Heald’s HT1-Viper shallow mounted roadblocker is an imposing security barrier which requires an excavation depth of just 400 mm because of its clever folding design. It stands 1050 mm tall when fully raised and comes finished in bright yellow and black stripes as standard for high visibility, presenting a clear deterrent to would-be attackers. The Viper has been both PAS68 and ASTM tested to halt a 7.5 tonne truck travelling at a speed of 80 kph (50 mph) and continue to function afterwards. Raised and lowered by remote push button control, it is also available with Heald’s Hydra control and monitoring system which offers unprecedented levels of interaction through a simple, streamlined interface and can also be accessed by mobile phone, tablet or computer.
