Relying on industry-leading R&D strength and innovation capabilities, Huayuan crane has developed a 2000t rail-mounted gantry crane for the complex working conditions of the project, with a total lifting height of 90m and a span of 62m. The AWS standard is adopted in the manufacturing process, which can guarantee the safety of hoisting heavy objects to the ground in extreme cases, realize zero-speed braking of each mechanism, reduce the load caused by impact to zero, ensure the stability of the operating mechanism and lifting mechanism, and meet the requirements of Equipment installation accuracy requirements.
