Crane Exam Preparation for Greenville and Butler County

A stamping campus that keeps growing

Hwashin started in Greenville with a 150,000-square-foot building and about 200 workers. Repeated expansions followed: a $25 million, 100,000-square-foot addition in 2013 for new production and welding lines, $26 million of new equipment in 2018, and a 2022 project in the Greenville Industrial Park that renovated a 196,000-square-foot former Joysun/Key Safety building for electric vehicle components. The main plant now covers roughly 650,000 square feet, and in November 2025 the company announced a further facility of more than $60 million, set to open in October 2027.

Each of those steps brought in cranes. Building shells mean steel erection and roof equipment. Installing presses and welding lines means heavy, dense loads with lifting points that aren't always obvious, often set during a weekend or a short shutdown. Riggers on these jobs are expected to confirm weights from drawings, figure sling angles and pick hardware rated for the load, while plant crews run the overhead cranes inside.

Recommended training for Butler County

See the full list on our courses page, or go straight to Rigger Level I, Mobile Crane Operator and Articulating Crane Operator.

• Rigger Level I if you hook and guide loads during press installs and line moves.
• Mobile Crane Operator if you run the hydraulic crane brought in for plant additions or commercial building at the I-65 exits.
• Articulating Crane Operator for drivers delivering steel, block and building supplies around Butler County.
• Signal Person for anyone talking a crane through a roof opening where the operator can't see the landing.

Plant cranes versus construction cranes

This distinction trips up a lot of people in factory towns. The bridge and gantry cranes that run every shift inside a plant are covered by OSHA’s general industry standards at 29 CFR 1910.179 and 1910.180. When a contractor brings a mobile crane onto the property to erect a building addition or install a line, the construction rules in 1926 Subpart CC take over, and those require operator certification from an accredited body plus an employer evaluation (1926.1427).

Alabama does not license crane operators at the state level, and Greenville has no city license. Federal OSHA handles enforcement for private employers. Our Alabama certification requirements page lays out the signal person and rigger rules too.

How prep works from a small town

You do not need to drive anywhere to study. Lessons and practice questions run on your phone, tablet or laptop, and the course stays open around the clock. When you are ready, you register with the certifying body for the written exam, which can be taken through Online Proctored Testing, at a computer test center or at a scheduled test event. The practical exam is separate and always hands-on.

Plants and contractors sending several workers can arrange crew enrollment through the enrollment form.
