A method to optimize operation of a parcel terminal having a mast and a loader attached thereto, the mast being configured to move horizontally within the parcel terminal and the loader being configured to move vertically within the parcel terminal and the method comprises synchronizing by using a computing device, a horizontal movement of the mast and a vertical movement of the loader based on the calculated horizontal travel time and the calculated vertical travel time. The method enables longer lifetime of participating components as well as longer service intervals of the terminal.
