Abstract

PURPOSE: To facilitate the change of a clamshell and an arm with a backhoe backet by mounting an auxiliary guide sheave for operating an operating rope with two sheave supporting frames removably mounted on the boom and a base body.
CONSTITUTION: After a clamshell backet 30 is lowered down on the ground, a mount pin 84 is pulled out and the second supporting frame 83 is separated from a base body. When a boom 11 is tilted down to reduce an arm 14, a space increases between the front end of the arm 14 and the backet 30 and the second supporting frame 83 get into contact with the first supporting frame 89. A hydraulic cylinder 20 is driven to close the backet 30 by winding an operating rope 99. Then, the operating rope 99 is pulled to hoist the first supporting frame 89 and the second supporting frame 83. A mount pin 90 of the first supporting frame is removed and the first supporting frame 89 is separated from the boom 11. The first supporting frame 89 and the second supporting frame 83 are lowered and the operating rope 99 is removed from an operating rope auxiliary sheave 24. An arm with a clamshell backet is removed from the boom 11. An arm with a backhoe backet is mounted on the boom 11.
