The thickness of the special line coating layer is 1.5-4MM; a variety of funnels can be selected, the width of the line is 100mm, 150 mm, etc. generally, it can be used to replace the manual push type hot-melt line marking machine, with simple operation high construction efficiency. The self-propelled hot-melt marking machine adopts the German intelligent program control humanized control panel, is equipped with a stepless speed change walking system that can move forward backward freely. Copy greatly improves the construction efficiency. It is the one hundred key equipment for the construction of hot-melt marking line. It is used together with the hot-melt kettle to complete the marking construction. The machine uses a cast iron marking bucket to ensure that the marking line has the same edge, head, thickness beauty The landing knife can adapt to different road conditions. The machine is equipped with a stepless speed change walking system, which can greatly improve the construction efficiency, is suitable for the hot-melt construction road with gradient. High difficulty marking construction can be completed by cooperating with hot melting kettle. The equipment adopts a special cast iron marking bucket to ensure that the road surface is marked, the glass bead disperser is equipped with a speed regulating buffer device. The construction quality of the marked line is high, the speed is fast, the operation is flexible, the maintenance is simple so on.
