PURPOSE: To efficiently run a gondola and shorten its moving time, by attaching a preceding brush to a synchronizing member to automatically determine an appropriate reference maximum speed pattern for short run despite the difference in the height between floors.

CONSTITUTION: The preceding brush 17 is attached to the synchronizing member 19 of a floor selector so that the brush is located at a prescribed distance So ahead of the synchronizing member. When a starting instruction SI applied to the gondola, an initial value Co corresponding to the distance So is entered into a counter 11. When the gondola is moving, the output of a pulse generator PG is added to the initial value Co in the counter. The output of the counter 11 is applied to an amplifier 13 through a D-A converter 12. The output of the amplifier 13 is supplied to a sample hold circuit 15 through a route generator 14. When the brush 17 has come into contact with a floor member 18, the output of the route generator 14 is held. If the output of the generator 14 is not higher than a prescirbed value, the output is supplied as a reference speed pattern from a limit circuit 16.
