My mate Chicken Tim sees it on CCTV, jumps in his truck and Mr Fox goes down in a hail of buckshot...not very Disney is it...!

Hi there, Thanks for your response, I probably posted before I thought enough about this! I derived my drawing from a standard reversing contactor diagram and the info that came with the motor/gearbox. Are you familiar with this sort of stuff? Am I on the right lines? The interlock mentioned seems to me to be achieved with my last drawing (003) but I am seeing reversing contactors online with mechanical interlocks, does this do away with the need for this? What sort of additional safety devices are we talking about here? Oh & btw I have added a stop in series between the overload NC contacts and the emergency limit switches. Thanks John.I can't see any interlocks or safety device either. Did you get this resolved?
Ok here is another go, I rectified at least one mistake. The coil of the open contactor is energised via NC aux contacts of closed contactor and vice-versa, is this not interlocking?
The doors themselves are lightweight plywood being winched up or lowered down under gravity, I doubt they could even bruise a chicken. Is the 'safety device' being mentioned to stop the doors causing injury?
