Enstruc supplies robust boom and arm assemblies for excavators working in quarry conditions. Built for high-duty excavation and loading tasks, each quarry excavator boom and arm is engineered to deliver the control, strength, and service life needed in aggressive production environments.
Our front-end assemblies are developed for machines in the 60 to 125 tonne weight class and fabricated from high-strength structural steel. Robotic welding ensures geometric precision, joint integrity, and consistent manufacturing quality. Each assembly is delivered ready to fit, with optional reinforcement and configurations available for demanding quarry applications.
The quarry excavator boom and arm are responsible for an excavator’s lifting and digging motion. In quarry environments, they endure repeated stress during high-force digging and loading cycles, so they must deliver both strength and endurance.
Our standard quarry boom and arm assemblies are made for 60 to 125 tonne excavators, typically used in rock production and bulk material handling.
