The semitrailer is joinable to a tractor provided with a vertical towing gudgeon, is supported at its back end by a wheeled structure, and comprises a chassis having longitudinal members and crosspieces, which define a horizontal loading platform, and further having uprights rising from its forward end. A towing bar is hinged on the uprights around a first horizontal and transversal hinging axis. A compensating hydraulic cylinder is articulated between the chassis and the towing bar. A coupling is articulated to the towing bar forwardly of the first axis, for hinging around a second horizontal and transversal hinging axis, and is provided with a bushing that is transversal to the second hinging axis and is rotatably engageable on the towing gudgeon of the tractor.
