A topless Tower Crane, also known as a flat top tower crane, is a type of construction crane that does not have a traditional horizontal jib or boom. Instead, it features a horizontal machinery arm that is used to lift and move loads. The absence of a jib allows for easier maneuverability and greater flexibility in confined spaces.

Operation
angle seat piston valve is a pneumatically-controlled valve with a piston actuator providing linear actuation to lift a seal off its seat. The seat is set at an angle to provide the maximum possible flow when unseated. Angle seat piston valves are particularly suited to applications where high temperatures and large flowrates are required, such as steam or water. When used in reverse some models of angle seat piston valve will eliminate water hammer when operated.

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.
