Most gate motors come with built in locking however often this is limited by the length of the gate. SEA motors are particularly strong in this regard but we will still recommend locking devices for high security sites. There are 3 main types of lock, the latch lock, hook lock and magnetic lock. Each has strengths and weaknesses which we will explore in this section.
Powered latch lock – These are widely used within the industry to secure an electric gate, by the action of a rotating beak. Latch locks are available with optional internal or external cylinders (12v supply taken directly from control panel).
Powered hook lock – A high security version of the latch lock, with the rotating catch hooking onto a peg for additional strength. These bolts are rated with a 2000kg holding force, and are provided with external and internal releases as standard. (12v supply taken directly from control panel).
MAG LOCKS –
Magnetic locks – These are particularly useful for timber gates that are prone to expansion or large gates that have a tendency to move, due to leaf length and flexibility. They are rated with a 1200lb holding force and are often used in fail-safe situations.
142 DRIVEN BOLTS
Driven bolts – Simple mechanical bolts for paired gates, which centrally secure the first closing leaf to a floor stop. Two versions are available, suitable for domestic and industrial applications.
