Overcoming difficult construction techniques and setting new records for multi-scenario hoisting
2025-12-29In China Coal's Beijing Huating Center Washing Plant Project, the construction team innovatively overcame the problem of hoisting ultra-high and ultra-large-span steel trusses. For complex scenarios spanning rivers, highways and 8-strand railways, 450-ton and 650-ton crawler cranes are used to implement single-machine lifting + 90-degree spatial rotation technology to avoid river support erection and high-voltage line disconnection; in 7 During the hoisting of the 9-meter ultra-large-span steel truss, the "dual main crane + auxiliary crane" collaborative plan was pioneered, using 800-ton and 650-ton crawler cranes as the main cranes, and a 260-ton truck crane in cooperation, successfully placing the 280-ton load accurately in place. In response to the dilemma of "blind lifting" at high altitudes, visual hook monitoring and drone detection technology are integrated to solve the problem of obstructed sight caused by the obstruction of raw coal bunkers.
