Abstract: A carrier includes a chassis that is configured to travel from a loading point to an unloading point and a tillable platform is mounted on the chassis. A resilient piston is connected between the chassis and the tillable platform, the piston configured to store energy when the platform is rotated from an unloading orientation to a loading orientation. The platform, when in the loading orientation, is configured to stably support one or more items that are loaded onto the platform at the loading point. A restraining mechanism is configured to maintain the platform in the loading orientation and a triggering mechanism is operable to release the restraining mechanism, releasing the stored energy of the piston to exert a restoring force to tilt the platform from the loading orientation to the unloading orientation.
