The silleros, cargueros or silleteros were the porters used to carry people and their belongings through routes impossible by horse carriage. A famous example is the use of silleros by colonial officials to be carried across the Quindio pass in the Colombian Andes.

A porter, also called a bearer, is a person who carries objects or cargo for others. The range of services conducted by porters is extensive, from shuttling luggage aboard a train to bearing heavy burdens at altitude in inclement weather on multi-month mountaineering expeditions. They can carry items on their backs (backpack) or on their heads. The word "porter" derives from the Latin portare.

A porter's gear is typically simple but effective. In this example, the load goes into an oversized basket, or doko, which rests against the back. A strap runs underneath the doko and over the crown of the head, which bears most of the weight. Each porter in this region also carries a T-shaped walking stick called a tokma to take some of the strain off the back.
