  • Patent number: 5429472
    Abstract: A mechanism for lifting and hauling of a container or the like onto or from a ramp, a tipping body of a lorry and to or from a location which is not easily accessible for heavy haulage vehicles and/or heavy lifting gear includes a hauling arm secured intermediate first and second ends of a shaft and levering arms also attached to the shaft. The shaft is pivotably connected to locking elements adapted to be secured to lower corners of the container at one end thereof. With this arrangement, when the locking elements are secured to the container and the hauling arm is manipulated in order to rotate the shaft relative to the locking elements, the levering arms engage a supporting surface for the container and continued rotation of the shaft causes at least a portion of the container to be lifted from the supporting surface for hauling of the container.
