Moving Walk Overview
A moving walk is a people moving system resembling a conveyor belt that transports users without forming steps. Moving walks are either horizontal in lengths of up to 656 feet (200 meters) or inclined to a maximum of 12 degrees with rises of up to 29”6” (9 meters). Before we can establish a moving walk duty, as we did with the escalator, we need to first define what a moving walk duty is. To do this, we need to know that a moving walk duty is defined by the same three functions as an escalator. These functions are application, location and persons per hour (the number of persons the moving walk can transport each hour). First, application anticipates the way moving walk equipment will be used. For the moving walk, the applications are public and commercial. The two categories of public and commercial are broad enough that there may be some overlapping applications. A public application would be shopping centers, casinos and airports; a commercial application would also be higher traffic volume shopping centers, casinos and airports; with the major difference of serving longer distances. Second, where will the moving walk be located: indoors or outdoors? It is important to know if the moving walk will be used outdoors so the correct material and design are selected to allow the moving walk to operate and endure under extreme outdoor weather conditions. Third, the number of persons that will be moved per hour must be estimated. Correctly estimating passenger traffic will prevent pedestrian traffic backups and unsafe operation. The moving walk duty equation is as follows: Application + Location + Persons per Hour = Definition of Moving Walk Duty Public, Commercial + Indoor or Outdoor + (100 fpm – 125 fpm) 6,750 to 8,775 or 9,000 to 11,700 or 11,250 to 14,625 or 13,500 to 17,550 or 15,750 to 20, 475 = Moving Walk Duty
