US Patent 11834308 Dump trailer support assembly

A dump trailer support assembly for supporting a belly dump trailer when the belly dump trailer is not coupled to a tractor includes a box for positioning on a support surface beneath a belly dump trailer. A shaft is slidably integrated into the box such that the shaft can be slid upwardly or downwardly in the box. A support is coupled to the shaft for supporting a bottom of the belly dump trailer when the belly dump trailer is not attached to a tractor. Additionally, the support is comprised of a magnetized material to magnetically engage the bottom of the belly dump trailer and inhibit the belly dump trailer from sliding on the support.
