Roller conveyors from the MiniTec modular system are available for higher loads. The user now has a range of perfected, suitable solutions as belt or roller conveyors to choose from for all piece-weights from 0.5 kg to 300 kg. The chain-driven roller conveyor RFK 300 is designed for loads up to 300 kilograms. The modular design principle enables both one-sided and two-sided chain drive. The special carrier profiles have the same grooves as the MiniTec standard profiles, so that all system components can also be used for the roller conveyors. The rollers are mounted in the carrier profile, at the same time it acts as a guide track and cover for chains and sprockets.
