ZTU-300 scraper


The ZTU-300 scraper is a self-propelled machine used during construction and maintenance of the railway track. With its help, it is possible to e.g. form the ballast heap, scrape the ballast from the track onto the shoulder, move ballast from one side to the other etc. The scraper's propulsion is done by a diesel engine of 160 kW power, which cooperates with an electro-hydraulically controlled four-gear transmission. This allows independent movement at up to 80 km/h, whereas the hydraulic propulsion gives a speed of 1-10 km/h. The working components of the machine are: central plough, side ploughs, scraping device with a rotary brush, two lateral conveyors, stacking belt and a ballast container. Driving and working unit movement control is done from a spacious, ventilated and heated cabin.
