This video was originally filmed in June 2000 when I was working at Dreamworld Theme Park as a maintenance engineer. The Engineering department contracted pilot Scott Menzies owner and operator of Gold Coast Heli Tours to remove and replace the 800kg electric motor from the top of the Tower of Terror which stands 40 stories high. This particular electric motor operates the west side winch for the Giant Drop. This was the very first time the motor was replaced. I believe the lifting strategy is no longer performed in this manner due to OH&S procedural change.
