A container opening tool is provided, including: a main body, a first engaging portion, a second engaging portion, a third engaging portion and a fourth engaging portion. The main body defines a longitudinal direction and includes a first end portion and a second end portion disposed on two sides of the main body. The first engaging portion is disposed on the first end portion. The second engaging portion is disposed on the first end portion and includes a first mouth opening in a first direction lateral to the longitudinal direction. The third engaging portion is disposed on the first end portion and includes a second mouth opening in a second direction lateral to the first direction and the longitudinal direction. The fourth engaging portion is disposed on the second end portion and includes a through hole extending in the first direction.

Methods and apparatus for rotating a container delivered to a container manipulation system on a conveyor are described. In some embodiments, first and second carriages are positioned on opposite sides of the conveyor, each carrying respective forward and rear clamp arms. Each clamp arm is selectively independently moveable and carries at least first and second vertically spaced-apart wheels. All of the wheels are engageable with the container on the conveyor. At least two wheels on the first carriage are power-driven and selectively rotatable. The remaining wheels are free-spinning. Additional methods, systems and apparatus are also disclosed.
