We've hung thirty concrete blocks on this TS4-140, each block weights 4.28 lb, total weight is 128.4 lb. The average load from a standard washing machine is 12 lb.  The TS4-140 will take at least four machine loads, even without going to the max loading on the dryer you can see that the sturdy construction will easily handle over and above what is actually required, and it still spins.
