Tower Crane Slew Ring

Potain builds more than 60 types of tower cranes to fit a wide variety of job sites.

Tower crane slew ring.

Tower crane jibs are designed to free slew when out of service to avoid high loadings being placed on the crane structure and foundations with risk of failure or collapse. Whether on large infrastructure high rise jobsites crowded urban areas or wide open sites they make it possible to hoist and distribute loads high and far. The base connects to the mast or tower which gives the tower crane its height. Activating weathervaning or free slewing mode on a tower crane essentially allows the crane to slew with its full 360 degree radius freely in the wind just like a flag.

The tower crane use a single row four point contact ball elements slewing ring 01 series and double row ball slewing bearing dia. On top of the slewing unit are three parts. Top slewing cranes are the large construction sites most strategic equipment for productivity. Tower cranes are available with either fixed or slewing towers.

The crane counter weights are located closer to the tower when combined with the angled arm the luffing jib tower crane typically has a higher capacity then the hammerhead crane. It is divided into two types for slewing bearing. Bottom rotation and top rotation.
