Serco SL60 Series powered vehicle restraints provide automatic push-button activation with advanced electronics and standard LED communication systems for increased dock safety and security. Driveway or wall-mounted, SL Series powered vehicle restraints engage the rear impact guard of a vehicle and hold it in place during the loading and unloading process. The restraint is raised and lowered automatically at the touch of a button, and the exclusive sensor bar automatically senses and communicates the contact between the restraint and the trailer’s rear impact guard. The programmable logic controller (PLC) offers more flexibility to meet the evolving needs of your facility. The SL60 will auto-reverse if no rear impact guard contact is made, signaling dock workers via the LED lights to ensure maximum operational safety.
