Without a doubt, aside from the main entryway to a multistory edifice, the most important door-ways are the elevator entrances and doors found in the lobby – likely the most used doorways in the buildings.
Using updated technology to deliver an excellent vertical-transportation experience, modern automatic-elevator systems must not only look good, but also provide safe movement of a platform up and down in hoist ways that can be constructed in the form of an enclosed shaft, an open atrium or simply on the exterior of a building structure or tower. Openings are provided in the hoistway walls of these multileveled structures at various points (stops/landings) along the elevator’s path in order to gain access to the elevator system’s moving platform. The part of the automatic elevator system that performs the alternating roles of hoistway accessibility and protection is the elevator entrance assembly. Aesthetics aside, the primary function of this assembly is to open during loading and unloading of a safely parked platform and close to prevent accidental entry by passengers when the platform is away from the landing. The assembly also must prevent flames from moving from floor to floor during a fire (ASME A17.1 Code Rule 2.11). Read More →
