What type of crane uses a lattice design to provide strength and reduce weight?

The lattice boom crane is specifically designed with a lattice framework, which consists of a series of interconnected struts and supports. This construction allows the crane to maintain high strength while significantly reducing its weight compared to solid boom designs. The lattice design is particularly advantageous because it provides excellent load-bearing capabilities while minimizing material usage, making it both cost-effective and efficient in various lifting applications.

Additionally, lattice boom cranes are often used in heavy lifting operations, where their strength-to-weight ratio is crucial. They can reach great heights and span large areas, which is beneficial in construction and industrial settings where large loads need to be moved or placed accurately.

Other types of cranes, such as mobile cranes or hydraulic cranes, may not employ this lattice construction approach as effectively, instead relying on different designs that can either increase weight or limit their load-handling capabilities. Tower cranes typically have a fixed central mast and do not utilize a lattice boom structure, making the lattice boom crane the best answer for this question.
