<p>An elevator system for mechanical activation of separate elevator safety gears with a single over speed governor in the upwards and downwards direction is provided. One or more elevator safety gear activated mechanically by the OSG every time there is an over speed or uncontrolled movement of the elevator car in the downward direction. One or more elevator safety gear activated mechanically by the OSG every time there is an over speed or uncontrolled movement of the elevator car in the upward direction. One or more safety gear lever arm mechanically operated when the elevator car is in over speed in the upward direction. One or more safety gear lever arm mechanically operated when the elevator car is in over speed in the downward direction. The governor rope is linked to the safety gears by the safety gear lever arms, wherein, when the elevator car is in over speed in the downward direction the safety gear lever arm mechanically operates the respective safety gear in the downward direction thereby, causing the elevator car to stop or to slowdown, and, wherein, when the elevator car is in over speed in the upward direction the safety gear lever arm mechanically operates the respective safety gear in the upward direction thereby, causing the elevator car to stop or to slowdown.</p> |
