Subject: Automated Parking Garage Energy Usage

Your article (Robotic Parking Garages Save Space But There is a Catch-22 - Energy Usage)stated "one should also understand that robotic parking structures use a lot of hydraulics". I wanted to correct a misconception. The automated garages built by Robotic Parking Systems use NO hydraulics.

Subject: Robotic Parking Systems Inc. does not use hydraulics

I will check out Robotic Parking Systems with no hydraulics, and I actually believe that would be a better way to do it, because if hydraulic lines often break and that would be a real problem as it would ruin the paint on all the cars the hydraulic fluid sprayed onto, plus the system could be stuck half-way up or down, and that could be serious, hard to repair and complete chaos too! Thank you for your comments.

Lance, good article however I wanted to also point out that the FATA Skyparks system doesn't utilize hydraulics either, and many suppliers are moving away from hydraulics due to their performance characteristics at various temperatures.

In addition to the energy consumption there is also a benefit of using Regenerative Energy devices (such as brakes) on the vertical lifts. This adds some cost as well, but depending on the size of the system the costs could be insignificant.
