Abstract

The device comprises two arms B and C articulated to each other by means of pivot 3 and the outer ends of said arms are retained respectively by a base frame E and by the ends of platform D. Furthermore, said arms are combined with counterweights 4 and 5 which perform a swinging motion around pivot 2 which connects said arms to base-frame E. The first counterweight 4 is retained by the first arm, whereas the second counterweight 5 is actuated by the swinging motion of the second arm by means of transmission members 7 and 14.
