By my calculations it should be able to do the job. However, in a test I made, it managed to lift only about 55lbs...

Tonight we lifted one of the mentors with a CIM and a (slightly modified) off the shelf boat winch. We used a dewalt transmission, however, with an additional reduction between the sprockets. It was pretty quick, with no issues.
