A lattice boom crawler crane is a crane that gets its name from the W or V shaped lattice design of the boom. The benefit of this design is that it decreases the total weight while still providing maximum support for heavy loads. Other lattice boom crane parts include the crawlers, hoist, cab, sheaves, and wire ropes. Crawlers are the equivalent of wheels on a car—they move the crane along the ground. The hoist is what moves loads up and down. The sheaves make up the pulley system that holds the wire ropes, and the wire ropes extend to latch onto objects.[1]
Of the most commonly used cranes in modern-day construction, the crawler crane is the largest and can lift loads in excess of 2,500 tons. This crane is mounted on an undercarriage with tracks, which ensures mobility and stability. Their mobility allows them to move up and down, side to side, and front to back. Their tank-like treads ensure they move easily through construction sites.[1]
Since the treads provide stability they do not require the use of outriggers. However, they do require the most on-site assembly out of all the mobile cranes. This can include attaching tracks, assembling the lattice boom, and adding counterweights.[1]
