Robust multi-tool assembly for hydraulic excavators

A hydraulic excavator tool adapted to be secured to an excavator boom comprising:

• (a) a main tool assembly including:
• i. a main tool framework, and,
• ii. a spaced apart pair of connection flanges fast with said main tool framework, and,
• iii. a structural tubular casing integral with the main tool framework extending across and through the main tool framework and through the flanges, and
• (b) a rotary hydraulic actuator within the tubular casing extending between the connection flanges and adapted to provide a rotational drive motion of a drive axle,
• (c) the drive axle extending between the connection flanges adapted to provide a rotary drive motion of the axle adjacent the connection flanges,
• (d) a working tool framework being fast to the drive axle adjacent each of the connection flanges for rotation of the working tool framework about the drive axle between the main tool framework and a working position, the working tool framework being fast to the drive axle by a pair of working arms, the pair of working arms being spaced apart at the drive axle by a distance that is greater than a width of the main tool framework at the drive axle and less than a maximum width of the main tool framework.
