Snow and ice that accumulated on roofs of trucks and TIR’s during overnight stops on car parks constitute significant hazard for traffic users. The snow charged roof of such a large vehicle could slide off from the roof and its snow and ice debris might be blown down onto the road, causing risk for other road users, damages of vehicles, accidents and hazard of people near the passing by large vehicle. Therefore, it is important to remove the deposited snow and ice from the truck roof efficiently before the departure. Normally, this is carried out manually as an inefficient and laborious activity. The KLIMAWENT designed and manufactured SNOW OUT TRUCK TWINS systems offer perfect snow/ice removal for each TIR roof just within several minutes, by means of strong streams.
