Roof trusses are essentially the triangular frames that form the top of the house. More than likely, you're familiar with roof trusses and you're interested in a tip on installing and securing your roof trusses. In some cases, it would make sense to use a mechanical pulley system, but in other cases, you may find that it's actually cheaper to just rent a crane for the installation of the roof trusses. Most companies that rent cranes out generally charge by the hour that you need the machinery, so be sure that you have everything you need and lots of support before renting.
Many bridges that use these triangular frames(trusses)are suspension bridges. Like the Mid Hudson bridge for example. Some suspension bridges have their trusses placed below their decks so there is less veiw obstruction. The Mid Hudson bridge and the Whitestone bridge have their trusses placed above their decks and that's why you can see them when driving over them.
