Ants can lift many times their own body weight and work together to move food.
The longer version
Strength in small animals is mostly a matter of geometry. Muscle force scales with cross-sectional area, while body mass scales with volume, so as an animal gets smaller its strength-to-weight ratio rises sharply. An ant is operating far up that curve.
The neck joint and the exoskeleton also help, giving a rigid anchor for muscles to pull against and protecting against buckling. Cooperative transport adds another layer: many ants grip one item and pull in the same direction, and their combined effort greatly exceeds what any individual could shift. Chemical trails recruit more workers as needed, so the load effectively scales with the size of the workforce.
