Goliath cranes, also known as gantry cranes or portal cranes, are large, heavy-duty industrial cranes designed to handle heavy loads and operate in outdoor environments such as construction sites, shipyards, and container terminals. These cranes are known for their massive size, high lifting capacities, and versatility in moving loads horizontally and vertically.
Key features of Goliath cranes include:
Structure: Goliath cranes are typically supported by two tall steel towers or legs at each end, forming a portal-shaped structure. The horizontal beam, known as the bridge or girder, spans between the legs.
Lifting mechanism: The lifting mechanism consists of a trolley that travels along the bridge and carries the hoisting equipment, which can be a hoist or a grab, depending on the application.
Movement: Goliath cranes move on rail tracks or rubber tires mounted on the ground. The wheels or tracks allow the crane to travel along the length of the structure to reach different areas where lifting is required.
Lifting capacity: Goliath cranes are designed to handle extremely heavy loads, often ranging from tens to several hundreds of tons, depending on the specific model and requirements.
Outdoor use: These cranes are suitable for outdoor use due to their robust construction, which allows them to withstand various weather conditions.
Due to their substantial lifting capacities and versatility, Goliath cranes are indispensable in many heavy industries and contribute significantly to efficient material handling and construction processes.
