Karl:
Thanks for taking an interest in a possible "off label" (pharmaceutical term) use of your company's product.
Please forgive me if you know these terms. ROPS = Roll Over Protection Structure. A folding (tilting) ROPS is just that, a ROPS with a hinged joint in the middle to allow folding the ROPS down in cases where clearance is an issue (e.g. garage doors, low branches in forests, etc).
