I'm a Vancouver based YouTuber and adventure blogger, and got to climb to the top of a construction crane.

Mega Cranes took me up 200 ft. to the top of their tower crane on a construction site in Burnaby, BC. For me to climb the tower required me to have my Fall Protection Certificate, which I took online prior to climbing the crane.
Something else I needed was a bunch of security equipment, including:
Hard hat: http://amzn.to/2qeyKn8
Safety vest: http://amzn.to/2poPofw
Steel toed boots, harness and my Fall Protection Certificate.

Thanks to Mega Cranes and Mike for having me come up. http://www.megacranes.com
