The protective cage is a metal structure which consists of a concrete base at the bottom and a metal cage on the top. The connection between these two is done by a hollow beam. The internal dimensions of the cage are 40X24C24cm and inside can be placed a flashing lamp. The concrete base has dimensions 30X30X15cm and offers great stability. The cage is painted yellow so that when placed on a worksite on the road it is visible from great distance to passing drivers. The total height of the whole structure is 1,63m and because it is entirely built in our factory, the dimensions can be adapted to the customer’s needs.
