Narrative:

After landing I performed the normal after landing checklist and assisted with taxi in directions. The captain elected to single engine taxi back; so I shut down the right engine at his direction. When we pulled into the ramp; a follow-me marshaller was waiting for us and brought us to our parking spot. I started the APU slightly late; upon the initial turn into the parking spot. At the marshaller's direction; the captain stopped the aircraft and then set the parking brake. I then let him know that the APU was still spooling up. After that I went heads down to start prepping the ACARS for flight close-out. A short time later; I felt movement on the aircraft; pulled my head up and noticed that the aircraft was moving forward. I simultaneously verbally requested that the captain stop the aircraft. He stopped the aircraft abruptly and we then continued with ensuring that the parking brake was set; shutting down the engine; and beginning engine shutdown checklist flows. Upon exiting the aircraft we noticed that the nose gear had hit the weight cart and was damaged. In order to formalize confirmation that the brake is set after parking we should consider creating a verbal challenge and response for the parking brake on a procedural checklist (I also fly the kc-135 and this is a challenge/response checklist item); also ensure ground personnel give visual signals that the chocks are in place. Re-design parking brake for easier use.
