Type: ROLLER SCREEN T-ROLL
Roller screen type “T-ROLL” is perfect for projection widths of 10 metres and more. Standard TÜCHLER T-ROLL systems are available up to a projection width of 20 metres. Greater widths are possible depending on the technical conditions of the venue.
System Description:
The top of the roller screen projection surface is integrated into a carrier made of square pipe. This square pipe carrier also contains the motor unit and the mechanism that moves the drive cables and pulleys. The square pipe carrier is attached to the building in at least two locations according to the static requirements. The winding shaft is located at the lower edge of the projection surface and contains a single-layer cable drum on both sides of the outer edges. The drive cables run from the drive mechanism via pulleys from the square pipe carrier to the side of the projection screen to the winding shaft and are rolled up there on the cable drums in the direction opposite to the screen. In the lowest position, the projection surface is unrolled from the shaft with the exception of a few safety windings and the drive cable is completely rolled up on the cable drums. When the drive cables are pulled up, they roll off the cable drum and thereby drive the winding shaft, which causes the projection surface to wind up. The winding shaft “climbs” into the upper end position, carried by the projection surface and drive cables. The construction includes two more safety cables to prevent the winding shaft and cable drums from crashing down should the projection screen be damaged resulting in it tearing off. These wrap parallel to the projection screen and secure the winding shaft against falling in the event of damage. This entire system is designed in accordance with DIN 56950-4 and can therefore be used in event venues.
Intended use for projection in:
- Seminar rooms
- Lecture halls
- Conference + Training facilities
- Universities + Schools
- Multipurpose halls + Event centres
- etc.
in stationary installations. Mobile use in the sense of safekeeping / storage of the equipment at a location other than the immediate place of use upon request.
Technical specifications:
- Maximum standard width of the projection surface: 20 m [greater widths upon request]
- Speed
- Standard 10-20 cm/s
- Optional for standard screens: 60 cm/s as the maximum speed for sections of the travel distance
- Safety
- Standard
- Double brakes with switch monitoring
- Double limit switch [operation/emergency]
- Self-locking gear
- Safety catch
- DIN56950-4
- Optionally upon the request of the client or the authorities
- Electronic overspeed monitoring
- Electronic cable tension monitoring for overload and underload shutdown in terms of increased damage avoidance in the event of a collision
- Electronic positioning of the drive cable for increased repetition accuracy of the end position stops [Please note that the projection surfaces themselves are (thermoplast) plastic and therefore there are construction-related deviations in the repetition of end positions.
- Verifiable statics of the carrying equipment, load information for the suspension points, etc. by agreement
