A spreader is a hydraulic tool that is designed with two arms that come together in a narrow tip, and that uses hydraulic pressure to separate or spread the arms. The tip of the tool can be inserted into a narrow gap between two vehicle panels (such as between two doors, or between a door and a fender), then operated to create or widen an opening.
A jaw or toggle crusher consists of a set of vertical jaws, one jaw is kept stationary and is called a fixed jaw while the other jaw called a swing jaw, moves back and forth relative to it, by a cam or pitman mechanism, acting like a class II lever or a nutcracker. The volume or cavity between the two jaws is called the crushing chamber.
The jaw bucket works with the hydraulic system of the excavator. The hoses to the excavator, for intake and drain the oil are connected directly to the crusher bucket. A hydraulic valve block regulates the oil flow and the oil pressure to the correct amount of the hydraulic motor leave. The movement is transferred to one of the two crushing ...

The bolt is used to set the jaws to a size slightly smaller than what is to be gripped. The jaws are then closed on the gripped object. Because of the lever action the jaws move only slightly but with much force. Locking pliers have four advantages: Their lever action is stronger than that of ordinary pliers, so they can apply much more force;
