Description

  The present invention provides a rotary casing in which a frame having an outrigger is supported by a rotating body having a chuck for gripping the casing in a rotatable and elevating manner, and a rotating body rotating motor and a rotating body elevating jack are provided. The present invention relates to a method for loading and unloading a pushing device onto a transportation platform such as a truck or a trailer.

  Conventionally, when a heavy-weight rotary casing pushing device (hereinafter referred to as “this device”) is loaded onto a loading platform, the device is lifted by a large crane and loaded onto the loading platform.

However, there is an inconvenience that a large crane must be prepared at the work site every time loading and unloading. To solve this problem, first of all, even if the vertical width of the frame of this device is considerably long, the horizontal width is set to the trailer. As shown in the following patent document, an outrigger with a long expansion / contraction length is attached to the four corners of the frame body so as to be movable in the lateral direction. Is moved laterally outward to widen the distance between the outriggers facing in the width direction, and then extended, and then the self-propelled vehicle is moved in a direction orthogonal to the lateral side of the frame to pass between the left and right outriggers. Next, the respective outriggers are reduced to carry the device on the self-propelled vehicle, and the outriggers are moved laterally inward to make the horizontal width of the frame the transportable width. And integer, those transporting the apparatus by the driving of the motor vehicle has been proposed in this state.
