Turntable for Link-Belt LS98

The turntable, also referred to as a slewing ring, is a large structural and mechanical component that enables the superstructure of a crane to rotate 360 degrees relative to the undercarriage. It is designed to support the combined axial, radial, and moment loads generated during heavy lifting and slewing cycles, ensuring the crane can position loads with precision. This component is identified by part number 1A0629.

This turntable is specified for use on the Link-Belt LS98 crane. It consists of two concentric rings with rolling elements, such as balls or rollers, positioned between them to facilitate smooth rotation. The assembly includes seals to protect the internal rolling elements from environmental contaminants and features a lubrication system to manage friction between the contact surfaces.

In heavy machinery, the slewing ring serves as the primary interface between the chassis and the upper works. By maintaining the structural alignment of the crane while allowing for controlled rotation, it ensures the stability of the machine during operation. Regular maintenance, including consistent lubrication and monitoring for play, is required to maintain the mechanical integrity of the slewing system.
