tower cranes
Skyscraper building machines
Tower cranes are the tall, fixed cranes seen on construction sites, with a vertical mast and horizontal jib that rotates to move materials across the work area.
They're assembled on-site and grow taller as buildings rise, becoming temporary landmarks during major construction projects.
Three tower cranes dominated the downtown skyline.
