Rocker Rope Grab

NOT INTENDED AS A LIFE SAFETY DEVICE!

If you've ever worked at heights, it's wise (essential) to work with height safety equipment to protect you from dangerously falling; effectively life protection.  A key component in the height safety equipment is the rope grabber attaching you to your safety line.

Not only do you want to protect yourself from falling far, this applies to equipment that you work with, eg. boxes, power tools.  My 3D design is aimed at producing a rope grabber to attach accompanied equipment to a safety line, too.

I provide two versions of the grabber, one set of parts for 9 and another for 11mm rope.  My rope grabber is optimised for use with Kernmantle rope.  Lesser grade rope can compress too much under load and potentially slip.

The 9 and 11mm grabbers share similar parts, each spaced differently for the matching rope size.  Apart from the tope face panel, these parts are not interchangeable.  The grabber parts are held together with a M6 x 25mm nut and bolt.  I also use a thread locker to prevent the nut from working itself loose.  A nylon lock nut can be used, too.

For my strongest test, I've printed my design in Prusament Poly Carbonate Carbon Fibre and am amazed at how robust the rope grabber was; it appears indestructible.  Sorry, no measurement tests to share, but a reminder that this design is not intended for people to protect themselves with!

See included photos for assembly details.

My print is made in PC Carbon Fibre 1.75mm Prusament gray filament, with 0.2mm layer height and 100% infill on a PRUSA I3 MK3S printer.  Print supports are not required.

I hope you can find this design useful, too.

Remember to leave me some feedback or even a tip to keep me enthused to make more of these drawings.
