Abstract
An air brake security locking system retains semi-trailers in a fixed position to prevent theft and is connected to an air brake line of the semi-trailer. The system includes a battery-powered valve which isolates air lines within the braking system at a low-pressure condition, thereby maintaining continuous braking of the wheels. The system includes a locked control box to secure and protect a user interface used to activate the system by entry of a numeric code using a keypad or by using a bypass key lock. A wireless remote actuation device is also utilized to activate the system from a distance. In a deactivated state, the system allows the braking system of the semi-trailer operates as normal. In an activated state, the system securely applies the spring brake units of the semi-trailer preventing movement and possible theft.
