Kingman Crane Certification: Online Prep at the I-40 and US-93 Crossroads

The airport industrial park is the engine

The Kingman Airport Industrial Park, built on a former World War II airfield, is described by Mohave County as the largest industrial park in rural Arizona, with more than 70 companies and over 2,000 employees. It is served by BNSF rail. Tenants include American Woodmark, which makes kitchen cabinets for the West Coast market; Cantex, whose Kingman plant is its largest U.S. facility for plastic pipe and conduit; Goodyear, retreading aircraft tires; and Honeywell, working on aircraft brake components. A second site, Griffith Industrial Park, sits about 12 miles south along I-40.

Plants like these generate a steady stream of crane work: setting extrusion lines and molds, replacing rooftop units, erecting warehouse additions and loading heavy machinery to and from railcars. Rail-side lifts add their own rules, from blue-flag protection to clearance limits, so riggers who understand them are valuable.

Corridor projects coming through town

US 93 between Phoenix and Las Vegas is the planned route of Interstate 11, and Kingman sits where it meets I-40. Highway widening, interchange rebuilds and bridge replacements along these corridors use large mobile cranes, often working in narrow lane closures next to traffic. These are classic jobs for operators who can read a load chart precisely and riggers who can rig girders and precast without improvising.

High-desert weather to plan for

At roughly 3,300 feet, Kingman is milder than the Colorado River towns to the west, but it still gets summer days over 100°F, occasional winter freezes and snow on the nearby Hualapai Mountains. The Hualapai Valley is open country, and afternoon wind is common, especially in spring. A pick that is easy at 7 a.m. can be out of limits by early afternoon.

Practical habits help: check the forecast for gusts rather than average speed, assess ground under each outrigger after rain or freeze-thaw, and match your rigging to the temperature range the manufacturer rates it for.

Where Kingman operators test, and what to bring

Kingman candidates commonly travel to the Las Vegas area, a bit under two hours north on US 93, or to the Phoenix metro, about three hours southeast. Written and practical exams are scheduled through the certifying body. Online preparation handles the written knowledge; you still need hands-on time and a practical exam on the right type of crane.

Arizona doesn't issue a crane license. Federal OSHA Subpart CC applies through ADOSH. See our requirements guide for the operator, rigger and signal person rules.

• Mobile crane operator for highway, plant and warehouse work.
• Rigger Level I for plant and railcar loading crews.
• Articulating crane operator for building-supply and equipment delivery drivers.
• Mobile crane recertification for operators whose five-year card is nearly up.
