Boyoun optimized the design of the form traveler suspension system for safety, given the bridge beam height.It opted to replace the finished rolled rebar with steel slings and increase the calculation of detailed parts of the structure to ensure the safe construction of the form travelers.

Along with the Lannisi Mega Bridge in package 8, the (48+80+48) meter continuous beam of the Dazhuyuan Mega Bridge will soon be completed for closure.To ensure the smooth construction, Boyoun engineers provide comprehensive supervision throughout all stages and facilitate on-site guidance during crucial phases.

Boyoun's professional after-sales service has been consistently recognized by the project department and a letter of praise and a certificate of honor have been sent to recognize their excellent service.

The construction of the north-south extension line of the Weng'an-Machangping railway is a crucial component of the Guizhou Province's railway network and a key project at the provincial and prefectural levels. It is of utmost importance to build and improve the "Seven Expressways, Two Railways, One Port, and One Airport" three-dimensional transportation system of mutual assistance of water, land, and air in Weng'an.
