What type of crane is a mobile crane with a boom constructed from a steel grid work?

• A. Lattice boom
• B. Jib
• C. Overhead
• D. Weight crane

Answer: (A)

A mobile crane with a boom constructed from a steel grid work is referred to as a lattice boom crane. This type of crane features a boom that consists of a framework of interconnected steel segments, forming a grid-like structure. The lattice design provides excellent strength-to-weight ratio, making the crane both lightweight and robust, which is essential for lifting heavy loads while maintaining stability. Lattice boom cranes are particularly useful in situations that require long reaches, as their construction allows for significant extension without excessive weight. Additionally, they typically have good visibility and maneuverability since they are mobile, allowing operators to position them easily on various job sites. The other types mentioned do not fit the description. Jib cranes typically have a horizontal arm extending from a vertical mast and are often stationary, while overhead cranes (also known as bridge cranes) operate on tracks and are designed for use in industrial settings, lifting loads directly above. A weight crane, which isn't a standard term in the industry, does not refer to a specific type of crane recognized for its lattice boom structure.
