SWING GATE LB 312
The swing gate LB 312 is designed for controlling access of people and transport of goods in work places, office buildings and leisure centers. The gate`s entrance is wide enough to be utilized as one of the ways of evacuation. Depending on its function, it is available in three versions: mechanical only (M), electromechanical with spring closer (D) and evacuation with automatic opening (E). There is no servomechanism in the gate’s wing, thus it is recommended for installation in a light traffic environment.

- All inner steel elements are galvanized, both the polished cabinet and the wing is made of acid-resistant stainless steel (type 1.4301).
- Two-way mechanism enables the use of one gate both for entering and leaving with a possibility to block backward movement (in prohibited direction).
- Available with wings of various lengths.
- Spring or manual wing’s drive mechanism.
- Special damping element increases the mechanism’s durability and guarantees that a gate functions very quietly.
- Gate is fitted with an emergency stop that allows even the locked wing to rotate at a torque of over 550 Nm.
- Suitable for outdoor use in the areas with no exposure to precipitation.
- No external flange and anchor bolts concealed inside the cabinet allow the use of the entire width of the gate and protect the pedestrians from tripping.
- An economical version of the gate with no drive mechanism or automatic blocking of the backward movement in prohibited direction.
Operation
The blocking system is released by the opening impulse set by the steering mechanism and the wing is tilted 90° to the right. The wing is tilted as long as the external impulse lasts. When the impulse is interrupted, the wing returns to its prior blocking position and the passage is blocked. If the next impulse is given while the gate is closing, the wing changes its direction and opens again.
Maintenance
- Bolts lubrication: once a year or every one hundred thousand passages.
