When I unexpectedly became the possessor of a Celestron NexStar GPS 9.25", I realised I had a mobility problem as my last scope could be carried under one arm and fit easily in the boot of the car!. I wont mention my age but moving and assembling and dis-assembling it is a real physical struggle! So here is my solution for getting it out onto the decking from our sun lounge.
Had the same sort of problem with my 10" LX200, so made a triangular trolley to move it about, the advantage being, only 3 castor wheels needed. Also did same thing for the clubs 12" Newtonian to move it in and out of the container at the hall.
Both trolleys have braked wheel sets so the telescopes can remain on them for use. Sorry I don't have any photo's handy to add.
