MEILLER CAT2® vandal-proof doors comply with EN 81-71, category 1 and 2 and are generally supplied with ScooterGuard® function without any extra charge.
MEILLER CAT2® vandal-proof doors are available in two versions:
| Type | Door version | Door width | Door height | ||
|---|---|---|---|---|---|
| TTS/TTK 25 | S/K 2 R/L | side-opening | 2-panel | 700 - 1400 mm | 2000 - 2200 mm |
| STS/STK 26 | S/K 2 Z | centre-opening | 2-panel | 700 - 1400 mm | 2000 - 2300 mm |
| TTS/TTK 28 | S/K 4 Z | centre-opening | 4-panel | 1300 - 1800 mm | 2000 - 2300 mm |
Intermediate sizes and other dimensions available on request.
Further information about range of dimensions.
The width of the groove for the bottom guide shoes is only 7 mm or can be completely closed (hidden track). Large smooth contact surface for the slide components of the bottom guide shoes.
The doors are generally equipped with a 3 mm thick transom with side plates of sheet steel with zinc magnesium coating. As a result, the transom is very resistant to torsion, allowing it to connect to the landing wall over the entire width of the door.
Long service life - use of wear resistant steel. High rigidity through optimised component geometry with great section modulus in the running direction and at 90°. High-quality running surface due to special precision manufacturing process. Low movement noise thanks to the low surface pressure between tracking rail and track roller. Subsequent replacement possible (tracking rail as separate component).
Low-maintenance, variable speed DC drives integrated into the transom. Easily adjustable travel curves. No independent door movements without a command from the lift control system. Automatic door width determination. No limit switches necessary, since DOOR Open and DOOR Closed positions are automatically recognised. 7-segment display in controller.
For long service life, strength and safety: Low-wear mounting of moving parts, e.g.with rolling or sliding bearings. Optimum force transmission between the locking elements hook lock and latch (no leverage moment). For centre-opening doors, locking is generally not implemented by means of the guide cable, but rather the hook lock,
latch and latch retainer.
Double-skin reinforced door panels 1.5 mm with increased stiffening. Reinforced bottom guide shoes with variable adjustment.
All components are easily accessible and can be replaced quickly and easily.
For long service life and high strength: Use of high-quality materials. Easy replaceable wear parts (track rollers/kicking rollers). Sturdy component geometry as continuous plate with stiffening and reinforcing especially on the fast door panel. For optimum positive locking to the tracking rail: two track rollers and kicking rollers per hanger, fitted without play to the tracking rail. Reinforced collared kicking rollers made of steel on fast door panel. Door panels connected to the door hangers by means of reinforced eyebolts for optimum positive locking and infinite adjustability without pins.
Sheet thickness at least 2.0 mm. Closing weights inside the door frame for constant and controlled closing force.
Long service life thanks to use of: Low-maintenance roller bearings. High-performance plastics, e.g. cast polyamides. Minimum flattening characteristics. Accurate matching between track rollers and geometry of tracking rail results in low movement noise and long service life.
Complete closing of landing door and controlled locking of hook lock (no residual movement by closing spring or weight), since both skate brackets carry out a relative movement in relation to one another after the car door closes. Support of the moving levers and skate brackets by means of high-quality roller bearings (e.g. double deep groove ball bearings or needle bearings). High-quality materials for skate bracket and lever mechanisms (galvanised steel, no aluminium injection moulding or plastic). Skate with mechanical car door locking mechanism.
