The heavy loader droid served as a type of labor droid, designed for the purpose of lifting and moving substantial loads, and were frequently employed in conjunction with starfighter ground support teams. A notable example of this droid type is B-U4D, nicknamed "Buford," who served with the Resistance. Another heavy loader droid, B-R72, could be found operating in the vicinity of the Droid Depot located on the world of Batuu.
