When would you select a Luffing Jib Crane over a Hammerhead Crane?

A luffing jib crane would be selected over a hammerhead crane when operating in congested urban environments or when needing to avoid obstacles near the crane. A luffing jib crane has a jib that can be raised and lowered, allowing it to adjust its reach and avoid swinging over adjacent buildings or other sensitive areas. A hammerhead crane has a fixed horizontal jib, which swings in a fixed radius and can interfere with nearby structures. This control is important to avoid obstacles during operation. For instance, a luffing jib crane is suitable for a construction site in a dense city where the crane must lift materials without swinging over neighboring buildings, which a hammerhead crane cannot do.
