TCO's aren't Ramp Agents. Ramp Agents load/unload the bags/cargo - They take care of things on the ramp, whilst the TCO's take care of Passengers and sort out the Loadsheets, Passenger Manifest and counter-sign the Loading Instruction Report.
Part of the TCO job is to also produce loadsheets, both computerised and manual, as well as load planning and flight planning.
