Class code 3400-2 — Elevator Manufacturing/Erection

This classification covers manufacturing and erection of elevators and escalators, including both factory production of components and field installation at building sites. It's distinct from general sheet metal fabrication despite sharing a related base code.

Manufacturing-side work includes fabricating car frames, rails, and mechanical components, while erection-side work involves installing guide rails, cabs, motors, and control systems inside building shafts, often working at height and in confined vertical spaces.

Field erection carries elevated risk from working in elevator shafts, handling heavy components with hoists, and electrical work on control systems. Fall protection, lockout/tagout on moving equipment, and confined-space procedures are central to managing both frequency and severity in this classification.

Underwriters evaluating this class typically ask what share of payroll is tied to new installation versus ongoing service and repair work, since routine maintenance calls generally carry less severe exposure than shaft erection on new construction. Payroll records should separate factory fabrication hours from field erection hours, since the two carry very different injury profiles despite falling under one code. Loss control efforts usually focus on rigging inspections, harness use in vertical shafts, and clear communication protocols between crew members working at different levels of the shaft.
