This bachelor thesis deals with the computational and structural design driven horizontal roller conveyor with a length of 100 meters, for transporting plastic material on plastic pallets or in plastic pallets boxes with a maximum load weight 200 kilograms, in the context of internal factory transport. Part of this thesis is functional calculation for the roller conveyor, identifying the main dimensions of the roller conveyor, strength calculations of the casing and the shaft driven roller and implementation of the proposal and check the frame of the conveyor. The appendices contained drawings for the horizontal driven roller conveyor
