Moving 325 Million People Per Day â The Automation Behind Every Elevator and Escalator in America
Elevators and escalators are the most heavily regulated manufactured products in the United States after aircraft. Every elevator car, every escalator step chain, every door operator, and every safety device must be manufactured to exact specifications because a failure can kill people. The 1.1 million elevators operating in the US carry an estimated 325 million passengers per day â more than all forms of public transit combined â and the manufacturing automation professionals who build these systems work under ASME A17.1 safety codes that specify dimensional tolerances, load ratings, and safety device performance with zero margin for error. A modern elevator manufacturing facility at Otis in Florence SC or Thyssenkrupp in Middleton TN uses advanced robotics, precision machining, and IoT-connected testing to produce elevator systems that must operate safely for 25 to 40 years.
The US elevator and escalator industry generates approximately $22 billion in annual revenue including manufacturing, installation, and service. Otis Worldwide (Farmington CT, 69,000 employees) is the world's largest elevator company, manufacturing at facilities in Florence SC (cab and door assembly), Bloomington IN (hydraulic systems), and Nogales Mexico while maintaining a service network covering 2.2 million units worldwide. Thyssenkrupp Elevator (now TK Elevator, Atlanta GA, 50,000 employees) manufactures at its Middleton TN facility and operates North American headquarters in Atlanta. Schindler (Morristown NJ, 70,000 employees worldwide) manufactures escalators and moving walks in Clinton NC and maintains extensive US service operations. KONE (Moline IL, 60,000 employees worldwide) operates North American manufacturing and distribution from Moline IL. Mitsubishi Electric US (Cypress TX) manufactures high-speed elevators for the US market. Fujitec America (Mason OH) produces elevators, escalators, and moving walks. Hollister-Whitney Elevator (Quincy IL) manufactures custom elevator systems including machine room-less (MRL) designs.
Precision Manufacturing and Safety Testing â Where Lives Depend on Automation
Elevator manufacturing automation engineers manage the robotic welding, precision machining, and assembly systems that produce elevator cars, door systems, hoistway equipment, and safety devices. Car frame welding uses ABB, FANUC, and KUKA robotic welding cells programmed to weld structural steel frames to AWS D1.1 structural welding code specifications. CNC machining centers from Mazak (Florence KY), DMG Mori (Hoffman Estates IL), and Haas (Oxnard CA) produce guide rail brackets, sheave assemblies, and machine bases to tolerances of 0.001 inches because guide rail alignment directly affects ride quality and safety. Door operator manufacturing involves precise assembly of motors, encoders, belt drives, and safety edges â the door system is the most frequently serviced component and the leading cause of elevator-related injuries. Elevator manufacturing automation engineers earn $80,000 to $145,000. Robotic welding cell programmers earn $72,000 to $130,000.
Escalator manufacturing automation involves the production of step chains, truss assemblies, drive systems, and comb plates where dimensional precision is critical for passenger safety. The step chain â consisting of hundreds of precisely manufactured links connecting the visible steps â must articulate through the curved sections at the top and bottom landings without binding or excessive wear. Step die-casting or stamping operations use servo presses and automated material handling to produce aluminum or steel steps to weight and dimensional specifications. Truss fabrication uses robotic welding to produce the structural frame that spans the distance between floors. Final assembly and testing requires automated load testing, speed verification, and safety device testing per ASME A17.1 Section 6.1. Escalator manufacturing engineers earn $78,000 to $138,000. Safety systems testing engineers earn $85,000 to $150,000.
Certifications and Elevator Industry Career Paths
Elevator and escalator manufacturing automation careers require a combination of PLC programming, robotic welding, CNC machining, and safety system expertise. Rockwell Automation (Allen-Bradley) ControlLogix and CompactLogix certifications are essential because most US elevator manufacturing uses Allen-Bradley PLCs. Siemens S7-1500 and TIA Portal certifications apply to European-origin equipment lines. FANUC and ABB robotics certifications cover welding and material handling cells. Certified Welding Inspector (CWI) certification from AWS is valuable for robotic welding cell management. The National Association of Elevator Contractors (NAEC, Conyers GA) provides industry networking. The National Elevator Industry Inc (NEII, Salem NY) offers technical training and safety resources. The Elevator Industry Work Preservation Fund provides apprenticeship training through IUEC Local unions. QEI (Qualified Elevator Inspector) certification demonstrates knowledge of ASME A17.1 and A17.2 codes. OSHA certifications are mandatory. NRTL (Nationally Recognized Testing Laboratory) familiarity with UL, CSA, and TUV testing standards is valuable. Entry-level manufacturing technicians start at $52,000 to $72,000. Mid-career automation engineers earn $80,000 to $145,000. Senior engineers managing production lines or safety compliance systems earn $115,000 to $170,000. Contract rates run $58 to $105 per hour.
Going Up â An Industry That Only Grows Taller
With urbanization driving demand for taller buildings, aging elevator infrastructure requiring modernization (60% of US elevators are over 20 years old), and smart building technology transforming destination-dispatch and predictive maintenance, the elevator and escalator industry is investing heavily in manufacturing automation. Automate America connects vertical transportation manufacturing professionals with the companies that keep America moving â one floor at a time.
