A gantry crane is a large mechanical device used for lifting and moving heavy objects in industrial settings. It is characterized by a structure or frame that supports a horizontal beam, known as a gantry, which can be raised and lowered as well as moved horizontally along rails or tracks. The gantry crane is typically equipped with a hoist mechanism, often a hook or grab, which is connected to the gantry and used for lifting and maneuvering loads.
The gantry crane is designed to handle heavy loads that are beyond the capacity of ordinary cranes or human strength. It is commonly used in construction sites, shipyards, warehouses, and other industrial environments where large and heavy materials need to be lifted, transported, and placed in specific locations. The versatility and flexibility of gantry cranes make them useful in various applications, such as loading and unloading cargo from ships, moving containers, assembling large structures, and relocating heavy equipment.
Gantry cranes are available in different types and configurations, including single girder and double girder designs. They can be operated manually or through sophisticated computerized control systems, depending on the specific requirements of a particular operation. Safety features, such as limit switches, overload protection, and emergency stop buttons, are incorporated in gantry cranes to ensure the protection of both workers and goods. Overall, gantry cranes offer a reliable and efficient solution for handling heavy objects, streamlining operations, and improving productivity in a wide range of industries.
The word "gantry" originated from the Old French word "ganter", which meant "to hoist" or "to lift". The term later evolved to "gantier", which referred to a person who made and operated hoisting devices. Over time, "gantry" came to represent a framework or structure used to support and lift objects.
The word "crane" is derived from the Old English word "cran", which denoted the long-necked bird. This term was used metaphorically to describe a machine or device with a long arm or neck, resembling the bird's body shape. Thus, a "crane" started referring to a mechanical lifting machine with a projecting arm or jib.
Combining the two terms, "gantry crane" retains the historical reference to a hoisting mechanism (gantry) while incorporating the idea of a machine with an extended arm used for lifting (crane).
