What are the common problems encountered in hiring cranes for house constructions?
Access, I assume you need a Franna. Possibly for frames and or trusses to the second level or steel beams. You will be limited by reach if the crane can only access the front of the house. In which case you may need a slew crane 30t or larger. Know the weights of what has to be lifted and the distance from the crane to where it will be placed. A crane cannot set up or travel over underground services or recently filled excavation. These things could mean the crane has to set up even further away from the house. If the crane is for unloading trucks, access again. Cranes need to stay about 3meters from power lines which is a common problem bringing gear onto site. While a slew crane generally sets up in one position for all lifts (some can travel) a Franna is designed specifically for pick and carry. It can unload trucks and travel the gear onto site under the power lines. Provided it isn't lifting extra large items. Speak with the provider about what has to be done, it will be all to familiar for any decent company. As long as access is fine and underground services won't hinder you they should know exactly what you need. Be prepared, usually a minimum 4hr hire. If you think the task is going to take longer you need to plan what has to be done and have everything ready for placement. Organization is paramount, you don't want a crane and it's crew sitting there doing nothing because you didn't plan ahead. Hope this helps, I could have been more specific if the question had some details.
It might not be the right size for the job.
