Abstract
A telescoping tube assembly includes a frame and a first longitudinal tube section mounted on the frame. A second longitudinal tube section is disposed within the first longitudinal tube section and adapted for telescoping motion into and out of the first longitudinal tube section. The telescoping tube assembly includes a cabling system that includes a top pulley assembly and a bottom pulley assembly, the bottom pulley assembly adapted for movement in response to the telescoping motion of the second longitudinal tube section. One or more cables extend from the remote end of the innermost longitudinal tube section and traverse the top pulley assembly, the bottom pulley assembly and are fixed relative to the frame.
