Enstruc high reach booms for mining class excavators are built for extreme vertical reach tasks where structural precision and operating safety are critical. Designed for heavy machines in the 100-250 tonne range, these front end assemblies enable high-level dismantling, elevated material removal, and safe remote excavation, whether on mine sites or in industrial demolition environments.
Our high reach booms for mining and quarrying are manufactured from ultra-high-strength structural steel and welded with robotic accuracy to ensure reliability under extreme loading conditions. Each boom and arm system is supplied complete with bucket cylinder, hydraulic lines, pins, and linkage parts, ready to install. Custom options are available for auxiliary tool piping, reinforcements, and attachment configurations, including shears, grapples, and crushers.

They are used for vertical tasks such as highwall removal, elevated bench trimming, or top-down deconstruction of tall mine structures. Their stability and reach make them suitable for precise excavation or dismantling in deep pits or restricted areas.
Yes. Mining-class high reach systems are commonly used in:
Power plant and industrial facility demolition
Deconstruction of tall silos, chimneys, and processing towers
Steel mill and port structure removal
Slope stabilisation and vertical wall shaping in civil infrastructure
Emergency recovery tasks involving unstable structures or debris at height
These applications demand robust reach, safe tool handling, and structural durability.
