Product Introduction
The XE400T tunnel excavator employs technologies such as high-pressure common rail fuel injection and exhaust gas recirculation, meeting China III emission standards. It delivers low-speed high torque, offering robust power and exceptional durability. The cab comes standard with top and front protection devices, while the windshield features laminated double-layer glass, enhancing safety for tunnel construction operators.
Product Advantage
The newly designed working device structure with independent intellectual property rights is equipped with a bidirectional 45-degree rotating working arm, which can meet the construction requirements of arches of different heights;
The low-speed high-torque engine provides sufficient power output, has a good power curve and fuel consumption curve, and is more suitable for the actual working conditions of the excavator;
The efficient and fast hydraulic system is equipped with a new large-diameter multi-way control valve, which expands the valve core control range, improves controllability, reduces channel pressure loss by 30%, and greatly improves the overall composite efficiency of the whole machine.

Product Uses
1. High-Speed Rail and Railway Tunnel Excavation
The XE400T efficiently handles tunnel projects in high-speed rail construction. For instance, during the construction of the Gansu-Ningxia section of the Yinchuan-Xi'an High-Speed Railway, the tunnel encountered Grade IV hard loess soil typical of the Loess Plateau. Previously, conventional excavators were used, resulting in difficulty excavating curved surfaces and low efficiency. After deploying this equipment, construction efficiency increased by 50%, significantly ensuring project progress. Its intelligent tunneling system enables operators to precisely control excavation volume and minimize over-excavation.
2. Subway and Urban Underground Space Development
Benefiting from its compact design and 45° bidirectional rotating boom, the XE400T is also suitable for developing urban underground spaces like subway tunnels. Its working equipment features a tunnel-specific structure, enabling the excavator to better adapt to tunnel cross-sections. Within confined spaces, simply repositioning the machine expands its excavation range.
3. Tunnel Operations in Complex Geological Conditions
The XE400T effortlessly handles challenging tunnel environments characterized by noise, dust, heat, and intense vibrations and impacts. Its optimized intake system design—including intake filters, air filters, and radiators—addresses the issue of oil mist and dust accumulation in tunnels, significantly extending equipment lifespan.
4. Specialized Applications with Multi-Functional Attachments
Through its proprietary intelligent control system for multi-functional attachments, the XE400T rapidly integrates tools like breakers, milling heads, quick-change devices, and specialized tunnel buckets. This achieves multi-functional operation, expanding its application to diverse tasks within tunnels—including breaking, milling, and excavation.
Product Operate Guide
Before operation, inspect the dust filtration system and hydraulic oil level. After startup, idle warm up and activate the tunnel ventilation system. During operation, utilize the intelligent system to control over-excavation, paying attention to the bidirectional operation function for adapting to confined spaces. Regularly clean the air filter element and inspect the reinforced protective devices. Thoroughly clean the equipment after operation, focusing on removing dust from the radiator. Periodically replace the hydraulic oil filter element and lubricate all hinge points. Always keep the cab sealed and closely monitor alarms from the environmental monitoring system.
