The paving robot of the first generation independently designed and manufactured by ZPMC was assembled for debugging recently.

The robot, supported by two hydraulic flat trailers, is made up of main structure assembly, consisting of mechanical systems of longitudinal gantry, horizontal trolley, lifting system, conveying roller, Knuckle crane and pusher as well as electronic control and hydraulic system. The robot can pick up, arrange and pave precast blocks.

Two knuckle cranes can pick up 4m long and 2m wide precast blocks with the vacuum chuck at the bottom and place them on the conveying roller after adjusting to appropriate height. The arrangement system can combine and arrange them and then the conveying system can send the combined blocks to the horizontal trolley. The trolley can pick up and lift the combined blocks with the vacuum chuck and place on the road surface. Theoretically, the system can pave the road of 12m in the width and 2m in the length within 6 minutes. The paving efficiency of the robot is 5-6 times that of the manual operation.

The project was commenced at the end of March and the technicians completed the whole design within 20 days. Various bases and material departments worked jointly to complete the material purchasing, manufacturing of structures and gears, mechanical assembly and electrical system debugging within 40 days. The robot was sent to the operation site after the disassembly at the beginning of June. The electromechanical and hydraulic engineers are working hard day after night and the robot will be put into the site debugging in the near future.

The smart paving robot will start a new revolution in the road pavement after being put into operation. It will provide environment friendly, detachable and temporary roads for the construction of new districts in different cities, solving problems of time and material waste as well as environment pollution arising out of road digging, asphalt pouring and concrete construction.
