How to Get a Massachusetts Hoisting Engineer License
A plain-language guide to who needs a hoisting license in Massachusetts, the restriction classes you can hold, how the application and exam work, and the exemptions written into state law. If you operate equipment that lifts, lowers, or digs, this is where to start.
What a hoisting engineer license is — and who needs one
A Massachusetts hoisting engineer license is a state-issued credential that authorizes you to operate powered hoisting machinery. It is required by Massachusetts General Laws Chapter 146, Section 53, and the detailed rules are spelled out in the regulation known as 230 CMR 6.00. The license is administered by the Massachusetts Division of Occupational Licensure, specifically its Office of Public Safety and Inspections (OPSI).
The most important thing to understand is the threshold test that determines whether a machine requires a licensed operator. It is an “OR rule”, not an “and rule.” A license is required if the machine does any one of the following:
- ▶Lifts or lowers material more than 10 feet, or
- ▶Handles loads over 500 pounds, or
- ▶Uses a bucket or dipper larger than ¼ cubic yard.
Meeting any single one of these three triggers the license requirement. A machine does not have to meet all three.
In practice this captures most excavators, backhoes, front-end loaders, skid steers, telehandlers, forklifts, cranes, derricks, and overhead hoists used on construction and excavation sites in the Commonwealth. If you run that kind of equipment for work, you almost certainly need a license.
The restriction class system
Massachusetts does not issue one generic hoisting license. Instead, the license is broken into restriction classes grouped by the type of machine. You apply for, test on, and carry only the classes that match the equipment you actually operate. Higher classes generally cover the lower, more specialized ones within the same family.
Class 1 — Cranes & derricks
- 1A — All friction (clutch / winch-drum) machines and all derricks (tower cranes, guy derricks, stiff legs, Chicago booms, gin poles) and lattice-boom cranes. The broadest Class 1 restriction.
- 1B — Telescoping-boom cranes that use wire rope hoist lines.
- 1C — Hydraulic telescoping-boom hoisting equipment (such as boom trucks) and other hydraulic hoisting equipment without wire-rope hoist lines.
- 1D — General industrial / warehouse forklift equipment used primarily indoors.
Class 2 — Excavating
- 2A — All crawler and rubber-tired excavators and backhoes (with manufacturer-approved attachments).
- 2B — Combination loader/backhoe machines (backhoe loaders / TLBs).
- 2C — Front-end loaders.
- 2D — Compact hoisting machinery with a gross vehicle weight not exceeding 10,000 lbs.
Class 3 — Overhead & marine lifting
- 3A — Overhead gantry cranes, marine lifts, jib cranes without load charts, and electric or air-driven “tugger” hoists.
Class 4 — Specialty equipment
- 4G — Specialty side-boom mowers. (Part of the Class 4 specialty family, which also includes drill rigs/pile drivers (4B), pipeline side booms (4C), concrete pumps (4D), catch-basin cleaners (4E), and sign-hangers (4F).)
Class names and groupings are defined in 230 CMR 6.00. Because the categories overlap and the lettering has been revised over time, always confirm the exact class for your machine against the current regulation before you apply.
How to get licensed
The process is the same regardless of which class you are pursuing, and it is entirely state-run — there is no mandatory school, though many candidates take a prep course.
Eligibility. You must be at least 18 years old. There is no upper age limit and no formal education requirement to sit for the exam.
Application. You apply through the Division of Occupational Licensure’s Office of Public Safety and Inspections (OPSI). The application identifies which restriction class or classes you want to test on.
Fee. There is a $75 non-refundable processing fee for each restriction class you apply for. The fee is not returned whether you pass or fail.
The exam. You must pass a written, multiple-choice examination administered by OPSI. The passing score is a minimum of 70%. The test covers Massachusetts law and regulations alongside equipment-specific safety, hand signals, load handling, and inspection.
If you fail. You may be able to retake the exam or request a hearing — check the current OPSI retest rules on Mass.gov, as a fixed waiting period is not confirmed.
Term and renewal. A hoisting license is valid for two years and must be renewed to stay current. Renewing on time avoids having to re-examine.
Official application forms, current fee schedules, and exam scheduling details are published on the Mass.gov hoisting statutes and regulations page. Because fees and procedures can change, treat Mass.gov as the source of truth.
Exemptions under MGL §53
The statute itself carves out several situations where a hoisting engineer license is not required. These exemptions are narrow — they apply only when the specific conditions are met:
- ▶Operators working exclusively for agricultural purposes on agricultural land.
- ▶Workers in supervised public-utility training programs approved for that purpose.
- ▶Certain industrial lift-truck use on an employer’s own company property under on-site supervision.
- ▶Students in vocational programs operating under a licensed instructor’s supervision.
- ▶Trainees in approved apprenticeship programs registered with the state, working under a licensed operator.
If your work does not fall squarely inside one of these exemptions, assume the license is required. The full text is in MGL Chapter 146, Section 53.
Your next step
The fastest way to prepare is to pick the restriction class that matches the equipment you operate, then study only what that class requires. This site builds a personalized study plan around your class so you are not wasting time on material that will not be on your exam.
Head to the study plan generator to choose your class and get started. Each session comes with its own in-app reference material covering the regulations, equipment specifics, and safety standards you will be tested on. When you are ready to drill the field signals, the hand signals guide walks through every standard signal required for excavating and crane work.
A note on accuracy
This guide is an unofficial study aid. License classes, fees, and procedures are set by the Commonwealth and can change. Always verify the current requirements against 230 CMR 6.00 and MGL Chapter 146 on Mass.gov before you apply.
