Mandrel loading systems and methods

摘要

A downhole tool includes first and second collars, each including a chassis portion. A first axial load device is disposed in the first collar to exert axial force on the respective chassis portion disposed in the first collar. A second axial load device is disposed in the second collar to exert axial force on the respective chassis portion disposed in the second collar. A collar connector is coupled to the first and second collars and compresses the first axial load device.
