Road Marking Machine “Shmel 12A”, with the increased volume of paint loading, is the ideal solution for marking on highways. 
The use of ISUZU chassis ensures a greater reliability, while state-of-the art equipment helps to achieve top performance.

The LIS system is designed to automatically repeat the old road markings. The system provides repetition of the axial and boundary lines of the road marking for any sequence of cycles. The system is a set of equipment that can be mounted on a Bumblebee class road marking machine. The system works successfully both at night and during the day in bright sunlight.

Advantages of using the LIS system: 
- the use of the system allows you to increase the speed of the markup in compliance with regulatory requirements for quality; 
- allows you to significantly reduce the accident rate (there is no need to move in the oncoming lane when marking the boundary lines); 
- the accuracy of repeating the old markings to a much lesser extent depends on the skill of the driver and operator (especially in curved sections of the road).

Main technical specifications: 
- width of the scanning zone: 600 mm; 
- width of recognizable marking strips: 80 - 200 mm; 
- allowable marking wear for repetition: 70%;

- accuracy of longitudinal repetition: 50 mm; 
- number of spray gun pairs: 2 pairs; 
- working speed of marking: 3 - 20 km / h; 
- total installation weight: from 60 to 120 kg.
