Recently, a fleet of Sany unmanned road machines, which consisted of two pavers, two single-drum rollers, two tyre rollers and one double-drum roller, conducted a coordinated operation demonstration of cement-treated paving and compacting on the main road leading to the Xiong’an New Area, part of the newly named China (Hebei) Pilot Free Trade Zone.
A mobile base station and a control room placed within a short distance enabled remote controlled operation of the seven units. All vehicle operations were automated, with working parameters being set in advance, such as route, paving speed, rolling speed, rolling times and lap width.
Equipped with a 3D leveler and an infrared temperature monitor, the pavers continuously monitor the paving thickness and temperature in real time. The new automated leveling system avoids manual tasks, such as the use of string lines, stakes and averaging beams, which can cause errors.
The demonstration showcased the capability of Sany road machinery to meet the standards for smoothness, compactness and segregation control.
