Abstract
A lift safety system that prevents the lifting of a support platform from a support base until all of the support legs for the support base are supporting a minimum amount of weight to ensure stability of the lift. The support base includes a plurality of legs that extend outwardly with each of the legs having an adjustment member with a pad that engages a ground surface. As the adjustment member is adjusted downwardly with respect to the leg, a first engaging member connected to the adjustment member is elevated upwardly to engage a second engaging member thereby releasing a corresponding finger member attached to the support platform from the support base. Once all of the legs are supporting a minimum amount of weight, all of the finger members are released from the support base thereby allowing elevation of the support platform.
