If you have very large boulders or rocks on your property and they are in the way of a project that you want to start, you'll want to look into getting a crane and relocating each one. With a small crane you should be able to place the boulders in places that are more suitable for the property, or you can get rid of them. Here are some of the options to consider, and then when you pick out your solution can rent the crane.
There are many people that will use large rocks or boulders as décor around their property, or to stop water or rock fall. If you think that you could make a profit off the large items that are on your property, place and add with the pictures. They may want to bring in their own crane and hauling service to get the rocks moved to their property safely and quickly without complications, and then you won't have to pay for the services.
You may want to use the boulders as a wall to create privacy, or to use them as a barrier to keep people from driving through your yard or into your home. If you think you want to keep the large rocks on the property, use a crane and place them along the driveway or at the front of the property line, so people can't drive a vehicle in. This could also help prevent a crashing vehicle from crashing into your property.
If you want to move the boulders so they act as a barrier from a small creek or river near your home, or to add some style to a pond or water feature you have, get the crane so you can put them in the most ideal location. When you take the time to rent the crane it gives you more time to move them and around and decide where they will be located best.
If you have large rocks or boulders that you haven't been able to do anything with because you don't know how to move them or because you haven't taken the time, find a crane rental service in your area so you can get these moved to improve your property. The sooner you find the best option for you, the sooner you can get the pieces moved around and you can enjoy your property.
