Abstract
A lengthy article transferring apparatus transfers lengthy articles between the apparatus and target locations for the transfer. A lifting driving device lifts and drives a platform and a transferring device mounted thereon by winding a cord-like member. A controller controls actuation of the lifting driving device and the transferring device. A lifted position detector monitors the position of the platform. The controller performs the transferring operation to actuate the transferring device when end portions of the platform are received and supported by receivers provided at the target locations for the transfer, and performs a lifted position adjustment procedure controlling actuation of the lifting driving device based upon information detected by the lifted position detector during the transferring procedure to absorb variation in the position of the platform caused by a shift in the load acting on the platform as the article is transported in the article transferring direction.
