Product Introduction The small rough-making machine developed by our company is a type of pre-treatment equipment for bridge deck and road pavement, which can remove coat marks and concrete laitance efficiently. By operating slight rough-making treatment for the road pavement and removing old surface course, the cohesive force is improved, so that the pre-treatment on surface for the construction of slurry seal coat and water proofing of deck is carried out. Main Performance Characteristics 1,Small rough-making machine uses high-speed rotating hard blade to impact working face; by choosing different blades, it can be applicable in different surface rough-making treatment. 2,The adjustable deep locking device can keep the depth of rough-making consistent. 3,The safety switch can rapidly shut down the engine. 4,Dust collecting interface is provided for dust collecting equipment, which is environmental-friendly. 5,The blades, with simple structure, can be installed or uninstalled within 5 minutes. Main Technical Specifications Type: LM242 Power: 25hp Rough-making width: 242mm Maximum single-rough-making depth: 3mm Appearance dimensions:1500×800×1200mm Weight: 325kg
