Second-hand lifting equipment refers to specialized heavy-duty hoisting machinery used in various engineering and industrial applications, including overhead cranes, gantry cranes, traveling cranes, vacuum lifters, and other mainstream models. All units are originally manufactured machines that were previously in service at construction sites, factories, and ports. They undergo professional disassembly and inspection, fault repair, comprehensive maintenance, component replacement, and thorough refurbishment. Following these procedures, the equipment meets all safety standards and can reliably perform vertical lifting, horizontal transportation, and precise positioning tasks for heavy loads. As specialized equipment, this series of second-hand lifting machines complies with operational regulations and delivers stable performance, making it widely applicable in construction, municipal infrastructure, port logistics, mining and energy, steel structure installation, factory equipment reloc
