The load at the tip of the adapter is 4x greater than a Forklift when using a rear axle SpindleWich

To counter this moment force, we use extendable bars up to the Casting Corners.

90% of the load is transferred up to upper corners, which enables TriWich to carry fully loaded containers with tractor or other tug.

Thus we call it the 50k bar (100k containers)
