Shinjeong Road Sweeper

Shinjeong 6M³ runway sweeper(RS08R)

1. General description

1-1 Features

The runway sweeper vehicle is used for the cleaning of runway, taxiway exclusively. It's capable of sucking gravel, sands, empty bottles, aluminum cans and other coarse things on the middle and side of runway completely without dispersion of dust. The vacuum sweeper superstructure is on the top of a truck chassis cab. Sweeper superstructure contains a vacuum suction device (including blower), sweeping system, water spray system and suction system with castor wheels. All superstructure on the truck chassis is operated by using the switches on the control panel in the driver's cabin and some parts of operation can be made by using the manual levers located on the side of vehicle under the hopper as needed.
