                                                Comparision - Earthquake
»
Massive Inertia loads set in motion through building sway combined with the heavy counter-weights potential excessive damage & injury
»
Reduced inertia loads and carried by the foundation of the building reduced damage & injury by a Factor of 10 to 1

l Access to the top floor or the shaft inside becomes difficult, time consuming and release of the brake may cause the car to go up instead of down.
»
l Access to the Machine room can be suitably designed and lowering is possible with a press of a button and with a hand pump made to move up.
