A derrick is an artifact used to lift weights. Description
It consists of a framework of three beams, two of them assembled at an acute angle and a third forming a tripod with the other two to give stability to the structure. It has a pulley suspended in the center and a lathe where the rope is wound with which the weight to be manipulated is raised.
Sometimes a Roman scale is used to weigh it.
In addition to the construction, it is used for other functions such as traditional cork weighing.
