In tower cranes, the foot frame is used in 3 different ways as leveled fixed foot, movable foot and anchor frame (embedded in concrete) foot according to the usage areas.

Tower crane foot type is determined according to the construction site environment and the duration of the project. In long-term projects, if the tower crane does not need to be moved from its place, the feet are buried in the concrete with the anchor chassis. If the project period is not very long or the tower crane needs to be relocated in the medium term, fixed legs are used. The feet are fixed with concrete weights. If the tower crane needs to move, movable rail system feet are preferred.
