Method for forming a modular convoy for outsize loads, modular convoy and trailer for such a convoy

A modular convoy (1) for outsize loads is formed by connecting a first tyred trailer (3) and at least a second (4) tyred trailer to each other, having first (6) and second hydraulic suspensions (10), respectively, which are reciprocally different; each of the first suspensions (6) having a first lever transmission (7) and a first simple-acting, linear hydraulic actuator (8) to exert on the ground a first load support action, and each of the second hydraulic suspensions (10) having a second mechanical lever transmission (11) and a second double-effect, linear hydraulic actuator (12), the chambers (15)(16) of which are connected to the same feeding line (21) for exerting on the ground a second load support action which is substantially equal to the first support action.
