PROMStahl offers a variety of operators for powering sectional doors. A manual system is ideal for doors that are not used frequently, whereas an electrically powered system with touch control is best for doors that are in constant use. Depending on the door configuration and your requirements, there is always a type of drive to suit your needs. All our drive systems and operators meet the European EN-13241-1 standard.
Pull cord – manually operated
If your door is smaller than 16 m² and you use it only sporadically, then your best option is the pull-cord mechanism. However, the system requires physical exertion (1:1 ratio) and there is a risk the door will not open sufficiently which may result in damage.
Chain hoist – manually operated
The chain hoist requires less physical exertion than a pull-cord (1:4 ratio). The system – suitable for sectional doors up to 30 m² – ensures that the door can be secured in the uppermost position.
Deadman control unit – electric
This system is an excellent choice when a door is used infrequently. One push of the button is all that’s needed to open the door, although you have to keep it depressed to close the door. This enables the person operating the controls to keep an eye out for any dangerous situations that may arise while the door is closing.
Touch control unit – electric
If the doors are in constant use then go for a touch control system. The door raises or lowers automatically to a set position, which can be electronically adjusted without having to keep the button depressed. An obstacle detection system is built into the door’s bottom seal.
One touch with remote control
The touch control system is also perfect for remote operation and can save a lot of time because it allows the forklift driver to remain seated while the door is opened or closed remotely. This option includes a stationary photoelectric safety sensor, which is fitted to the door.
Touch control with remote control and high speed motor
If the doors are in constant use then go for a touch control system. The door raises or lowers automatically to a set position which can be electronically adjusted without having to keep the button depressed. An obstacle detection system has been built into the door’s bottom seal.
