If you are a builder or a project manager, and have a project that is going to use roof trusses, specialty crane services can help. They can provide you with many things that your project may need, such as large boom cranes that can set bundles of trusses in place. If this is one of your first projects using trusses or cranes, there are some things that you may want to know first. Here are five tips to help make setting your roof trusses much easier:
1. Plan The Packaging Of Roof Trusses With The Truss Company
When you plan to have your roof trusses built, you can also talk with the truss company about bundling them. Usually, trusses are bundled in large sections for different parts of the roof. These bundles may be too heavy for a crane to lift and set on the roof. You can ask the truss company to bundle them in smaller bundles as well. You may want to have them bundle the trusses in groups of three to five, which will be lighter for the crane to lift and easier for workers to set in place. The king trusses you will want to have separate from these bundles, because these are the trusses that have to be set first.
2. Find A Crane Company With The Type Of Crane You Need For Your Project
There are many different types of cranes. Boom cranes will be the best for setting trusses, but you need one with a boom that is long enough to reach to the furthest parts of the roof. Ask the crane company about the specialty cranes they have available, and the reach that they have. The load is also an important consideration when setting bundles of trusses, and you will need a crane that can handle the load of a bundle of trusses without any problems.
3. Make Sure Workers Are Trained In Crane Signals And Safety
When working with cranes, safety is important. Crane signals are also important to guide the crane operator to where bundles of trusses need to go. On the team you have setting the roof trusses, you should have at least one person with experience using crane signals. It is also a good idea to have all workers on the project have basic crane signal training. You may also want to ask the specialty crane service if they can send a signal person with the operator when you are having the roof trusses set on your project. It is also important that all workers have basic crane safety training before you begin your project.
4. Set The First Trusses Before Moving Others In Place
The first step in setting the roof trusses is to set the king trusses in place. These are the trusses that are used as gable ends or as the beginning of a hip or valley roof. You will want to set the king trusses and then several of the common trusses, then brace them in a level position. These can then be used to lean small bundles of trusses against. It is important not to put too many trusses in one place, or lean them against the king truss.
5. Move Truss Bundles Into Place To Be Set
The smaller bundles of trusses can be set in place once you have the king trusses in place and the beginning of the roof system is braced. You can set every third or fifth truss, and then have the crane set the small bundles into place on the roof. If you have hips in the roof design, you can set the first hip truss, so workers can begin installing the smaller pieces of the hip ends. Once all the bundles are on the roof, workers can beginning setting the trusses in place. You may want to have the crane help with moving the largest common trusses, which may be to heavy for workers to move in place.
These are some things that can help you when setting trusses with a crane service. If you need help planning your project, contact a specialty crane service like Winslow Crane Service Co to discuss the needs of your project.Share
