Why tower cranes widely used?

Tower Cranes are used because they are efficient at lifting and moving heavy materials while having a relatively small footprint on site. Tower cranes are great at lifting material and moving across long distances. Their reach allows them, in a lot of locations to have unencumbered access to the entire job site.

There are three types of BQ tower cranes, that is hammerhead Tower Crane, Flat Top Tower Crane and Luffing Tower Crane. Each type has different models.
