Description

Technical Field

[0001] This utility model relates to the technical field of gantry cranes, and in particular to a mobile gantry crane. Background Technology

[0002] Gantry cranes are a new type of small-scale lifting gantry crane developed to meet the daily production needs of small and medium-sized factories (companies) for equipment handling, warehouse loading and unloading, lifting and repairing heavy equipment, and transporting materials. They are suitable for mold manufacturing, auto repair shops, mines, civil construction sites, and other applications requiring lifting capabilities. Commonly used in construction, they serve as both material transport and personnel access points, achieving mechanized lifting. This reduces manpower, lowers production and operating costs, and improves work efficiency.
