Kelude Heavy Industry's gantry cranes—also known as gantry crane systems or portal cranes—cover a full product line with lifting capacities from 1t to 320t and spans ranging from 5m to 50m. A gantry crane is a type of lifting equipment in which the bridge structure is supported on ground-level crane rails by outriggers on both sides, allowing it to travel along the rails. It is primarily used in open-air storage yards, freight yards, and workshops. The product line includes the MH type single-girder gantry crane, MG type double-girder gantry crane, MHE type European Standard (EN) gantry crane, L-type offset-mounted gantry crane, and rubber-tyred gantry crane (RTG), among others, to accommodate various operating conditions and budget requirements for material handling. The main girder is a box-section structure welded from Q355B high-strength steel plates, with all weld seams undergoing 100% ultrasonic testing (UT) for flaw detection, ensuring structural integrity. These cranes are widely used for material handling in steel smelting, port terminals, logistics and warehousing, and precast component yards. Kelude Heavy Industry provides a one-stop solution from selection and design through installation acceptance.
