Actually, pulleys cannot multiply effort force. It can only change the direction of the effort force.
a second-class lever
The simple pulley is the type of pulley that does not have a mechanical advantage.
It's a simple machine, more specifically a second class lever. That means there is a specific effort force, fulcrum and object force.

It is a class three lever. The fulcrum is the end point, the effort is in the middle, the place where you grip, and the load is the things you are sweeping away.
It depends on which type of lever you are using. If it is a Class II lever then the load is between the fulcrum and the effort.
Fixed Pulley and Compound Pulley.
1st class because FLE fulcrum,load,and effort. the load is the bait, the force is where you hold the pole, and the effort is in between.

Gravity does the most of it, but then there's the effort applied by the rider as well. A combination of gravatational force and also downward weight force by the rider.

It has a lever to multiply the applied force, and a wheel/axle, to make it easy to move around.

This type of problems about friction are extremely simple: You just multiply the normal force by the coefficient of friction to get the frictional force.
