Cranes lift heavy loads by using a counterbalance in the form of a counterweight or stabilizing components. This counterbalance helps distribute the weight of the load and prevent the crane from toppling over when lifting heavy objects. Additionally, cranes are designed with a stable base and structure to support the weight while in operation.
Without a lever, you cannot easily lift heavy objects, such as rocks or furniture, because you would not have a tool to help you apply force at a distance from the object's pivot point. Levers are essential for multiplying force and making tasks like lifting heavy loads more manageable.
A load can be lifted easily by using a pulley system.
Probably you are using the board as a lever.
A lever is used to lift heavy objects because it magnifies the input force applied to it. By using a lever, a person can apply a smaller force over a longer distance to lift a heavier load over a shorter distance. This principle allows for the efficient lifting of heavy objects with less effort.
A lever works by using a pivot point, or fulcrum, to increase the force applied to lift heavy objects. When force is applied to one end of the lever, it creates a mechanical advantage that allows for the object to be lifted with less effort.

a lever has a mechanical advantage of 5 . how heavy an object can the lever move if a person exerts 100N force on the lever?

The lever.
A jib crane uses a system of pulleys to lift objects as opposed to a lever, like most standard cranes.
A fulcrum in a lever is very important because without a fulcrum a lever isn't a lever , and the fulcrum is the main part of a lever.
A lever! The most simple would probably be a form of lever, and this may also depend on the actual size of the "heavy rock".

A fulcrum would be placed as close to the heavy load as possible. This minimizes the lever arm (and thus minimizes the torque) for the load while maximizing the lever arm (and thus maximizing the torque) for the force you must apply.
A heavy box can be lifted by the simple machine of a lever. Using a plank as the and rod (or similar) as the fulcrum, the box can be lifted, tilted and possibly flipped by applying force to one side of it.
