<p>A weight lifting device comprises a mast (1) consisting of four vertical rods (2, 2', 3, 3') two of which are provided with cavities containing, inside them, carrying elements. The rods (3, 3') with the carrying elements and the rods (2, 2') are oriented in pairs symmetrically in relation to the vertical axis (5) of symmetry of the mast (1), whereas the weight suspension (10) consists of a quadrangular frame embracing the mast (1) and formed by two parallel beams (11, 11'), whose central parts are rigidly connected to corresponding cantilevers (9, 9'), and by two parallel rockers (12, 12') hingedly connected by their ends to the ends of the beams (11, 11').</p> |
