Electric Motor roller shutter lifting mechanism

The most convenient way to open and close roller shutters is to opt for the electric motor option. A range of electric tubular motors and accessories are available from Advanced Shutter Industries for roller shutters which includes:

  • 240V mains powered tubular electric motors for roller shutters operated by hand-held radio remote control;
  • 240V mains powered tubular electric motors for roller shutters operated by a wall switch or keyed wall switch;
  • Group controls to simultaneously operate a number of electric roller shutters with a single switch;
  • Wind and rain sensors and timers to automatically open or close your electric roller shutters;
  • Back-up power for 240V mains powered electric roller shutters via Uninterruptible Power Supply (UPS), so in a power outage you can still open or close your roller shutters;
  • Free-wheeling safety clutch to avoid roller shutter damage if an obstruction is encountered while closing the roller shutter; and
  • Manual Override mechanisms as a safeguard to allow manual opening and closing of your roller shutters in case of a power outage.

Electric tubular motors for roller shutters are suitable for all roller shutter sizes all the way up to 250kg in weight.


Spring assist lifting mechanism

Roller shutters fitted with an assist spring as the lifting mechanism allow the roller shutter curtain to be physically raised and lowered by hand. The assist spring balances the weight of the roller shutter curtain and makes lifting and lowering the roller shutter easier and safer. Spring assist lifting mechanisms are suitable for roller shutters starting from 1.0 m wide. For commercial roller shutters wider than 2.7 m fitting a second assist spring is highly recommended to avoid axle torsion and ensure even lifting. In any case, we recommend use of an electric motor for roller shutters weighing more than 60 kg or wider than 3.0 m.
