NEWXCMG TWZ180D Subsurface Excavation Bogie
Made TWZ260 Subsurface Excavation Bogie come into being. The bogie adopts platform, modular and standard design,
Maximally considers interchangeability of parts, and innovatively applies multiple cutting-edge technologies. It is the pioneer both at home and abroad.
TWZ Series Subsurface Excavation Bogies is the specialized equipment designed for the subsurface excavation construction of the city tunnel project. The products are suitable for the stratum construction, including mollisol, sand-cobbie, decomposed rock, etc. It has many functions such as earth excavation, slotting, hitting ductule, breaking rocks, auxiliary shoring and deslag. The equipment adopts external power source, hydraulic drive and track chassis walking. The products are highly effective and environmental friendly. They have compact structures with great flexibility, and can effectively take the place of manual operation, greatly improving the working efficiency, which responds to the requirements of “replacing manpower by mechanization, and reducing manpower by automation” by the State Administration of Work Safety.

As the original products of XCMG with its completely independent intellectual property rights, XCMG TWZ Series Subsurface Excavation Bogies have been successfully applied in many metro and civil projects including in Beijing and Xian since available.
They are regarded as the magical artifacts in the metro subsurface excavation construction. They offer significant economic and social benefits with its environmental protection, high efficiency, safety and reliability, gaining wide recognition and praise by government departments, proprietors and construction organizations.

As a special equipment developed for underground excavation of subway tunnel projects, this product is suitable for the operations under soft soil, sandy gravel, and decomposed rock stratums.
It incorporates the earthwork excavation, trenching, small duct drilling, rock crushing, auxiliary support, and deslagging functions.
Its mainly suitable for the excavation of pilot tunnels and stations in size of 4mx4m. This equipment is equipped with external power supply, hydraulic drive, and crawler chassis traveling system.
Featuring high efficiency and environmental-friendliness, compact structure, and high mobility and flexibility, this product can effectively substitute the manual operations and remarkably improve the working efficiency.

The right arm is mostly applied for the formation of advanced ductile and the milling of top slot. The arm applies two sets of inverted-triangle suspension support, which can achieve the precise full-section parallel maintenance function with a steady motor process. It has improved the positional accuracy of the work and has implemented the ductule hitting across the obstacle.

By applying the variable control system, the bogie saves energy and has high efficiency. It provides reliable quality with all the key components imported from famous brands.

The bogie produces no exhaust gas for its electrical drive. It adopts low noise design which would decrease the noise pollution.

Working with the bogie can greatly decrease the labor intensity of the workers, reduce the amount of staff and improve the working efficiency. The number of working staff can be reduced by 4 per shift, while the working efficiency doubles. An amount of 8 million yuan per kilometer can be saved in the management fees, and 3 million yuan in the labor cost.
