What is the name of the industrial crane composed of a hoist trolley traveling along a horizontal boom?

The industrial crane that is characterized by a hoist trolley traveling along a horizontal boom is known as a jib crane. In a jib crane configuration, the horizontal boom, also referred to as the jib, is attached to a vertical mast. This design allows for a flexible range of motion for the hoist trolley, enabling it to lift and move heavy materials efficiently across the area covered by the crane.

The jib crane is widely used in various industrial applications due to its relatively simple design and ability to operate in confined spaces. The ability of the hoist trolley to move along the horizontal boom provides excellent maneuverability, making it ideal for tasks that require precision in lifting and positioning loads.

In contrast, a gantry crane, while also used for lifting, has a different structure with its own unique capabilities. A lattice crane typically refers to a type of crane that has a truss-like framework, which is engineered for greater lifting capacity but does not feature a horizontal boom in the same manner as a jib crane. Lastly, rough terrain cranes are designed for mobility on uneven ground, which also differentiates them from the specific function and setup of a jib crane.
