A crane is a first class lever when it is winching in or out the rope attached to a load.
The crane becomes 3rd class lever when it's boom is luffing, i.e. it is being lowererd or raised.
Class 1.
The Class Lever for Pliers is a class 2 lever.
A hammer is a class 2 lever
A wheelbarrow is an example of a second-class lever. The load is situated between the fulcrum and the force. The wheel-barrow is a 2nd class lever as the resistance is in between the force (effort) and the axis. A wheelbarrow is a class 2 lever. The fulcrum is the wheel or wheels in front of the wheelbarrow. You stand behind the wheelbarrow. The load is between you and the fulcrum.
Load is in the center, as in a wheel barrow or a bottle opener. Having an acronym might help remember which class is which. For example: 3-2-1 - ELF! means that for a class 3, the effort is in the middle; class 2, load in the middle; and class 1, fulcrum in the middle.

The Class Lever for Pliers is a class 2 lever.
There are three types of lever, with examples as follows: A seesaw (teetertotter) is a Class 1 lever A wheel barrow is a Class 2 lever A pair of scissors is a Class 3 lever
class 3
A lemon squeezer is a class 2 lever, where the load is between the fulcrum (pivot point) and the effort (squeezing the lemon). This type of lever allows for increased force at the load end with less effort.
A class 1 lever is generally considered to be more efficient than a class 2 lever, as it allows for greater load displacement with less effort. In a class 1 lever, the fulcrum is positioned between the effort force and the resistance force, resulting in a mechanical advantage that allows for easier movement of the load.
On the lever
Class 1 and Class 2 levers always have a mechanical advantage greater than 1. In a Class 1 lever, the input arm is longer than the output arm, while in a Class 2 lever, the output arm is longer than the input arm, resulting in a mechanical advantage greater than 1.
