....is an expansion,development in the same "family",with the heavy hub pendulum ,and heavy pulley Atwood machine.
The main idea for a heavy hub,is to store/restore rotational inertia as a flywheel.
Heavy hub,is a retarding (and storing) motion method.
So,a heavy hub lever is a first class lever,with a heavy central mass point.
The effort,at the one end of the lever,is imparted as rotational heavy hub work,and effort at the other end of the lever.
Why this possible lever?
Maybe...we can play gravity in a certain manner...

.....is a particular lever,imagined for a specific labor ("effort") :gravity torque difference of a common lever(equal masses,unequal arms ).
To maintain the gravity torque difference,on the same side of the fulcrum/pivot is a next to be problem.
So,a ....heavy hub lever= a common first class lever +a heavy centered mass/massive hub.
The load is intended to pass on,largely to the massive centered mass,attached to a simple lever.

.....as a first class lever,with a massive central point mass,if it works freely,in a gravity fall arrangement,can be considered a particular 9put aside for a some time,delayed...) leverage.
For a common lever,the relation effort-load,is direct,immediate,instantaneous.
For a heavy hub lever,the same relation,between the input and the output,is intermediate and postponed.
