Enstruc long reach excavator booms are built to extend the working range of construction excavators for deep trenching, canal and river dredging, slope finishing, and excavation in hard-to-reach areas. Designed for stability, control, and safe digging at extended distances, our front-end assemblies improve operating reach while maintaining smooth, balanced performance.
We supply long reach excavator booms and arms for construction-class excavators up to 55 tonnes, with reach options up to 23+ metres. Each unit is fabricated from high-strength structural steel and welded with robotic precision for strength and accuracy. Long reach kits are delivered as complete, ready-to-install assemblies, including the boom and dipper, bucket cylinder, hydraulic lines, pins, and linkage parts. Auxiliary pipework and attachment-specific brackets can be added as required.

Long reach booms allow excavators to work safely in applications that require extended horizontal or vertical reach, such as deep trenching, dredging and canal clearing, slope shaping, or working from a distance in unstable ground conditions.
Our long reach booms are purpose-built for construction excavators from 12 to 50 tonnes, covering mid-sized to full-sized tracked excavators used in general civil and earthmoving projects.
We offer reach capacities up to 23+ metres, depending on the base machine and attachment configuration.
We supply long reach boom kits compatible with:
Caterpillar: 313–349
Komatsu: PC130–PC490
Hitachi: ZX130–ZX470
Volvo: EC140–EC480
Develon / Doosan, Hyundai, JCB, Case, and others
