Abstract
A wagon for carrying a lifting cradle having a wagon chassis and at least one pivotable body mounted to pivot about an axis for pivoting and guides for receiving at least one lifting cradle. Components for locking the lifting cradle to the chassis include a shaft fixed to the chassis and disposed along the vertical axis for pivoting, two attachment arms disposed on either side of a longitudinal plane of symmetry and mounted on the shaft to pivot between an unlocking configuration and a locking configuration, the arms including noses projecting laterally each adapted, in the locking configuration, to engage between two substantially transverse sides of a housing provided on the side beams of the lifting cradle and, in the unlocked configuration, to be outside the housings. Elements to control and guide the movement of the arms and to block the arms in the locked configuration are attached to the arms.
