Enstruc long reach booms are built for excavators operating in quarry environments where extended digging distance and depth are critical. These assemblies are made for slope trimming, bench excavation, drainage management, and material handling in deep or inaccessible quarry areas, providing increased reach without compromising on strength or machine balance.
Our long reach excavator booms for quarrying are designed for machines in the 60 to 125 tonne class. Each set is engineered using high-strength structural steel and welded with robotic precision to ensure alignment, durability, and reliable long-term performance. Boom kits are delivered ready for installation, complete with bucket cylinder, hydraulic lines, linkage parts, and pins. Custom options are available for attachment compatibility, additional reach, and application-specific reinforcements.

Long reach excavator booms in quarrying are used where standard booms can’t reach safely or effectively. Typical tasks include slope maintenance, deep bench excavation, trenching, and reaching across stockpiles or unstable ground.
Our quarry long reach kits can offer horizontal reach capabilities of up to 30+ metres, depending on the base machine and configuration.
We supply long reach boom and arm assemblies for:
Caterpillar: 374, 390, 395
Komatsu: PC600, PC700, PC1250
Hitachi: ZX670, ZX690, ZX890
Volvo: EC750, EC950
Liebherr: R 956, R 966, R 970
Hyundai: HX800, HX900
Develon / Doosan: DX800LC, DX1000LC
