An Experience Report on Systems Development and Design Using a Rapid, Non-Formal and By-Customer-Demand Approach

A carrier car, for conveyance by a carrier car conveying chain, may be stopped at a desired position at a work station or in a storage section and re-started from the stopped position. A carrier car conveying chain 3 is disposed in an endlessly entrained fashion on one side of the work station or storage section. Shoe members 2 attached to the underside of the carrier car are supported on conveying rollers 4A and 4B of the conveying chain 3. A traveling track is disposed on the opposite side of the work station or storage section and traveling wheels of the carrier car are supported for rolling movement on the traveling track. The rotational friction force of the conveying rollers is made larger than the rolling friction force of the traveling wheels.
