The picture has been taken from a balcony zooming into these men carrying Jesús.
This occurs during the Holy Week…at this time I was in Málaga (South of Spain) at my cousins’ house. It was the first time for me to live this religious period in Spain. It is kind of difficult to explain but I found a website that explains it quite well, here is what they say:
"Spain celebrates Easter Week much more than most European countries. During the whole Holy Week, (Semana Santa), street processions are organised in most Spanish towns each evening, from Palm Sunday to Easter Sunday.
People carry statues of saints around on floats or wooden platforms, and an atmosphere of mourning - which can seem quite oppressive to onlookers - and the Easter week processions end with Easter Sunday, a day full of light and colour when church and cathedral bells are heard ringing throughout the country.
The people who carry the weight of the floats are called "costaleros" and are expected to carry these "thrones" with solemnity and grace. They use a small cushion, "costal" to protect themselves from getting sores from the wood rubbing against their skin during the long processions.
( From: http://www.euroresidentes.com/Fiestas/semana_santa.htm )

In this case, what you see are the "costaleros" except that sometimes the frame is made of alloy and others are made of wood.
I hope this is a good explanation to help you understand ;-)

Thank you for your comments, I am glad you all like it :-)
