1 Industry Heavy Duty Lift Doors for Trade and Industry

2 For Optimum Availability of Lifts in Trade and Industry: Heavy-duty MEILLER Lift Doors. Large capacity lifts for heavy and bulky loads must fulfill extreme requirements with regard to strength and availability. That applies especially to lift doors the components that experience the most stress in a lift. When passenger lifts are down, there are still stairs available, but when a freight lift is out, the entire production stops. And that costs a lot of money. Michael Mattheis Daimler AG, Mercedes-Benz 2 In large production facilities, such as in the automotive industry, freight lifts are often a functional part of a production line or a logistics system. These lifts are operating nonstop. Problems arising from a lift integrated into such a system, and possibly caused by defective doors, could block the entire production. In turn, such downtimes result immediately in immense costs for the operator. That s why the performance and reliability of a lift as well as low maintenance is a top priority. MEILLER s range of solid and strong sliding and swing doors will exceed this demand.

That applies especially to lift doors the components that experience the most stress in a lift.

3 MEILLER Quality in Detail Industrial lift doors from MEILLER combine all standard quality characteristics of highquality doors, supplemented by special peripheral equipment for heavy industrial doors: Door transom Closed box-section with side walls, sheet thickness min. 2.5 mm, resistant to deflection and dirt. Guide rails Very rigid, made of steel with high section modulus for great stability and smooth operating characteristics. Track rollers Mated to the contour of the guide rails, diameter generally 65 mm, ball bearing and made of high quality polyoxymethylene (POM) for best operating characteristics, optional heavy-duty rollers made of cast polyamide to withstand extreme stress for long service life. Strong, safe door shoes continuously variable, can be replaced when needed without disassembling the door panels. No complex, cost-intensive replacement of the entire door panel in case of damage in the sill area. This means greater operational reliability and minimum downtime. Continuous sill support for landing doors (option) for lifts with high rated load, allows fast installation, simple alignment and prevents a concentric height offset. Strong steel sill edge, generally made of profiled tubing or solid profile section. THERMOLIT door panel variation especially for off-site facilities for high dimensional stability in case of direct solar irradiance. Heavy, robust door design ensures stability and high performance operating characteristics. All of these product characteristics of MEILLER lift doors mean Reduced maintenance time Reduction of problems Long service life Low operating costs. 3

4 MEILLER s Peripheral Equipment Specifically for Heavy Industrial Doors. Comfort skate Constant positive fit and force closure between car and landing door during the entire opening and closing process until the end position is completely reached by the expanding skate kinematics. Both followers move relatively away from each other when the doors open and towards one another when closing. Skate made of galvanized steel, low maintenance, highly resilient, equipped with a pivoting mechanism running on a needle bearing. No problems in the lift due to incompletely closed landing doors. Patented zone locking The patented zone locking EP , type-tested by TÜV in accordance with EN 81/Part Failure-free operation thanks to mechanical functional principle. Reinforced kicking rollers Kicking rollers on the leading door panel, made of steel with flange increase stability and safety against falling. Reinforced continuous bottom guide shoes Door panels with reinforced continuous guide shoes for increased stability and safety against falling. Optional versions Protection classes for water-proof and explosion-proof design. 4

5 Telescopic Sliding Door ZENIT MEILLER s 6-panel heavy load door of special dimension Clear opening: DW 2500 to 5000 mm x DH 2500 to 5000 mm. Transom as welded box-section made of 5 mm sheet steel. Door hangers with oil-resistant track rollers, running on ball bearings, Ø 120 mm and kicking rollers Ø 65 mm. Door panels made of galvanized 2 mm sheet, double-skin with internal reinforcing ribs. Continuously variable door guide shoes, solid steel sill with dirt trap, replaceable from above when door panels are opened. Both door halves are driven synchronously via a twin skate system. Skate system with forward control and backlash-free connection between landing and car doors during the entire opening and closing cycle. Quickly replaceable skirting protection made of rectangular profiled tubing 50 x 80 x 4 mm, mounted in front of the slam posts recessed accordingly. When the door is open, the door panels are 50 mm behind the skirting protection on both sides. Consequently the door panels and slam posts are protected against damage. Solid steel sill for maximum rated loads, can be replaced with door open without having to disassemble the door panels. Significantly chamfered sill profiles to prevent flash formation. VF door drive MAT-1600, protection rating IP 54. Simple to adjust using potentiometers. The low maintenance door drive is synchronized on two toothed belts (20 mm wide) and controlled by a microprocessor. Clear mechanical layout of individual components. No limit switches required, freely selectable running characteristics. Optional twin skate TA 8 DV with patented zone locking system.

6 Variations of Heavy-duty MEILLER Industrial Doors MEILLER sliding doors in series 21, 22, 28, 31 and 32 of industrial design are available depending on model and version with a door width from 700 to 3500 mm and height from 2000 to 3500 mm. Heavy load doors of the special ZENIT dimension are manufactured starting with a door width / height from 2500 to 5000 mm. Depending on model series, version and dimensions, MEILLER industrial doors satisfy diverse, country-specific requirements, e.g. DIN 18091, EN 81-58, BS 476 and NEN Special sizes based on customer specifications are possible on requests. 6 During a serious fire in a production building in Southern Germany, MEILLER doors (in this case the six-panel landing door TTS 22) proved to be an excellent bulk head against the fire. The shaft was almost the only part of the building to survive the inferno without damage.
