- Title
Model CLG 921ETN Plateau Tunnel Excavator.
- Abstract
Based on the supporting demand for drilling-blasting construction machinery for plateau tunnels, model CLG 921ETN plateau tunnel crawler hydraulic excavator is developed to meet the needs of both internal and external construction of plateau tunnels. The main performance parameters, structural composition and characteristics of the CLG 921ETN plateau tunnel excavator are introduced, and innovative optimization design is carried out for the overall operational efficiency, reliability and safeguarding requirements based on the characteristics of plateau tunnel working conditions. The test results and practical applications show that the excavator can meet the operational requirements of complex environments and harsh working conditions of plateau tunnels.
