22ton Excavator Short Boom Arm Hammer Subway and Tunnel Arm for ZX PC CAT

Introduction of Excavator Short Boom Arm

Tunnel construction presents challenging conditions with confined workspaces, making standard excavator arms ineffective due to their inability to rotate. While compact excavators are often used as an alternative, their efficiency is limited. To address these constraints, we have developed a next-generation shortened arm specifically engineered for tunnel operations. This innovative design features a reduced length and enhanced maneuverability, allowing smooth rotation even in tight spaces—significantly improving productivity in demanding underground environments.
