A frame or structural cargo frame is a number of profile steel integrating crossbars and crossbeams that united offer the necessary resistance for maneuvering heavy lifts safely and efficiently.
The frame crossbars are united with crossbeams and the strongest one (sometimes called bridge) is normally assembled in front of the frame to endure the mechanic advantage and do the cargo performance. This can be a motorized electric type (winch or electric hoist) or manual.
