Thank you for your cooperation in the installation of the belt conveyor on the Gaikan Expressway (Outer Ring Road).

In order to further enhance safety, we will introduce a mobile protective fence (load zipper system) in some sections of the lane regulation.

1 Overview of mobile guard fence (load zipper system)

The Road Zipper System is a system that allows you to move a concrete guard fence using a dedicated guard fence switching vehicle, and freely and safely change the construction lane regulation range according to the road congestion situation. It is possible.

By separating the traffic lane from the work zone with a concrete guard fence, the safety of the customer and work within regulations is improved.
