Large gantry cranes are the most common lifting and handling equipment used in industry and construction. They are often used for heavy lifting and moving tasks in industrial environments such as ports, construction sites, and manufacturing facilities. Gantry cranes are equipped with a lifting mechanism that can lift and lower heavy objects. The mechanism usually includes a crane or winch system, which may be electric, hydraulic, or powered by other means, depending on the crane design. It is characterized by its tall, rigid steel structure spanning an area, supported by legs or columns on either side.
