Topless tower cranes are commonly used in urban construction projects where space is limited. They can be easily erected and dismantled, making them ideal for projects with tight timelines. The lack of a jib also allows for better visibility for the crane operator, enhancing safety on the construction site.
These cranes are typically mounted on a concrete pad or a tower section, and their lifting capacity can range from a few tons to several hundred tons. They are often used for tasks such as lifting and placing heavy materials, equipment, and prefabricated components during the construction process.
Overall, topless tower cranes offer numerous advantages in terms of efficiency, versatility, and safety, making them a popular choice in the construction industry.
