Frequently Asked Questions

The following are a few of the most frequently asked questions we get asked.

1. What is the difference between Speed Gates, Speed Lanes and Paddle Gates?

Speed gates is the name most used for a verity of pedestrian entrance controlled gates there are many others. Speed gates and speed lane are defined by the type of drive mechanism they use. There are two basic types of drive mechanism:-

  1. Swing type - Have arms that open in the direction of travel. Because of the arms movement they are sometimes call paddle gates as well as speed gates and speed lanes.

  2. Retractable type - Have arms the retract back into larger cabinets, sometime known as flap gates because the arm is cheese wedge shaped or sliding gates because its a full panel.

2. Do Speed Gates, Speed Lanes and Paddle Gates open fast?

All version of speed gates open and close, retractable open slightly more quickly than swing arms. The actual passage thought-put speed is determined by how fast the access control system can valid the card/token and give the open command. Then it depends on how quickly the user can present the card and pass through the lane.

To increase the passage flow rate all Evolve gates have a so called ''Stacking'' function. This means we can remember up to 99 valid open commands. Then this function is turned on its typically set to 5, so the lane will remember 5 valid open commands and stay open until all 5 users has passed.

 

3. Can trolleys, wheelchairs large bulky items be use with speed gates.

Some retractable flap speed gates only have up to 550mm opening in which case they can be used in congestion with a DDA swing gate. Retractable sliding speed gates are typically limited to 900mm opening due to the cabinet size. Swing or paddle gates speed gates can normally have up to 1200mm which are ideal for sports wheelchairs and fire regulations.
