What for?

The pitman is the main moving part in a jaw crusher, which forms the moving side of the jaw.

A jaw crusher pitman has two supporting points for supporting it in the body of the jaw crusher, the upper supporting parts of the pitman consists of flywheel and eccentric shaft. And the lower supporting parts consists of toggle plate, toggle seat and tension rod.

The pitman achieves its movement through the rotation of the eccentric shaft, so that the jaw plate fixed on it can crush the materials, just like the lower jaw chewing food.
