Powered Lifting Table

Abstract

Various configurations and systems for lifting tables are provided. The lifting tables may include legs that are extendable and retractable. The legs may include various components, such as L-shaped internal brackets configured to hold lubricants to provide for smooth lifting operations, cable management configurations, and/or other features to improve the operation of a lifting table.
