How to create a mechanical advantage
The use of pulleys offers a mechanical advantage by de-multiplying the force required to move a mass. In order to gain a mechanical advantage, at least one pulley must be attached to the load.
How to double the pulling capacity
Let’s look at a simple case of block and tackle systems for pulling an object. In the figure below, a pulley is attached to the load and the end of the rope is attached to the winch’s anchoring point. There are two rope lengths, each applying a pulling force of 1,000 kg. The mechanical advantage is x2.
For example, a force of 1,000 kg applied by a PCW5000 will move a 2,000 kg load.
If you handle pulleys correctly, nothing can stop you!
Here are the suggested ''recipes" of required accessories to double the pulling power according to your winch model.
