Our 9m Long Reach Boom & Arm for Hitachi ZX75 Excavator is fabricated from high-strength low-alloy steel plate. It undergoes stress relief treatment post-welding to resist deformation even during prolonged heavy-duty work.
Hydraulic pipes are pre-routed and secured neatly, cutting down your on-site installation time significantly.
Pre-built breaker hammer oil lines are reserved. No extra pipe modification will be required if you fit a hydraulic breaker later.
Pin holes are precision-machined for perfect alignment with the original machine mounting points. Excellent coaxiality keeps wear to a minimum.
