This contraption, on the haul-rope, is a de-tensioner. It grips the rope then pulls the middle together making a "bird cage". We set up scaffolding to work off of.
"Bird cage" with clip before inspection. The clip is to be moved back about 18" so we fill this old location with a nylon dowel.

A lifting tool, made in-house, to inspect and grease the sheaves and bushings.
These towers boast spacious and accommodating walkways!
The re-inspected clip the the rope tensioned on it and chair attached. Now run in another chair holding the monster de-tensioner in place on rollers. As with much of ski lift maintenance it is very redundant.

The new location has a core that must be removed. This particular rope is older and like many others of that age it has a hemp braided core.
Raising the repaired bullwheel.
The hollow shaft assembly, now cold, will be placed back in the center. It has a bearing on the bottom and top with spacer sleeves inbetween. The bullwheel still needs to be split for install and removal purposes.
