Firstly there is no 'silly question' on the "Forum" - just silly answers..

Seriously, this is how I learn about the marque.

The Quick Jacks on the front and back of the Cobra allow the pit crew to lift the car in the pits.

A frame slips into the quick jacks (both) and then it is pushed down. This frame is not unlike a giant hand truck. Has wheels and a similiar lever/push down action.

I think it was a requirement that the crew person who lifted the Cobra had to stay with the frame to ensure it did not drop. I also feel that they were only allowed to lift either the front or the back. Safety did not allow them to lift both...

Obviously, these are now replaced with on board lifting devices or with air operated lifting equipment used and placed by pit crew.

However, if you watch F1 GP cars come into the pits after a session you will see pit crew use a manual lifting device similiar to the quick jack style. My understanding is these lift the F1 car for a momment allowing on board computer systems to go to zero. Sensors under the car then stop to allow the re set.

They have sensors both monitoring lift and down force etc. etc. You will see this done just prior to the F1 GP car going into the garage.

Guess some of the old style things in racing are still used - the F1 GP cars do not have the quick jacks though!!

Cheers
