Folding Lift Doors
Minimum space requirement in depth in relation to the door size
Model insulated door minimizes energy and thermal loss
Depending on design high transparency due to large window slats
High wind load resistance
Door integrated in door leaf.
Folding lift doors are used:
• as interior door to separate rooms and/or climates
• As exterior doors with high protection against burglary
• for large light incidence with aluminium frame sections
The unique guide /folding system works with highly reduced weight on moving parts. Devices to balance the weight of the door slat (adjusting springs) are needless. The result is a long life span and minimum maintenance.
The drives are constructed as shaft-mounted geared motor 400V three-phase alternating current with integrated certified safety catch.The lifting speed amounts to approx. 20 cm/sec.
In the event of a power failure or faults the folding lift door can be moved manually by an emergency crank handle. There is a contact switch on the drive unit in the emergency crank handle inlet to prevent simultaneous electrical operation.
The door complies with the requirements of the workplace regulations, the UVV (German accident prevention regulations) and the harmonised CE directives including the product standard EN 13241-1.
The safety features of the door are designed in accordance with the harmonised CE directives and product standards for power-operated gates. Taking the respective local conditions into consideration additional safety devices and trigger contacts can be required – especially for manual operation. Furthermore, difficult environmental conditions may influence the choice of the appropriate door. In those individual cases we recommend the competent advisory service of our field sales staff.
