1100-TON GIRDER ERECTED IN 8.4M HEIGHT LIMIT

HCR (Heavy Construction Resources) construction team has successfully executed the installation of a 1,100-ton high-speed rail box girder within an 8.4-meter vertical clearance using the DJ1100 Single Box Beam Erector.

Operating at millimeter-level precision, the DJ1100 demonstrated unparalleled structural strength and control stability during the critical lift. The feat marks a new global standard for confined-space heavy lifting in rail infrastructure.
