Tower Crane Slew Ring

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.

Tower crane slew ring.

It is divided into two types for slewing bearing. Powered by the slewing gear drive the slew ring is fixed to a ball track and is made up of several hundred precisely machined gear teeth. On top of the slewing unit are three parts. 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 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. Tower cranes are available with either fixed or slewing towers. The tower crane use a single row four point contact ball elements slewing ring 01 series and double row ball slewing bearing dia. High capacity top slewing cranes on infrastructure jobs luffing jib cranes that construct supertall skyscrapers topless cranes reshaping our urban environment and hup self erecting cranes transforming residential construction.

Unlike the hammerhead crane the diagonal arm can move in and out from vertical to a 30 degree angle. The base connects to the mast or tower which gives the tower crane its height.

Top slewing cranes are the large construction sites most strategic equipment for productivity. Attached to the top of the mast is the slewing unit the gear and motor that allows the crane to rotate. Bottom rotation and top rotation. Of 1000mm 2000mm 1250mm 1064mm are both standard.

On the fixed tower type the slewing ring is situated at or near the top of the tower and the jib slews about the vertical axle of the stationary tower.
