In collaboration with Europoles Swiss, InnoVfoam BV has developed a new concept for fire monitors at height. Conventional steel towers are generally equipped with cage ladders and platforms used in performing mainte-nance work on the monitors. The InnoVfoam-Europoles concept consists of a mast made of pre-stressed concrete with a lowering mechanism fitted to the exterior. The monitor can be lowered using a sled, allowing maintenance to be conducted at ground level.
