The Tremix spreader waggon TV 830 ensures an even distribution of the Tremix Hardtopping granolithic concrete material. The TV 830 is of robust design and can be handled by one operator. The Hardtopping material is distributed in batches, easily regulated from the handle. The TV 830 is provided with a screen roller, width 830 mm, instead of wheels. It is therefore not necessary to use any wooden rails on the concrete surface. The roller carries the weight of the machine at the same time as it presses the material upon the concrete surface. The TV 830 is provided with link wheels that are lockable laterally in order to make it possible to move the machine longitudinally along the casting bays. The receptacle for the Tremix Hardtopping material contains 2 bags. The bags can be opened with a knife integrated in the carriage. The TV 830 is provided with a dust protection.
