Installation example // single-format rolling

Installation example // double-format rolling

PATENTED

> Bottom-opening winding system with climbing drive and special-purpose compensating mechanism.

> Compact installation space and easier to assemble. Ideally suited for heavy rolling material.

> No weight applied to roller tube by drive, assuring optimum rolling process and protection of the fabric.

> Reliable and powerful drive system, also in outdoors locations.

> Drive unit can be installed at the end or in the centre of the system, enabling greater lengths, and less torsion on the roller tube.

> With HWA manual drive or EWA power drive. EWA conversionis a simple matter.

> Drives possible with 3-phase or single-phase power supply. > Fully automatic activation with LSR ventilation controller

and wind/rain function. > Patent pending.

Note: > New MPL 75.22 assembly console: to set the inclined angle

to suit the on-site application, to ensure that defl ection angle of universal joints is not exceeded.

> At manual drive without GKT / ATR possible, please use adapter GKA 04.0647.
