What is a lattice boom made of?
Think about the structure and weight.
Are crawler cranes suitable for uneven terrain?
Consider the advantages of crawler mounting.
A construction site needs to lift a 200-ton load. If a lattice boom crawler crane can operate efficiently for three months at this site without taking it down, calculate the cost savings if average mobilization costs are $5000 and typical daily costs are $200. Is it economical?
Consider project duration against mobilization expenses in your calculations.
Evaluate the impact of shifting from a lattice boom crawler crane to a tire-mounted crane in a project requiring high lifting if the terrain is uneven. Discuss the pros and cons.
Think about the terrain requirements, stability, and costs against efficiency.
