thanks everyone for the answers. In my country the key grip is responsable for the dolly, cranes, camera flags, riggings, butterflies but the light supports and difussion are electrician´s. Here, the key grip needs to prepare an equipment list incluiding all the items that we will use during de shoting days based on the tech recce, if you missed something is your own problem, because we dont use to have the truck loaded with default gear.
