Topless tower crane PT6313
PT6313 tower crane is a new type that designed according to JG/T5037-93 (classification of tower cranes).
PT6313 tower crane is new designed self-erecting top slewing tower crane. Advanced technical parameters, max. Radius is 63m, max. Height is 181m. Good looks, popular in China and the world.
Suitable for special work sites. Because no tower head, efficent height of hook and space utilization is improved, so are suitable for special work sites, for example, building of airport, tunnel, workshop and work under high voltage, topkit tower cranes can't do that as flat top tower cranes.
Suitable for work sites that have special requirements to range. Flattop tower cranes have special connection methods, no tower head and pulling rod, that make it's easy and safe to mantle and dismantle hoisting jib in the air, if need to add or reduce the length of hoisting jib, don't need to dismantle the whole jib, can be finished in the air. At hyperbola ooling tower construction site, usually needs to change range. After finishing of builiding, have to pass min. Bore diameter, usually have to dismantle some jibs, sometimes most of jibs that can let tower crane descend. Because topkit tower cranes will be restricted by pulling rod, only can dismantle jibs outside hook point, it's difficult to dismantle pulling rod, flattop tower cranes can do that.
