    • A mobile barrier system comprises a vehicle having a chassis, which is provided with wheels, as well as a barrier, which is coupled to the vehicle and can be transferred between a folded state and an unfolded state. This vehicle is realized as a motor vehicle having an integrated motor, a drive line between motor and wheels, and having one or more steerable wheels. Such a barrier can be quickly and easily displaced, such that a flexible deployment is made possible. In particular in the guidance of crowds of people, or the controlling of disturbances, the high mobility of the barrier system is an important advantage.
    • 移动障碍系统包括车辆,其具有设置有车轮的底盘以及联接到车辆并且可以在折叠状态和展开状态之间传递的障碍物。 该车辆实现为具有集成电动机,电动机和车轮之间的驱动线以及具有一个或多个可转向轮的机动车辆。 这种障碍物可以快速而容易地移位,使得可以灵活部署成为可能。 特别是在群众人群的指导下,或控制干扰,障碍系统的高流动性是一个重要的优势。
