PURPOSE:To enhance work efficiency and safety by fitting the lift arm tip of a wheel type loader with a slewing and telescopic type boom having a water hose and a suction hose along therewith, and providing the tip of the boom with an attachment having water jet and fallen ore suction parts. CONSTITUTION:A quick coupler 9 is coupled to the vertical part (not shown herein) on the mounting bed 35 of a parallel link mechanism 11, and each passage of a wheel type loader 1 is connected to pipe passages at the side of a boom 13. And the loader 1 is shifted to a work position and a lift arm 3 is lowered for locating the mounting bed 35 on the ground and connecting a vacuum hose 73 to a vacuum car. Then, the boom 13 is extended and swung and an attachment 31 at the tip thereof is placed on fallen ores. Thereafter, high pressure water is jetted from a jet nozzle within the attachment 31, thereby collapsing the fallen ores and sucking and discharging the ores via a suction part. According to the afore-said constitution, work efficiency and safety can be enhanced.
