction equipment. In the future, Sanyi Road Machinery will continue to uphold the concept of "quality changes the world", continue to develop and promote smarter, more environmentally friendly and more reliable construction equipment, and contribute more to the road construction cause in China and even the world.
