MHRB GENERAL INFORMATION

Optima MHRB mobile road blockers are designed especially for entrance points which have a threat of vehicle attack or for the ones that have high security requirements. The main advantage of mobile hydraulic road blocker is their ability to be towed away by any vehicle from site to site very easily by helps of two jacks and four wheels. Even though the attack is from high tonnage vehicles with high speeds, it’s not possible for the vehicle to keep on moving because of the damage given to front, wheels and the bottom of the vehicle.

Drive unit is hydraulic, but in case of power failure road blocker can be lowered or raised with stored energy in the batteries by solar panel (optional). Also, road blocker can be operated manually with the help of manual hand pump.
