Abstract: A telescoping mast assembly includes two longitudinal tube sections, the second disposed within the first, and adapted for telescoping motion into and out of the first longitudinal tube section. A drive assembly is joined to the first longitudinal tube section and to the second longitudinal tube section and operably configured to drive the second longitudinal tube section relative to the first longitudinal tube section. A support brace is mounted under the second longitudinal tube section, and is configured to help support the weight of the telescoping mast and reduce the torque on the telescoping mast at the base due to the large mass of the mast plus its cargo at often a large radius of extension. This thereby enables the telescoping mast to handle larger masses at longer radii of extension with high levels of performance and reliability.
