- The trailer's design allows for a permissible speed exceeding by 20 km/h, meaning that TTMA-70 is actually designed for 90 km/h;
- Does not require special retrofitting of cargo transport for coupling;
- All components are domestically produced. In case of replacement, delivery time does not depend on external factors
- The device has compact dimensions, with a length of 3.5 m;
- High corrosion resistance, all products are hot-dip galvanized;
- Stable and safe activation regardless of the class of the vehicle colliding with the device;
- Compliance with safety requirements specified in GOST R 59291-2021;
- Eye-catching design for road users.
The design reduces the severity of consequences in the event of a collision with a passenger car during mobile and stationary road works. It ensures drivers' and road workers' safety and protects expensive road equipment from damage.
