Can't they just have one carriage thing get the people to the lift and have them step out of the carriage, walk 2 steps towards thee lift and continue from there? That seems like a much cheaper and safer solution to me.,(reply>), +Snolferd How would that be safer. People walking close to exposed machinery is a recipe for disaster. The amount of extra safety systems required would also be a lot more expensive than the latching system between the cart and the lift. No, it's better to shut them all in a box in one end, and not let them leave it until they get out the other.
