Ironwork

Ironworks are tailor-made to specific dimensions compliant with the most relevant technical standards.

Available ironwork for industrial doors:

• Standard lift
• Low headroom (springs in front)
• Low headroom (springs in rear)
• High lift
• Following the roof lift
• Vertical lift             

It is necessary to have the exact measures (openeing width and height, lintel, side area) for determining the right type of ironwork. 

	Standard lift – is the most frequently used ironwork made for lintel with minimum height of 400mm. Advanteges of standard lift: - the clear passage height is equal to the opening height - both ceiling operators and industrial opretaors can be mounted
	Low headroom (springs in front) - height of lintel should be minimum 330mm (for height only 300mm we recommend that top seal be fastened to the lintel). With this ironwork both ceiling operators (door range max. 15m2) and industrial operators can be mounted.
	Low headroom (springs in rear) - height of lintel should be minimum 230mm. Difference to the previous ironworks is that the prings are fastened not to the lintel but to the end of the horizontal track. The clear passage height is approximately 50-70mm lower than the opening height. This type of ironwork appears rarely in industrial section. Both ceiling operators (door range max. 15m2) and industrial operators can be mounted.
	High lift – is mainly used for higher headroom, if bigger usable space required under the horizontal tracks (for example in autoservice-station). Advantage of this ironwork is that it reaches to the ceiling nevertheless it is too high. Take care that only industrial operators can be mounted and on one side minimum 250mm area is needed
	Vertical lift – mainly used for big halls, where the height of lintel is minimum opening height + 500mm. The ironwork consists only vertical tracks, which are parallel to the lintel (with light slope). Take care that only industrial operators can be mounted and on one side minimum 250mm area is needed
	Following the roof lift – this ironwork is designed for garages without a ceiling. The tracks are following the roof in an angle. Take care that only industrial operators can be mounted and on one side minimum 250mm area is needed
