Imagine sprinter star Usain Bolt running the marathon distance! One can see very well that this would not be his discipline of excellence. Just like that compromises have to be accepted in terms of life endurance if highest opening speeds are required. The heavy strain may lead to a rise of cost for the change of wearing parts such as torsion springs. The new industrial door SPACELITE HTU-S from Butzbach now offers a solution: it combines perfectly speed and durability, offering an economic operation with low running cost. By combining fast opening with highest economic performance over the entire long life span it offers a reliable, disturbance-free and safe application - even with up to 100 000 opening cycles per year.
Speed is a matter for many door applications to assure a reliable and safe logistic flow. With an opening time of only 4 seconds for a door with a height of 4m the new the Butzbach sectional door grants a maximum protection for the employees and gain of time for the logistics management. The extremely high solidity of the door is at the same time very beneficial against wind load. It guarantees a reliable operation up to wind force 12 (hurricane speed), even with very big door dimensions. So even with strongest wind gusts the door can still be operated to bring the vehicles into safety or to exit vehicles for rescue purposes.
Based on the same technology, the door can also be executed in burglar resistance, with a tested resistance classification of WK3 according to EN 1627.
