Up To 90% Reductions Of Energy And Friction With Latest System Marathon Drag Chains

Typical applications include washing/cleaning stations for railway rolling stock, food industry and horticultural layouts in poly tunnels and greenhouses, together with mobile crane fitments within container handling locations. General industrial applications also occur for milling machines, fast cycling presses, welding machines and steelworks where conditions of high-temperatures and dusty environments apply. Working conditions of variable ambient (5 – 45°C) and high humidity (80 – 100%) can also be accommodated by this highly adaptable equipment.

The system power supply and accompanying cables are terminated at the lower track level, at the horizontal midpoint of the complete installation. The length of drag chain mechanism required is highly economical as it is only 50% of the full installation travel distance, plus a sufficient chain length to cover the curvature of the mechanism occurring in transfers from the upper (running) to the lower (parking) tracks. The full chain length of roller sets provide support on both sides of the chain, eliminating bending or oscillations of the drag chain mechanism, while also ensuring minimum rolling resistance during traverse movements and eliminating chain-on-chain sliding friction. The rollers are running in the smooth sided troughs of the running-track, providing not-only low friction movement but also effectively guiding the chain movement from the upper to lower track running and vice-versa. The minimising of abrasion wear, stress, high flexing and excess loading together with high starting torques are also combined with appreciable reductions in the system operating noises.
