, PT6313

The PT6313 flat top tower crane is a self-erecting top slewing crane designed according to JG/T5037-93. With advanced technical parameters, the slewing crane's maximum radius is 63m and maximum height is 181m.

The topless tower crane is used in a variety of construction work sites. Because there's no tower head, you can efficiently move in the space you are in, such as airports, tunnels, and work under high voltage power lines that topkit cranes can't do.

Flat top tower cranes don't have a tower head or pulling rod and are easy and safe to assemble in air. These construction equipment can even be adjusted in the middle of operation, and after finishing a project, our hoisting jibs are easy to dismantle.
