As with all timing belt products from Transdev, the wide timing belt range can be supplied with over 20 special backings for matching friction and/or antistatic properties. Precision ground finishes and welded profiles can also be included for product positioning and product nests. Vacuum holes and slots for securing components can be machined to suit and pushers and flights can be added to facilitate the customers’ manufacturing process.

For wide timing belt requirements in all other standard metric and imperial pitches, Transdev have also developed an advanced process for longitudinally welding single belts to achieve a double-width option. Through the range, this process allows a 300 mm width for AT20 belts and 150 mm widths for AT5. Timing belt widths can also be customised to suit application requirements.

Transdev also supply the UK’s largest range of matching pulleys for standard and customised timing belt applications and offer cost and quality alternatives from four long-term partners based in the Far East and Eastern Europe as well as providing its own in-house design and manufacture service. Specialist wide pulleys are available for fast delivery using Transdev’s 24-hour manufacturing plant in Poole UK.

Transmission Developments, based in Poole, Dorset are the United Kingdom's premier designer, independent manufacturer and supplier of mechanical power transmission and conveying   products with three divisions covering belting, chain and engineering plastics. The company operate under the Transdev® trading name with exclusive and major partnership distribution agreements with world-class manufacturers and are members of MULCO, the umbrella organization of leading European power transmission companies distributing the Synchroflex®, Breco® and Brecoflex® belt, pulleys and component ranges.

The BRECOFLEX® PU timing belt was the first choice as a power transmission system because it meets the demanding technical specifications for materials used in aircraft construction and features virtually noiseless running, exceptional wear resistance and excellent dimensional stability. Minimal maintenance is extremely important as the lifts in the A380 are totally enclosed within the passenger areas and access is difficult. The nylon tooth facing on the PU timing belt contributes to its extremely quiet running characteristics and high wear resistance.

The complete lift system weighs just 60 kilos with the main aluminium column built in two half-shells supporting the pulleys which run in high grade bearings. The BRECOFLEX® ATK 10 K6 timing belt drives the platform for the trolley and the redundantly designed system includes high-torque electric motor drives with braking and safety devices to prevent the free fall of the heavy trolley in the event of a malfunction. The overall design of the lift system exemplifies space and weight saving techniques for aircraft construction.

The BRECOFLEX® ATK 10 K6 endless timing belt features a central V-guide for guaranteed self- tracking and is part of a full range of BRECOFLEX® POWER, longitudinally extruded polyurethane timing belts with continuous helical tension members with 'S+Z' twist to reduce belt run-off and heavy side loads on flanges. Available in metric pitches of AT5 to AT20 and imperial pitches of XL, L, H and XH, the range features reduced noise, minimal elongation and extremely high wear resistance with belt speeds up to 80m/sec and efficiency to 98%.
