NAG is a company in Grand Theft Auto: San Andreas that manufactures heavy machinery. A NAG crane can be found at the Angel Pine Junkyard in Whetstone. However, it cannot be entered or driven and exists solely as a static prop. Due to its static nature, it is slightly oversized. This implies that if it was drivable, it would be too big to drive on the road. Judging by its name and yellow livery, NAG may be based on the Caterpillar construction manufacturer, which is often shortened to "CAT".
