Standard lift

Standard lift is the most common system of door rails. It is applicable when free room above lintel is between 420 mm and 1000 mm. Tension springs are placed above vertical part of rails. Horizontal tracks can be produced as "following the roof".

High lift

When free room above lintel is more than 1000 mm, High lift system is better solution than Standard lift but can be installed also for lower lintels. This system economizes free room above lintel as much as possible - door tracks rise upwards and they arch close to ceiling. The result is that higher space behind door can be used for your activity. The height of HL is the measurement, as of the bottom side of the lintel up to the bottom side of the horizontal door tracks. Standardly are tension springs placed above vertical part of rails but can be also placed on sleeve above opening. Horizontal tracks of high lift system with springs above vertical part of rails can be produced as "following the roof".

Vertical lift

When free room above lintel equals the height of opening + 400 mm, door without horizontal part of rails can be installed. Such doors have only vertical part of rails and this is the reason why we call them Vertical lift. Tension springs are place above rails but can be also place on sleeve above opening.

Low lift

Low lift is special system of door tracks which can be applied from lintel heights 200 mm. However for such low lintel the tension springs must be installed rear (behind horizontal part of rails). When tension springs should be installed front at lintel, minimum space of 330 mm above opening is required. There can occur situation that cables of door are not running inside of door track (as it is for other lift types) but they run outside. Characteristic feature of low lift system are double horizontal rails which ensure better sealing of the door blade (top section).
