HY265TM Tunnel Machine

Hiyo HY265TM-S is a 26-ton tunnel-specialized excavator independently developed by Hiyo Heavy Machinery. Inheriting the high power and energy-saving advantages of SY265H, it targets tunnel construction pain points including slow attachment replacement, insufficient rock-breaking power, rock damage and heavy dust. Equipped with one-click quick coupler system, it realizes instant attachment switching for multi-scenario seamless operation. It adopts reinforced working structures, full protective cab and intelligent control system, delivering strong breakout force, stable operation and safe driving, perfectly matching railway tunnels, mine slope repair, earth-rock excavation and municipal reconstruction.

Key Highlight Features

1. Cummins B7 engine with 150kW rated power, DOC+DPF+SCR stage IV emission tech, full combustion and low fuel consumption.
2. Custom Kawasaki full electronic positive flow hydraulic system, energy recovery tech, fast cylinder response and powerful tunnel hazard removal.
3. Quick coupler pipeline for instant attachment swap, reinforced torsion-resistant boom & arm plus standard rock bucket.
4. FOPS/ROPS fully protective cab with sound insulation, long lower frame, thick track shoes and special counterweight for anti-tip stability.
5. Upgraded 10-inch intelligent touch screen, one-hand pattern switch, delayed lamp shutdown, rear camera and one-call service function.

Performance Advantages

1. Powerful & Efficient: High-torque Cummins engine and upgraded RG16 slewing device lift rotary capacity; hydraulic response speed boosts loading & rock-breaking efficiency greatly.
2. Durable & Anti-wear: Thickened structural plates and reinforced bucket hinge reduce digging resistance by 10%, resisting rock impact in harsh tunnel conditions.
3. Flexible & Multi-purpose: One-click quick change cuts attachment replacement time, switching between excavation, trimming and mucking without delay.
4. Stable & Safe: Widened lower frame and heavy counterweight improve anti-overturn capacity; full protective cab avoids rock impact injury.
5. Low Consumption & Smart Control: Precise fuel injection control cuts fuel cost; intelligent screen simplifies operation with multiple working modes.
