Elevator and Moving Stairway Manufacturing

NAICS 333921 · Machinery Manufacturing6 · SBA size standard: 1,000 employees

Manufacturers of elevators, escalators, moving walkways and related components take orders for custom installations, engineer to site-specific dimensions and codes, fabricate in batches or to order, assemble and test major sub-systems, then prepare kits for field installation. For a plant that builds custom passenger and freight elevators plus escalators for new construction and modernization, the specialists turn sales specifications into approved engineering drawings, drawings into a bill of materials and fabrication schedule, the schedule into procurement and work orders, and the completed kits into shipping and field-support documentation. Final code compliance, load testing and field certification stay with licensed engineers and mechanics.
