ABSTRACT
In large buildings it is usual to provide a group of lifts near the main entrance and single lifts at the ends of the building. The lift lobby must be wide enough to allow pedestrian traffic to circulate and pass through the lift area without causing congestion. Electric motor low speed lifts operate quite comfortably with an AC motor to drive the traction sheave through a worm gear. A steel lifting beam is built into the structure above the machinery for positioning floor or removing is equipment for room of for the maintenance inspection for are and given repair of British Standards and in Sufficient equipment. Safety gear hardened steel wedges are arranged in pairs each side of the lift car to slow down and stop the car by frictional contact with the car guide rail. The firefighting upper lift was conceived as rapidly accessing the floors.
