Abstract

PURPOSE: To raise the working efficiency by providing a freely expansible leader by which a working device, e.g., hammer, auger, etc., is elevated.
CONSTITUTION: Leader cylinders 1 and 1' are extended by an oil-pressure cylinder 5 and a working device 10, e.g., auger, etc., is mounted to the guide pipe 2 of the outermost leader cylinder 1. When said working device 10 is lifted by a wire, etc., an excavator 11 is transferred from the guide pipe 2 to the guide pipe 2' of an auxiliary elevator B, and when the device 10 is further lifred, the excavator 11 is coupled by a stopper 3 and accompanied by the auxiliary elevator B. When it is furthermore lifted, the auxiliry elevator B is transferred to the carrier C of the leader cylinder 1" and accompanied by the auxiliary elevator B and the carrier C by a coupler 4, the working device 10 is lifted along the leader cylinder 1".
