PURPOSE:To permit the supplying operation of piles to several pile drivers to be performed by only one auxiliary crane by a method in which piles are hung up and supplied to a pile driver by using an auxiliary crane and the hanging of the pile is released by remote-control operations. CONSTITUTION:A winder 8 coupled to a remote controllable hanging holder A attached to an auxiliary crane 10 is wound around a pile 16, hung up, and supplied to a pile driver 13. A stopper plate 4 is removed by remote-control operation and a set pin 3 is pulled to release the winder 8 from its operation. The number of auxiliary cranes to be used in the work can thus be reduced and the cost of operation and labor can also be saved.
