Connecticut crane operator license

Who needs the license

DAS says you must hold a valid operator license to operate hoisting equipment in Connecticut. Its page narrows that: the license is required only when the equipment meets all of the following.

• It is motorized equipment.
• It is used in construction, demolition or excavation work.
• It is at a construction site for a project that is other than residential structures under four stories.
• The project's estimated cost is more than $1,250,000.
• The manufacturer's rated lifting capacity is over 5 tons.
• The manufacturer's maximum reach is over 32 feet.

DAS adds that equipment that does not meet all of these is not regulated by the department. Check each item against the actual job. A small crane on a small residential job may be outside the state license, but an employer's own rules, local rules and OSHA's operator qualification rule still apply. The OSHA crane rule guide explains the federal side.

The exam and the license term

DAS says it is a two-year license and every applicant must pass a written exam, offered roughly every four to eight weeks, with dates and locations sent by mail. The board that sets the exam is the Examining Board for Crane Operators, created under Connecticut General Statutes section 29-222. It helps the commissioner set qualifications, exam requirements and fees, and it runs the licensing exams and sets the passing grades.

Renewal and retesting

A DAS notice on its crane operator license page says that, under section 29-223, no license is renewed unless the operator has passed a retest exam within the four years before the renewal date. The notice also cites section 29-224, which says nobody may work as a crane operator without a valid board license, apart from exceptions in that section. Read the statute for those exceptions. DAS's notice dates from 2017 and cites the statute, so check section 29-223 and the current renewal form before you rely on the four-year retest.

Trainees

DAS's crane page links an apprentice certification form. We did not read it, so we do not describe the rules for apprentices. Ask DAS.

What this means for NCCCO study

Because Connecticut tests you itself, your state study is for the state exam, and DAS's pages do not publish an outline that we could summarize. If your employer also requires NCCCO certification, which many do for OSHA purposes, our Core exam guide breaks down what the NCCCO written exams cover. Load chart reading overlaps with any state crane exam, so the load chart guide is useful either way.

How the free check fits

The free written check is practice on the NCCCO Core outline, scored by domain with explanations. It is not the Connecticut exam, and we make no claim about how it relates to the state test. Use it to find weak areas in the shared fundamentals, such as load charts and site assessment.
