Direct drive (standard): Maintenance-free completely oil-sealed, encased worm drive safety gear mounted directly on the steel shaft of the axis, which vastly reduces the installation and maintenance work involved, compared to other configurations.
Integrated failsafe device can be installed in any position, requires no maintenance and is self-monitoring, together with an encased limit switch flanged onto the gear with accurately adjustable end and safety end switches.
Emergency crank or manually operated chain for quick release if power fails. All electrical lines are plug connected to the drive. Operating voltage: 400 V three-phase AC. Drive tested by TÜV and VDE.
Sprocket drive with failsafe device (made to measure): Maintenance-free completely oil-sealed, encased worm drive safety gear with limit switch, including emergency crank or manually operated chain – as for direct drive but including the necessary sprockets made of steel and the matching chain to transfer the force from drive to roller.
This must be installed together with the TÜV-tested failsafe device to stop the door falling, even if the supports fail.
Roller: Steel, base coated, size complies with permissible bend of 1/500 of its length, minimum diameter 168 mm to wind the curtain up better.
Bracket attachment: Plugged, bolted or welded on. If welding, fasten it to the on-site substructure or previously installed anchor plates in line with our offset plans.
Self-aligning ball bearings: Large, for mounting the roller, mounted on brackets.
Emergency operation: Emergency chain, operated from the floor.
Assembly / electrical installation: Our installation conditions are based on existing DIN regulations. Accordingly, all routing and connection of any electrical parts must be provided on site in line with our circuit diagrams, as must the power supply and wiring of parts with the necessary cables. A backup fuse and lockable main switch must also be provided on site.
