Enstruc high reach excavator booms are engineered for quarrying class excavators working in vertical or elevated applications such as bench wall scaling, high-face material removal, or precision top-down demolition. These long vertical reach systems provide safe, controlled operation at height while maintaining structural integrity under extreme stress and heavy tooling.
Our high reach boom and arm assemblies are built for excavators in the 60 to 125 tonne class. Each unit is constructed using high-strength structural steel and robotic welding to ensure dimensional accuracy and performance in demanding conditions. Supplied as a complete kit, each high reach system includes the main boom, middle arm, front arm, bucket cylinder, linkage, pins, and hydraulic lines. We also offer reinforced options, auxiliary piping, and configurations for hydraulic attachments such as shears, breakers, or grapples.
