For upgraded container undercarriage structures, the front bottom cross beam works with gooseneck tunnels and main gooseneck beams to reinforce the overall frame strength and simplify truck loading positioning. The front bottom cross beam connects with threshold sills and bottom side rails via corner castings to form a rectangular base frame. Multiple evenly spaced bottom cross beams are welded between two bottom side rails to connect and support container wooden floor panels.

As an essential part of the container undercarriage, the front bottom cross beam delivers dual supporting and connecting performance. It assembles with other structural fittings to build a rigid frame that maintains stable performance during container loading and unloading. The beam effectively withstands external forces and vibration generated in transit to prevent cargo damage. When matched with gooseneck beams and gooseneck tunnels, this cross beam further upgrades undercarriage structural rigidity and enables accurate positioning during container truck loading operations.

Suitable for general dry cargo containers, including standard dry containers, special containers such as tank containers, refrigerated reefer containers and other ISO standard shipping containers.
