Home construction companies nowadays frequently use heavy equipment to help volume builders churn out homes in around 3.5 months. This GENIE GTH-844| Telescopic Handler was being used to facilitate some roof work on the two story structure you see in the picture below.
Its lift and reach capacity is 6000 and 2000 pounds respectively with a max height of around 43 feet. It was apparently cheaper to rent the handler to lift the particle board for the roof than more manual methods. I bet they used the handler to lift the composition shingles to the roofers as well.
Beau Grassl, who I believe leases these bad boy powerful, elevated fork lifts, can provide interested construction companies with rental and pricing details.
