Abstract

PURPOSE:To aim at the simplification of structure by driving a lift equipped with a fork arm with a lifting rod installed in a diagonal end, and also driving a carriage traversing on a rail by a motor installed in a column via a chain. CONSTITUTION:A lift 1 consisting of a pair of supporting levers 7 equipped with a fork arm 6 each is synchronously driven up and down by a motor 24 via lifting rod 13 attached to a guide rail 8 at a diagonal end. In addition, a traverse carriage 11 equipped with th fork arm 9 is driven by a motor 31 via a chain 34. Then a car is mounted on the lift 1 from a drive-in port, while the carriage 11 is carried in a lower side of the lift 1 and, after the lift is lowered and the car is transferred onto the carriage, it is conveyed to the specified storage place. When the car is ungaraged, it is conveyed up to a lift hoistway 2 by the carriage 11, and then the lift 1 is made to go up and the car is transferred onto it and thus it is ungaraged. With this constitution, a system is simplified and simultaneously its conveyance is accurately performable.
