Power armor frame

The  is a power armor in Fallout 4 and Fallout 76.

Background
The West Tek internalized servo system is the standard chassis for all power armor series. Powered by a back-mounted TX-28 micro-fusion pack generating 60,000 Watts of energy, the HiFlo hydraulics inside the frame increase the operator's strength and carrying capacity. More importantly, it boasts a standard fusion core interface allowing them to be powered from any core found in the wasteland.

Characteristics
The basis for all power armor suits, one can't wear power armor without stepping into the frame. Even without any pieces, a Power Armor frame provides a variety of advantages, like increased carry weight, greater melee damage and the elimination of falling damage.
