Auto Mate Systems Ltd supply and install manual, rising arm, vehicle barriers up to 8m long. They come complete with a counter balance weight and locking post so the manual barrier boom can be locked in both the up and down position by use of a padlock. The boom is extruded tubular aluminium and is fitted with two stop signs to improve visibility. The ideal place for fitting a manual barrier is on a small industrial park or road which needs to be secure out of hours so a small number of users can have a key to the padlock so that the first person in can unlock and raise the manual barrier and last person out may lower it and lock it down. This barrier is often called a rising arm barrier. We also supply a swing arm barrier which is actually a swing gate, please look at our manual products for information on the swing arm barrier.
