Revolving Door Repair and Service

Manual revolving doors

Push-operated three- and four-wing doors, where speed control, wing seals, bearings and the collapsing mechanism are the service points.

Automatic revolving doors

Power-operated doors that turn on approach, with canopy or ring drives, speed regulation and a full sensor package covering the drum and the entry points.

Security revolving doors

Doors with anti-piggyback and anti-tailgating detection, usually integrated with the building’s access control and credential system.

Large-diameter and showcase doors

Monumental and two-storey doors, and showcase doors with a display in the centre shaft, where the drive and structure are heavier and the service interval shorter.

A revolving door has four distinct sensor families, and a fault in any one of them stops the door or leaves it unsafe: wing sensors along the leading edge of each wing, end-wall sensors at the drum wall, bottom-rail guard sensors along the floor edge, and entry-point sensors that detect someone approaching or standing in the entrance.

Each group is tested and re-aimed separately. A revolving door that stops repeatedly for no visible reason almost always has one of these misaligned, contaminated or failing — and because the four groups look similar to anyone who is not servicing them regularly, the wrong one gets replaced surprisingly often.

New revolving entrances are installed complete — drum, wings, drive, controls and the full sensor package — and set to the speed and breakout figures their diameter and egress role require. Structural coordination happens early, because a revolving door carries load and needs a prepared opening.

Existing doors are replaced where the drive is obsolete or the enclosure is beyond repair, and older manual doors are converted to automatic operation where the building’s traffic has changed. Replacement is normally staged overnight, with the adjacent entrance carrying traffic in the meantime.

Most revolving doors are locked or parked out of hours, and the night lock is one of the components most likely to be quietly failing. A door that will not lock at closing is a security problem; a door that will not release in the morning is a trading one.

We service and replace night locks, park positions and the controls that switch the door between day, night and slow-speed modes, and test the sequence in both directions rather than only the one the building uses most.

Doors that stop repeatedly and restart on their own, which is almost always a sensor group rather than the drive. Doors that have become noisy or feel rough through one quadrant, which points to bearings, the drive ring or a dropped wing. Doors that have slowed, which is speed regulation.

Others are structural: wings that catch on the drum, seals that have hardened and are dragging, glass that has slipped in its frame, or a night lock that no longer engages cleanly. All of them are serviceable, and all of them get worse if the door is simply switched off and left.

Tell us the door diameter, type and what it is doing, and we will bring the right parts and the right test equipment.
