Can these compact cranes be used indoors?

Yes, both types are highly suitable for indoor use. Spider Cranes are particularly effective indoors due to their narrow chassis, ability to pass through standard doorways, and electric power options that eliminate emissions. Mini Crawler Cranes can also work indoors if equipped with a battery or electric motor. When choosing a crane for indoor applications, consider floor load limits, ceiling height, and ventilation if you're using a diesel-powered model.
