Rotatable cargo platform for trailer vehicle

摘要

A modular trailer vehicle is provided comprises a wheeled trailer chassis having a forward vehicle attachment, along with a rotatable cargo platform attached to the chassis for supporting cargo hauled thereon. The rotatable cargo platform is rotatably mounted to a hydraulically actuated turntable, which facilitates rotation of the platform from a position in alignment with the chassis to a position wherein the loading ramp is positioned off to the side of the trailer. The platform is capable of complete rotation about a central axis defined by the turntable center, wherein at least two hydraulic arms actuate the turntable, which supports the rotatably platform using a bearing assembly attached to the trailer chassis.
