This type of blade is fitted with a particularly sensitive and elastic spring cushion system. It allows work not only in the presence of numerous obstacles, but helps get past them quickly. Intended mainly for use on urban roads and is suitable for plowing both urban and extra-urban roads.
The blade is tilted by two hydraulic cylinders connected by a hydraulic by-pass valve, for greater safety in the event of a collision. A mechanical device enables the blade to oscillate laterally following the pavement. The blade’s sector swivels backward and is raised, and when the obstacle is past, the springs return it to its original position. The springs are adjustable and can also regulate the sensitivity of the mechanical system.
