twogirder

The term "twogirder" typically refers to a type of overhead crane that utilizes two main bridge girders to support the trolley and hoist. This design is common in industrial settings for lifting and moving heavy loads. The two girders are usually spaced apart and run parallel to each other, connecting the crane's end trucks which travel along a runway. This configuration allows for a wider span and can distribute weight more effectively than a single girder crane, especially for heavier applications.

The trolley, carrying the hoist, moves along the top or between the two girders. The specific arrangement of the girders and how the trolley interacts with them can vary depending on the crane's design and intended use. Advantages of a twogirder crane often include higher load capacities, greater stability, and the ability to achieve longer spans compared to single girder cranes. They are frequently employed in manufacturing plants, warehouses, shipyards, and other heavy industrial environments where robust lifting solutions are required. The selection between a single girder and a twogirder crane depends on factors such as the required lifting capacity, the span of the area to be covered, and the available headroom.
