Loading work apparatus with attachment tools

摘要

A loading work apparatus includes booms, attachment tools, an implement tool removably attached to the attachment tools, and implement tool cylinders. The implement tool includes an engaged member on a back surface thereof. The attachment tools include an attachment unit having an engaging member engaged with the engaged member, coupling members supporting the transverse shaft, and lock members locking/unlocking engagement between the engaging member and engaged member. Each coupling member includes brackets on lateral opposite sides of the lock member. The transverse shaft is supported at opposite ends thereof by lower portions of the right and left brackets. The support shaft is supported at opposite ends thereof by intermediate portions of the right and left brackets. The transverse shaft and the support shaft bridge across the lock member.
