 Problem Statement: Deriving from the scope of using extendable-ladder's in mobile-truck other custom built automotive devices

                    eg: usage's in fire-engine or fire-brigade, construction-industry, rig drilling in oil drilling industries etc.


Opportunity a: deriving from how a lift or elevator's function or work ...ability to embedded cable into the channel's of the ladder's,
               so as they can be extended or laid using a cable powered by a motor.
      

Opportunity b: do rock climber's ...part and parcel of adventure sports ...are prepared to a free fall ...from a slip-age of grip,
               ...

               well ...a parachute ...potentially that can/may come handy ...based on altitude ...in a emergency??



Note: The above problem statement having been encountered in various scenarios
      and detailed in various 'Proof of concepts' as mentioned in

        ....apply appropriate
      'use-case' modeling, rationalize and arrive at a workable and feasible 
       solution both commercially and techinically viable.
