General 2.1 Application 2 PLATES better head treatment greater tensile strength PINS Solid pin, hardened and tempered for better cord strength BUSH Sintered or solid shouldered no plate 2.2 Design of Chain The evolution in materials, heat treatment, manufacturing process had given the opportunity for us to innovate and produced conveyor chains for palm oil mill applications. These chains adapted to basic gearing dimensions but with greater breaking strength providing a higher service factor and reliablity. From carry palm fruits from elevator to the incinerator or in conveying fruits, fibres, kernel nuts on a horizontal or incline conveyors, our LUGER chain are built to performance in this tough environment. In ensuring the quality of chain, the control begin with the inspection of the raw material, better heat treatment, stringent tolerances, precision heavy pressing fit and riveting and finally high accuracy in assemblying. All these are key to produce a high quality chain so that it will reduced the rate of chain premature failure and improved the life expectation. LUGER â Megadrive Megadrive 2.
