Batch setting of large blocks using a heavy-duty carrier
Batch setting of large blocks using a heavy-duty carrierMaking narrow areas passable by changing the motions of large carriers on both sides
This method is adopted in many projects for erecting girders on express way or major roads, located with constrained conditions such as a lack of work space for setting up, insufficient capabilities of large cranes, or limited time for erection (e.g. one-night erection.)
Erection work in such cases requires special techniques to transport girders to the correct erection position, avoiding obstacles that may exist on the left, right, top or bottom.
Consequently, the relative position of the carriers can be independently adjusted for pitch and roll, which has expanded the feasible scope of erection work in the case that the width of the transport pathways are constrained.
