Mobile crash barriers in roadworks clearly enhance traffic safety. Their containment capacity prevents road users from leaving the carriageway and colliding with oncoming traffic, while also providing safe working conditions on site.
The mobile crash barrier ProTec 51 with a very narrow structural width of only 24 cm and a weight of 28.7 kg per meter is an ideal addition to the proven portfolio of ProTec products This is currently the narrowest and lightest mobile road restraint system in the ProTec family and is based naturally on the well-known benefits of the tried and tested ProTec 100/120/160 systems. Due to the small footprint, ProTec 51 is ideal for traffic safety in ZTV-SA applications A, B and D that is between roadwork site and oncoming traffic, between roadworks and flowing traffic as well as between roadworks site and opposite flows of traffic.
No matter what your particular application is, mobile crash barriers in the ProTec family always put you on the safe side!
