This equipment employs a high-capacity lithium-ion battery with stepless variable-speed drive, delivering robust and sustained power with smooth operation. Capable of bidirectional self-propulsion at constant speed, it is ideal for extended continuous line marking, significantly reducing labour requirements. The intelligent operating system integrates mechanical, electrical, hydraulic and pneumatic functions, automatically controlling parameters such as line profile, agitation and mixing ratios. The extrusion system utilises a multi-layer composite extrusion chamber, ensuring seamless line profile switching with uniform, non-adhesive markings. Equipped with a rapid cleaning system, it facilitates efficient and convenient colour changes during operations. The electrically controlled aluminium film spreader ensures uniform distribution. The unique marking structure offers wear resistance, environmental friendliness, hydrophobic reflectivity, and reduced paint consumption. Additionally, it incorporates an integrated electrical control system enabling one-touch line pattern switching; adjustable steering provides light and agile manoeuvrability; pneumatic glass bead spraying delivers more uniform coverage and stronger adhesion. Overall, it ensures efficient, stable, and high-quality construction performance.
