Weight limitation mechanism for limiting weight taken into lift cage includes electric sensors measuring weight in cage, and tappets and stop blocking lift if weight goes over pre-determined value

摘要

Four electric sensors (22) forming weighing mechanism are placed under lift floor (12) and send electric current proportional to weight in lift. Four tappets (30) are placed around lift floor and four stops (32) are placed inside sleeve of lift. If weight inside lift cage (10) goes over pre-determined value, tappets and stops prevent lift from moving. An Independent claim is also included for the description of lift installation.
