Each basin is supported both by one end of the beam and by one end of the homologous transmission and remains horizontal thanks to a judicious calculation of the ratio between the lever arms. This is the first equal-arm balance system with compound beams invented to overcome the faults of the Roberval. The first patent was issued on July 14, 1845 to the great Lyonnais builder Joseph Béranger. Thereafter this system knew 2 variants and obtained 5 admissions: - pendulum balance (27/03/1848), - simplified pendulum balance (08/09/1854), - low balance Catenot-Béranger (24/05/1864) , - simplified Béranger balance (Trayvou) called "knife" (17/04/1889), - Béranger balance with four supports (09/05/1902). The litters sold generally range between 1 kg and 60 kg. Most models are flail with two parallel arms. The original pendulum scales are mounted on a closed box. Simplified pendulum scales are most often open-based, made of cast iron (straight or violin shape). The balance index has horizontal lugs facing each other in the shape of birds or chimeras attached to the pelvis supports. Wide and stable, these scales were appreciated for high capacities. The original pendulum scales were frequently used in shops as prestige counter scales thanks to the existence of luxury models. Simplified open-based pendulum scales were intended more for markets.
