The massive steel-framed sliding doors slide easily with high-quality sliding track systems
Cramo built the one of the largest logistics center in the European rental industry in Vantaa, Finland. The total area is about 24,000 m2, of which the logistics, workshop and warehouse facilities are about 21,000 m2 and the office building about 3,000 m2. Five large outdoor storage halls with a total length of more than 400 meters were built in the logistics center. The halls had to have doors that are easy to use, protect the equipment inside and that can be closed if necessary, making sliding doors the best solution for this project. There were a total of 80 heavy sliding doors in the halls. The size of one sliding door was 5000 x 5750 mm and the weight of one door was about 400 kg. Big sliding doors require durable sliding track systems, which is why Helaform stepped into the picture.
The weight of the sliding doors determined the track system that the doors ended up being used for. The 500 Series has a load capacity of up to 500 kg, so for these 400 kg doors it was ideal choice. Two track lines came side by side (940 meters of track). The MPS-300/500 / steel was used as the hanger in this project, because as in this case the hanger bolts were pre-installed in the doors through the frame and since the MPS hanger has “hooks” ready, the door could only be lifted and tightened into its place. With such large doors, proper bottom guiding is important. AO-22 bottom guides were attached to the support beams between the openings, which slides inside the bottom guide tracks attached to the doors. Because the sliding doors themselves were quite thick and there was a desire to leave more gaps between the sliding doors than usual, Helaform made the extra-long L-bottom guide plates. This brought the bottom guides out of the support beams enough and ensured smooth operation.
