Product Introduction

Hengwei Machine excavator tunnel boom is specially designed for low‑clearance work in underground tunnels and subway projects.

Custom sizes for different tunnel heights are available, compatible with Caterpillar, Komatsu, Hitachi, Volvo, SANY, XCMG and other mainstream excavators. Complete attachments enable quick installation. Strict inspection before shipment. Widely used in tunnel and utility tunnel projects worldwide, with professional technical and after‑sales support.
