Exxaro coal is a critical supplier of coal to some of South Africa’s hungriest power plants. Turnstar a récemment remporté le contrat pour la fourniture de deux barrières de circulation à grande vitesse à énergie solaire pour sécuriser l'une de leurs mines souterraines critiques. The vehicle barriers were each supplied with their own adjustable mounting pole which allows for angular adjustment depending on the season, as well as a solar charge controller which powers up the batteries. The two 4.5m barriers are manufactured from powder coated 3Cr12 stainless steel and use a BLDC motor with planetary gearbox which enables high speed and consistent operation. Pour la sécurité, the barrier has a dual channel loop detector and the motors ‘hall’ sensors can detect a collision within milliseconds, allow the barrier arm to reverse in the event of a collision.
