Hydraulic excavator movable working gear - has protective hoods on shovel arm top end and or cylinder

摘要

The hydraulic excavator (1) has a swivelling arm, boom end bending arm for holding the shovel. They are activated by hydraulic cylinders, with supply pipes leading to them. The top end of the bending arm (4), and/or the hydraulic cylinders (6,7) have covering hoods (9,15) on them. On the arm the hood can be shell-shaped, and bent back to overlap the arm's top end forwards and upwards, and have individually detachable side pieces. On the cylinders it can comprise a U- sectioned piece and an overlapping panel or U-shaped piece. Simple provision is made for reliably protecting working parts from damage.
