Technical Details

I acquired my Offset Ascending Rack (OAR) from the inventor, Gordon Svedberg in 2010.

My Offset Ascending Rack is 142 mm. tall, 119 mm. wide, 45 mm. thick, and weighs 416 g. The OAR consists of a central spine and three rather complex arm assemblies, as follows:

The spine is stamped "OAR" and "009" (the serial number). Stock material markings on the top arm show that it is made from 6061-T6511 aluminum alloy.

Comments

The OAR is designed for arborists. They can use it to ascend or descend. Rather than describe the motion, I'll refer the reader to two of the inventors YouTube videos. One shows how to use the OAR, and another shows an OAR drop test.

The OAR workmanship suggests that it was done in a home shop, primarily with hand tools; however, the inventor is marketing these.

Hundreds of cell phone users complained and asked me to for a simpler, mobile friendly site. In particular, they wanted me to limit each page to a small number of pictures and minimize my use of text. This new site provides what they asked for.
