Product Feature
Subsurface excavation bogie is developed for subway tunnel engineering construction, and is applicable for the construction in soft soil and cobblestone stratums. It has the functions, such as earthwork excavation, excavation waste discharge, grooving, conduit digging, auxiliary support and auxiliary wet spray. It is designed with the external power supply, and is hydraulically driven crawler chassis walking and double-arm working equipment. It is characterized by high efficiency, environment-friendliness, compact structure and good manoeuvrability. It is free from the influence of tunnel section shape, and can replace the manual work in large area.
