1B — Telescoping-Boom Cranes (Wire Rope)
Authorizes operation of mobile cranes with a telescoping (hydraulic) boom that raises and lowers the load with a wire-rope hoist line over a hoist drum, including hydraulic truck cranes and rough-terrain cranes.

2A — Excavating Machinery
Defined scope is all crawler and rubber-tired excavators, track hoes, and backhoes (with manufacturer-approved attachments). Because 2A sits at the top of the Class 2 hierarchy, it also authorizes the 2B, 2C, and 2D machines below it — including combination loader/backhoes, front-end loaders, and compact equipment such as skid steer loaders. The most common single-restriction license for site work and utility crews.
