At a mining plant in Hungary, SEW-Eurodrive has constructed a huge floating conveyor belt powered by parallel shaft helical and helical-bevel gear units. The plant floats on a lake in Hungary, about two hours from Budapest. It is over 200 meters long and descends to depths of up to 50 meters in the 40,000 square meter lake. The conveyor-plant apparatus transports gravel across eight stages to a nearby plant at a rate of up to 200 tons per hour.
Even though there is no ground beneath the conveyor, it is completely stable and rigid as it floats on pontoons. The bevel-helical gear-driven belts start and stop jerk-free with a 30% excess of power. The whole rig was completed after a very brief six-week construction period. It now supplies construction and filling material from the lake.
