A few days ago, the TWZ160 submerged double-armed trolley independently developed by Xugong successfully went offline and realized sales. The product fills the gap in domestic construction methods for undercutting methods and becomes another heavyweight member of the underground space construction equipment family.
At present, about 55% of subway construction in China is completed by undercutting construction technology. The technology is mature and the safety performance is good. However, due to the narrow construction space and complicated process, ordinary construction machinery can not meet the construction requirements, so the construction method is undercut. The degree of mechanization is very low. The independently-developed and manufactured TWZ160 concealed arm trolley is a multi-functional operating arm and underground tunnel excavation equipment. It can completely replace all key processes in manual construction of undercutting methods, and has flexible turning and turning. The advantage of extremely small radius is fully applicable to the underground narrow roadway working space.

The first TWZ160 darkened trolley has been sent to Beijing to participate in the construction of the Metro Line 16. TWZ160 has successfully taken off its arms and trolleys and implemented sales to take a solid step for the company to seize the vast underground space construction equipment market.
