Parking barriers: types, safety devices and maintenance
Quick answer
Choose a barrier on two figures: the lane width (which sets boom length) and how many operations a day it will do (which sets the motor type). Then make sure it has protective devices, CE marking and a maintenance plan: a barrier is a machine moving next to people and vehicles.
Barrier, gate or bollard
- Boom barrier: quick and economical. It manages traffic but does not stop pedestrians or secure the site at night.
- Gate or door (sliding, swing, sectional): closes physically. Slower.
- Rising bollard: for one-off openings where a barrier will not fit; significant groundwork.
A gate for night and a barrier for day is a common combination.
The two figures that decide the model
- Lane width. It sets the boom length. The longer the boom, the slower the opening and the greater the wind load. Long booms may need an end support, or be articulated if the ceiling is low.
- Duty cycle. A 20-space garage is not a pay-on-exit car park. The manufacturer states each model's duty cycle; a residential-grade barrier on a busy entrance fails early.
What goes with the barrier
- Induction loops in the surface: they detect the vehicle to open on exit, prevent closing while it is underneath and close after it passes.
- Photocells: a second protection against closing on an obstacle.
- Obstacle detection in the motor itself: reversing on resistance.
- Signalling: reflective strips, boom lights, traffic light.
- Manual release to open without power.
- Backup battery, if a power cut must not leave anyone in or out.
- Identification: plate, card, phone, remote or intercom (number plate recognition).
Safety and CE marking
A powered barrier is a machine under machinery legislation (Royal Decree 1644/2008 in Spain): it must be sold with CE marking, a declaration of conformity and an instruction manual. In addition, the DB-SUA section of the Spanish Building Code contains conditions for vehicle doors, gates and barriers in buildings, referring to the European product and installation standards. Whoever assembles and installs the set takes on responsibility for its safety.
What to ask the installer for:
- Declaration of conformity and CE marking.
- Operating and maintenance manual.
- A list of protective devices fitted and a demonstration that they work at handover.
Pedestrians
A vehicle barrier is not a pedestrian crossing. If people will walk through, give them a separate, signed route.
Maintenance
The owner is responsible for keeping the installation safe, following the manufacturer's instructions. As a guide:
- test photocells, loops and obstacle detection;
- check balance springs, fixings and boom play;
- check the manual release and battery;
- log every intervention.
More in access control maintenance.
Common mistakes
- A boom too long for the chosen motor.
- No safety loop: the barrier comes down on the second car tailgating through.
- A residential-grade barrier on an entrance with hundreds of operations a day.
- Nobody knows how to use the manual release.
In residential communities
Besides the equipment, an owners' vote is needed: see community garages.
We install and commission barriers with their identification system: parking access control.
Frequently asked questions
What happens to the barrier in a power cut?
It depends on the model: some are released by hand with a key, others run on a battery. Decide in the design what should happen and make sure someone knows how to do it.
How long does a barrier last?
It depends on the duty cycle it is designed for, actual use and maintenance. The manufacturer's data sheet states the expected number of operations.
