Barriers And Gates Technical Data

Swing Gates
The operators are either electro-hydraulic or electromechanical and there are a range available depending on the size of the gate and the frequency of use. The operators can either be mounted hidden under the gate stile or be mounted onto the gate post with a drive arm connected onto the gate. Underground operators have the advantage of not affecting the aesthetics of the gate design and also can accommodate between wall installations. With gate post mounted drive systems the geometry of the respective positions of the motor mounting and the gate hinge point is critical and must be considered when designing new installations. These systems can be single or pairs and the swept area of the gate leaf must be clear and not inclined upwards.

Sliding Gates
Both types of sliding gate use electromechanical units with a rack and pinion drives and can be single or pairs of leaves, the critical area in this case being to either side of the opening. With cantilever gates the side room would normally be at least 150% of the gate leaf width. Sliding gates are the best option for busy commercial installations.

Controls
Many types of customised controls are available, remote operation from vehicles, key pads, controlled opening from a house or security hut, and there is also a range safety devices to prevent accidental closing causing damage to vehicles or injury to pedestrians.

Traffic Barriers
Manually or electrically operated barriers available to suit most road widths, and with the complete range of activation and safety devices, customised to suit the client’s movements.

Bollards
Automatic bollards which are mounted underground and rise to prevent vehicular access, perhaps to a parking area or for security reasons, and these can be selected as a visual barrier to stop a car taking a parking place or heavy duty units capable of withstanding the impact of a large vehicle.
