HL-Kattor specially customized a 2200t Modular Spreader Beam for the Aotai project, HL-Kattor took into account all of the unique topographical, hydrological, and construction requirements of the project site. At the same time, the team has discovered a matching installation of various steel beam types that has powerful features like a heavy load and multi-lifting point, self-balancing, automated switching, and incredibly easy control after conducting several tests in the company's production base.

The maximum length of a single girder spreader is 80m, the maximum weight is nearly 2000 tons, and the total weight of the steel girder hoisting is more than 100000 tons. This is the first time that HL-Kattor 2200-ton Modular Spreader beam has carried out high-load operations like this. The heavy load of the slings reaches 86.9% of the rated load.
