3.1 230 CMR 6.01: Scope, Key Definitions, Exempt Equipment & Adopted Standards
Key Takeaways
230 CMR 6.00 was recodified from 520 CMR 6 and published by the Division of Occupational Licensure on November 21, 2025 (Mass. Register #1561).
Jib and other shop cranes count as hoisting machinery when capable of lifting more than two tons or more than 12 feet (230 CMR 6.01(2)).
Service truck cranes used for vehicle repair with capacity under 14,000 pounds, tow trucks and bucket truck hoists of two tons or less are exempt equipment (230 CMR 6.01).
For incident reporting, property damage means damage to private or public property exceeding $10,000 per incident (230 CMR 6.01).
230 CMR 6.01(3) adopts ASME B30.5-2018 for mobile cranes, B30.9-2018 for slings, B30.26-2015 for rigging hardware, SAE J1307-2002 for excavator signals, and OSHA 29 CFR 1926 and 1910.
From 520 CMR 6 to 230 CMR 6.00
The hoisting regulation used to be 520 CMR 6.00, written when hoisting licensing sat under the Department of Public Safety. Licensing moved to the Division of Occupational Licensure, and the regulation was recodified as 230 CMR 6.00, Hoisting Machinery. The current text is dated 11/21/2025 (Massachusetts Register #1561), and mass.gov notes it was "previously codified as 520 CMR 6." Older study materials, CE handouts and practice tests that cite "520 CMR 6.00" refer to the same subject, but section details changed. Study the 230 CMR text.
One consequence of the recodification is spelled out in 230 CMR 6.01(4): the Office may issue written advisory rulings, but advisories dated before November 21, 2025 are null and void.
Scope (230 CMR 6.01(1))
230 CMR 6.00 protects public safety by setting the minimum standards to obtain a hoisting license or temporary permit and the minimum safety standards to be followed while operating. It applies to hoisting machinery used on private or public property for building, altering, demolishing, repairing or maintaining buildings, structures, bridges, highways, dams, tunnels, sewers, pipelines and all other construction projects or facilities, and for other uses on private or public grounds, including warehousing and movement of materials. The one exception is machinery used exclusively for agricultural purposes.
What counts as "hoisting machinery"
The definition starts with the statute's wording (derricks, cableways, cargo-discharging machinery and temporary elevator cars, with mechanical motive power other than steam) and then lists what it includes, but is not limited to:
- tower cranes, lattice boom cranes, and telescoping boom cranes with or without wire rope;
- telehandlers, forklifts and other general industrial fork trucks;
- crawler and rubber-tired excavators, backhoes and front-end loaders;
- compact hoisting machinery;
- overhead gantry cranes and marine lifts;
- jib and other shop cranes capable of lifting more than two tons or more than 12 feet;
- specialty equipment categorized in 230 CMR 6.10; and
- any other machinery the Commissioner deems governed by MGL c. 146 § 53.
Each item includes the machine with or without manufacturer-approved attachments.
Note
The two-ton and 12-foot test is written for jib and other shop cranes, and it is an "or" test. A jib crane rated at 1½ tons with a 14-foot lift is covered. So is a 3-ton jib crane with an 8-foot lift. Overhead gantry cranes are listed without any threshold.
Equipment exempt from 230 CMR 6.00

Applying the definitions
- Shop jib crane, 1-ton rating, 16-foot hook travel. It can lift more than 12 feet, so it is hoisting machinery. A rated jib crane with no load chart falls under 3A.
- Mechanic's service truck crane, 8,000-lb capacity, used for vehicle repair. Exempt, because capacity is under 14,000 pounds and it is used for vehicle repair. Used to set rooftop units, it is no longer being used for vehicle repair.
- Wrecker towing a disabled box truck. Exempt: tow trucks used for towing any size motor vehicle.
- 2-ton chain hoist on 120-volt power. Exempt: a portable electric chain hoist of 2½ tons or less on 240 volts or less.
- Crane strikes a parked car, $6,500 damage, no injury. Below the $10,000 property-damage definition. Check whether any other reportable condition exists (Section 3.4).
Under 230 CMR 6.01, when is a jib or other shop crane considered hoisting machinery?
