300lbs of counterweights strapped to the doors would take up a good bit of space. Pulley systems would need to either be 1 to 1 or would need some space to fall below the garage floor or to be stored above garage door height.

They seem far safer, longer lasting, and cheaper and easier to repair than springs, but are more expensive to install, take up more space, and probably cost more all in all compared to springs.

I found this that also goes into it:

That looks super cool actually, like passing the Pillars of Hercules every time I drive https://hermco.ca/wp-content/uploads/img_14.jpg

You know, that design makes a lot of sense, since the door would be mostly horizontal by the time the pulley got close to bottoming out the motor would still be able to move it.

I bet those tubes go below the foundation though and god help you if the cable breaks and you have to fish those weights out to reattach it.

Maybe there is some easily reachable latch point on top or some sort of fluid pump port that will make it easier on you?
