Electrical Type Rolling Shutters are operated by using a range of electrical actuators capable of operating shutters of all sizes. They are made up of selfbraking worm gear with hollow shaft, integrated limit switches, integrat- ed safety brakes with overload protec- tion. Operationally, these shutters are relatively easy, hassle free and extremely safe and operate by integrating the control accessories like push-button, key selector or remote controls. During downtime, the option for manual operation is also available.
