Abstract: It is disclosed a nivellation device making it possible to place ladders horizontally on sloping ground. Such a device comprises a foundation (1) onto which there is secured/placed an elevated area (2), said elevated area (2) functioning as a fulcrum/see-sawing point for a plate (3) onto which plate (3) there may be placed or secured a ladder (I), and said plate 3 being equipped with securing devices (4) that may stay the position of the plate (3) in relation to the foundation (1). Additionally it is disclosed a tightening device for a wire that may be used for securing the nivellation device in a correct horizontal orientation and a device for ensuring that the ladder is not displaced in relation to a house wall.
