A heavy-duty gantry crane is a type of crane that utilizes an overhead gantry beam and uprights to support a hoist and move heavy loads horizontally and vertically. Heavy-duty gantry cranes are designed to handle high weight capacities and are commonly used in construction, manufacturing, and shipping industries, as well as in ports and harbors. They may be fixed or mobile and can be customized to meet specific application requirements. Heavy-duty gantry cranes are typically made of high-strength steel and feature robust components and controls to ensure safe and efficient operation.
