The correct answer is that lattice boom cranes can be both truck mounted and crawler mounted. Lattice boom cranes are designed with a series of interconnected structural elements that form a lattice framework, typically offering a lightweight yet strong structure. This design allows for versatility in mobility; they can be mounted on trucks for easy transportation on roads, or they can be mounted on crawlers, which give them the ability to maneuver over rugged terrain.

This rugged mobility is essential for construction projects that may require cranes to be moved frequently and to work in various locations. Truck-mounted models are generally used for tasks that require fast setup and flexibility, while crawler-mounted models are beneficial for stability and lifting heavy loads in rough landscapes.

In contrast, the other types of cranes listed have specific mounting and operational features. Telescopic cranes have a boom that extends and retracts but are primarily known for being truck-mounted rather than crawler-mounted. Articulating cranes, or knuckle boom cranes, specialize in lifting and placing loads in tight spaces and usually do not have the capability to be mounted on crawlers. Tower cranes are fixed in place and used primarily in tall building construction; they do not have mobility options of being truck- or crawler-mounted.
