Light Flanged Type Internal Gear Slewing Ring Bearing for LIEBHERR 916 skips( dumpers)

Skips  also called dumpers, are used on construction sites for the removal of excavation and construction materials. Everyday, hundreds of skips are used in large mining excavation fields. One single vehicle can transport a load of up to 400 tons. The skips bring valuable raw materials and excavation materials to the unloading sites, which are often far away, and where the material is either crushed or stored. A tiltable pit combined with a built-in slewing ring allows for precise unloading. Here too, solutions by  Longwei offer the optimal conditions for durable and smooth operation.

Slewing bearings by Longwei  are a key component for controllable axes. The reliability, durability and ease of use of the slewing bearings made by Longwei  not only  benefits the transporting of loads, but also of people.
