Gate Operator Model
Gate Operators are also known as a sliding gate opener, electric gate opener or gate motor - they power our customer's Sliding Gates to open and close along ground-surface rails. SUNBEAM Gate Operators consist of three models, differentiated by transmission type (chain or gear rack) and gate installation (operator fixed to ground or fixed to gate).
GA Fixed to Ground Chain Type
The GA Gate Operator is fixed to the ground and employs a 3-sprocket transmission, pulling on a chain attached to the gate, moving it in both directions. A limit switch (on Gate Operator) and limit bumps (attached to gate base) limit the extent of gate movement in either direction.
GB Fixed to Ground Gear Type
The GB Gate Operator is fixed onto the ground and employs a gear rack, which is attached to the gate and runs the entire length of the gate. A single sprocket on the gate operator turns and pulls the gear rack in both direction. A limit switch (on Gate Operator) and limit bumps (on gear rack or on covering of gear rack) limit the extent of gate movement in either direction.
GT Fixed to Ground Chain Type
The GT Gate Operator is fi xed to the gate itself and uses a sprocket att ached to a circular chain which turns the axle/wheel assembly underneath, which then pulls the gate along the tracks laid onto the surface ground (the tracks run twice the length of the gate). A limit switch is att ached to a porti on of the gate and stops the gate when it hits either limit bump fi xed onto the ground at both ends of the tracks.
