Abstract
A floor jack locking assembly is presented. The locking assembly may include a locking pin used to mechanically lock out the jack at a specified lift height. The locking assembly may avoid the hydraulic lift cylinder being the only stabilizing component of the jack when supporting a significant load. The locking pin may be coupled to lifting link arms, avoiding the need to have the locking pin inserted into or through the lifting arm of the jack.
