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:
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.
