High speed doors

Rapid Roll and Rapid Action Door Repairs

Rapid roll doors cycle hundreds of times a day. Small faults become breakdowns quickly, and a stopped high-speed door usually stops the traffic flow behind it.

What this service covers

The service in practice

Rapid roll and rapid action doors use a flexible curtain, a controller and a high-speed drive to open and close in seconds, maintaining separation between areas while keeping traffic moving. They are found in food production, cold storage, logistics and clean manufacturing.

Access Opening Solutions repairs high-speed doors across Dublin, including curtain damage, crash-out recovery, controller and sensor faults, and the wear that comes with very high cycle counts.

Curtain repair and replacement
Tears, worn wind bars, damaged edge profiles and stretched curtains that no longer track correctly.
Crash-out and re-feed
Recovery after a vehicle strike on breakaway doors, including re-feeding the curtain and re-setting the system.
Controller and drive faults
Inverter and controller error codes, encoder faults, limit learning and brake problems.
Activation and safety devices
Radar, loop, pull-cord and photocell faults that cause doors to open unexpectedly or not at all.
Cycle-related wear
Bearings, belts, guide brushes and side seals replaced before they take the door out of service.

Common faults and warning signs

What we are usually called out to

Door opens only part way

Usually encoder or limit position loss after a power interruption or a strike, requiring the travel to be relearned.

Curtain torn or hanging out of the guides

Impact damage. On breakaway doors the curtain must be re-fed and reset correctly, not forced back in.

Door opens repeatedly with no traffic

Radar or loop detector picking up movement or interference; sensitivity and positioning need adjustment.

Door closes slowly or with a jolt

Belt, brake or drive wear, often preceded by a change in the sound of the door for several weeks.

Controller displaying a fault code

The code narrows the cause quickly — note it before resetting the panel.

Typical causes of failure

Why these faults develop

Extremely high cycle counts, often thousands per week in logistics and production
Forklift and pallet-truck strikes on the curtain and side frames
Dust, moisture and washdown affecting sensors and control gear
Power interruptions causing position loss on the drive
Sensors positioned poorly for the actual traffic pattern

What to do immediately

Before the engineer arrives

Stop traffic through the opening and prevent vehicles driving at a partly open door.
Note the controller fault code and any recent impact before resetting anything.
Do not force the curtain back into the guides after a crash-out.
Where the door provides temperature or hygiene separation, tell us — it changes the urgency.

How we diagnose the problem

Diagnosis before parts

Replacing components without establishing the cause is how doors end up failing twice. This is the sequence our engineers work through.

1
The controller log or displayed code is read first, so the electrical cause is not lost by an early reset.
2
Curtain, wind bars, edge profiles and side guides are inspected for damage from the strike or from wear.
3
Activation devices are tested against the actual traffic pattern, not just bench-tested.
4
Travel limits and safety devices are re-learned and function-tested before the door returns to service.

Repair or replace?

Where repair makes sense — and where it does not

We recommend replacement only where continuing to repair would be unsafe, uneconomic or impossible because of part availability.

Usually repairable

Curtain sections, wind bars and edge profiles
Belts, bearings, brushes and side seals
Controllers, encoders, radars, loops and photocells
Breakaway systems after a crash-out

Replacement usually advised

Curtains with repeated tears across multiple panels
Obsolete controllers where spares are no longer available
Doors specified for lighter duty or narrower openings than the traffic requires

Premises we serve

Types of site

Food production and processing facilities
Cold stores and chilled distribution
Logistics hubs and cross-dock operations
Pharmaceutical and clean manufacturing areas
Car parks and internal traffic routes with frequent movements

Planned maintenance advice

Preventing the next breakdown

High-speed doors are cycle-driven assets: service intervals should follow cycle counts, not the calendar alone.
Photocells, radars and safety devices should be function-tested at every visit in dusty or wet environments.
Impact protection at frame level dramatically reduces crash-out frequency in busy aisles.
Keeping a small stock of site-specific spares reduces downtime on critical openings.

Questions we are asked

Rapid Roll & Rapid Action Door Repairs — FAQs

Our rapid door crashed out after a forklift strike — can it be re-fed?

Most breakaway doors are designed for exactly this. The curtain is re-fed and the system reset; we also check the frame and drive for damage from the impact.

Why does the door open when nothing is there?

Typically radar sensitivity or loop interference. Repositioning and re-tuning the activation device usually resolves it.

Can you service rapid doors alongside our roller shutters?

Yes. Mixed door types on one site are commonly covered by a single maintenance schedule.

Should I reset the controller before calling?

Note the fault code first. Resetting without recording the code removes the most useful diagnostic information.
