## Abstract

An extending cargo restraint assembly for a cargo handling system mobile is provided. The extending cargo restraint assembly includes a base assembly, The base assembly includes a primary plunger and a secondary plunger. Responsive to be activated, the primary plunger is configured to extend in a first direction into an opening within a modular container thereby restraining the modular container in a second direction, the second direction being perpendicular to the first direction. Responsive to being activated, the secondary plunger is configured to extend in the second direction within the opening of the modular container thereby further restraining the modular container in the second direction.
