An electric roller gate is door slats linked in a chain, driven by a motor unit, turning around a shaft above the door in fixed tracks. It suits shop fronts, garages, malls, hospitals, factories, and homes. It helps where the opening is large and a ground door is hard to fit, like garage doors, mall fire shutters, and industrial storage.
Care and maintenance usually covers these points:
1. Above the shutter install site, have a reliable fire facility. When boxing or ceilinging the drum below, fit a removable cover plate. On the motor side, leave a 500×500 mm removable service hole for upkeep.
2. For all electric shutters, the travel direction must match the switch box. Especially on first power-up or after a phase swap, first use the manual device to place the curtain at half height, power on, and test until it matches the indicator. Otherwise you damage the limiter and cause reverse roll or over-travel, a real loss.
3. When operating, stand where you can see the shutter move, or accidents and damage happen.
4. Keep the curtain and motor away from acid or alkali solutions to avoid corrosion.
5. Check the running, sliding, and drive parts at least twice a year, and oil as needed, to keep the shutter working.
6. During open/close stop, the shutter should stop in place, not keep sliding. If it slides over 50 mm, check and repair the control electrics and brake until normal.
7. Curtain and rust-prone parts need regular anti-rust, paint, and care. No heavy or hard hits to the surface.
8. If the shutter shakes hard or makes odd sounds, stop and clear what blocks normal travel.
9. The bottom beam upper limit must stay over 200 mm from the bearing bracket bottom, so the brake does not over-travel.
