The project was contracted by a loyal customer of Sany, who owned SanySR280、SR285、SR405Considering that the construction of signal tower piles, railway foundation reinforcement piles, rural self-built houses and other pile foundations along the railway requires frequent transfers, short construction periods, and limited site conditions, the customer finally chose to be light and flexible, and can be transported with polesSR165。
