In the Jinhai Bridge Project, three sets of QMD750t bridge deck cranes separately developed, constructed, and installed by HL-Kattor were primarily utilized for the building of the Jinhai Bridge. A 3x340m cantilever steel box girder cable-stayed bridge makes up the main span. The box girder has a top width of 49.6 meters, a bottom width of 17.6 meters, and a beam height of 4.676 meters. The primary box uses a single box with three compartments.

Beam trolley series, segment assembly bridge erecting machine, mast crane, bridge deck crane, and other lifting and transportation equipment are among the company's top products. In addition, it offers expert services including synchronous jacking, stepping jacking, and exact three-dimensional adjustment for major bridges. HL-Kattor has consistently concentrated on the research, development, and application of intelligent hydraulic equipment technology in the engineering area as the pioneer of accurate control of large load components
