Abstract
A lower block, in particular for lifting tackle, having laterally arranged, rotatably mounted pulleys and a load hook which is mounted rotatably about a vertical axis and a horizontal axis and is connected via a connecting element to the pulleys. In order to reduce the overall height and the work involved in assembly of the lower block without correspondingly reducing its load bearing capacity, journals are formed integral with the connecting element and are arranged at opposite lateral ends thereof for supporting the pulleys. The load hook is arranged and axially secured in a recess defined in and open toward the bottom of the connecting element.
