Shipping containers are designed to be lifted and stacked on cargo ships, plus they’re built to withstand the rough weather of international sea travel. Stacking shipping containers for sale is also commonly seen to create structures on land such as housing and shipping container offices. Whether stacking containers on a cargo ship or on land, knowing how to do so safely and correctly is important. Let’s take a look at what must be done beforehand and during the stacking process.
Inspect The Container
Make sure the flooring of each shipping container is structurally sound. Inspect the corner posts for any damage. Check the unit for any signs of damage or wear such as dents or rust. One-trip and cargo-worthy containers should be good to go. Wind-and water-tight containers should be inspected carefully before stacking. See more information about all shipping container conditions. Also, be aware that shipping containers have a maximum stack load that must be followed, which is listed on a unit’s CSC plate.
Use Corner Posts
A crane is the best way to stack containers. The four corners at the top of a container, called corner castings, were designed specifically for cranes to use and lift units. When stacking, containers should be aligned corner post to corner post with all four corners of the top unit sitting directly on top of the bottom unit’s four corners. If containers of different sizes are stacked, the bottom container should be the bigger unit for maximum stability.
Lock Containers Together
When traveling overseas, preventing containers from moving is essential, but locking stacked containers on land is still important. When containers are stacked on cargo ships, lashing rods are used to lock them together and prevent them from sliding around while being transported. Twisting rods can add additional security by locking the four corners of each container together.
Stacking Safety
Although cranes are ideal for stacking containers, some forklifts can be used. Container forklifts can handle 20ft shipping containers and 40ft shipping containers. But be aware, some types of forklifts cannot handle the job, so a crane will be needed. Only properly trained and certified forklift operators should be operating equipment.
