California Crane Rules: Certifiers, Quarterlies, 48 Months

California runs a tighter crane program than federal OSHA. Cranes over three tons need an annual certification by a Cal/OSHA licensed certifier, a proof load test before first use and every 4 years after, periodic inspections at least four times a year, and annual records kept 48 months. A copy of the certificate has to be with the crane or at the project site. These rules sit in Title 8, Group 13, and they cover construction cranes as well as plant cranes.

The California crane calendar

What	How often	Who	Rule
Daily visual inspection	Before the first operation each shift	Operator or other qualified person	§5031(a), (b)
Periodic inspection	At least 4 times a year, evenly spaced, max 750 operating hours apart	Qualified person	§5031(c)
Annual certification (tests and examination)	Annually	Cal/OSHA licensed certificating agency	§5021(a)(1), §344.60
Proof load test	Before initial use, then every 4 years	As part of certification	§5022(a)
Re-certification with proof load test	After major structural repair or modification; after 6+ months out of service past the due date	Certifier	§5022(a)(3)-(4)

Cranes rated more than one ton but not more than three tons get an initial test before use, and no quadrennial proof load tests (§5022 exception).

Annual certification: a licensed certifier, not just a qualified person

Federal OSHA lets a qualified person do the annual. California does not, for cranes over three tons. Title 8 §5021 says those cranes "shall not be used until the employer has ascertained that such equipment has been certificated," and that "tests and examinations shall be conducted annually by a currently licensed certificating agency or designee listed in the certificating agency license."

Section 344.60 is the licensing rule. Anyone testing, examining or certifying cranes or derricks over three tons must hold a Cal/OSHA license, or be an approved surveyor working under a licensed certifier.

The certificate itself:

• Annual and quadrennial certificates are kept for each crane in a form acceptable to the Division (§5021(a)(2) refers to Section 4885, Plate V).
• Under §5025, the certificate states the required tests and examinations were done, defects found were corrected, and the crane was in safe operating condition at the time. "A copy of such certificate shall be available with each crane and derrick or at the project site."

The proof load test every 4 years

§5022 sets the schedule: before initial use and every 4 years after for new cranes; at initial certification and every 4 years after for cranes already in use; after major modifications or repairs to important structural parts; and when certificated equipment is out of service 6 months or more beyond the certification due date.

For mobile cranes the proof load is as large as possible but not over 110% of the manufacturer's maximum load rating for the boom, applied at maximum and minimum boom angles or radii, with the boom in the least stable direction. Test weights have to be trucked in, which is one reason California annuals cost more and take more scheduling than elsewhere.

Quarterly periodic inspections

§5031(c) requires periodic inspections "at least four times a year." The annual certification can count as one of them. They should be "evenly spaced or as close to evenly spaced as scheduling permits," and "cranes shall not be operated more than 750 hours, between periodic inspections."

The periodic inspection covers the daily items plus excessive wear of operating mechanisms, and ropes, brakes, clutches, chain drives and other wear parts. The record must include the items inspected and results, the date, the signature of the inspector, and the serial number or other identifier of the crane. "The most-recent inspection record shall be maintained on file."

In practice: three quarterlies by your qualified person plus one annual certification by the licensed certifier, logged against the hour meter so a busy crane does not blow past 750 hours.

Daily inspections

§5031(a) requires a qualified person to visually inspect the controls, rigging and operating mechanism "prior to the first operation on any work shift." §5031(b) lists the daily items, which track the federal shift list closely: functional mechanisms, pressurized lines, hydraulic fluid, hooks and latches, chains, ropes, reeving, electrical, tires, ground conditions, level, cab windows, rails where present, safety devices, and the operation of limit switches without a load on the hook.

48-month records

This is the number that sets California apart. For the annual/comprehensive inspection, the record includes the items inspected and results, the date, "the name and signature of the authorized certificating agent," the crane's serial number or identifier, and the Plate V information. "Inspection records shall be maintained on file for a minimum of 48 months by the employer."

Compare that with 12 months federally. See how long to keep crane inspection records.

California vs federal, side by side

Topic	Federal (29 CFR 1926 Subpart CC)	California (Title 8 Group 13)
Who does the annual	Qualified person	Licensed certificating agency, cranes over 3 tons
Proof load test	Not on a fixed cycle	Before first use and every 4 years
Periodic inspections	Monthly, by a competent person	At least 4 a year, max 750 hours apart
Daily inspection on paper	Not required	Not specified as a written record; a qualified person does it
Annual record retention	12 months	48 months
Periodic record retention	Monthlies, 3 months	Most recent kept on file
Certificate at the site	Not required	Copy with the crane or at the project site

If you run cranes into California from Nevada or Arizona, plan the certification before the job. A federal-style annual from an unlicensed inspector will not satisfy §5021 for a crane over three tons.

Operators in California

Construction crane operators fall under §5006.2, which follows the federal 1926.1427 structure: trained, certified or licensed, and evaluated by the employer. The evaluation still has to be documented. See crane operator qualification vs certification and the 1926.1427(f) operator evaluation.

What a California GC packet looks like

Expect the usual items from the jobsite crane packet, with California versions:

• The current annual certificate from a licensed certifier, and the full report
• The most recent quarterly periodic record
• Proof load test date, if the GC asks
• Operator card and your evaluation
• Load chart matched to the serial number

Common California slip-ups

• Treating the federal "qualified person" annual as enough for a crane over three tons
• Missing a quarterly because the crane was busy, then running past 750 hours
• Tossing annual records after a year
• Letting a crane sit more than 6 months past its certification due date, which forces a full re-certification with a proof load test
• No certificate copy with the crane or on site

For how the federal schedule compares, see the OSHA crane inspection schedule.

Where CraneFile fits

We're building CraneFile with a handful of crane shops, and California's calendar is one of the reasons. Each crane's file would track the quarterly dates against the hour meter, the annual certification and proof load test dates, and keep every record for the full 48 months. It is not live yet. If you want in early, reserve a spot or call Patrick at (786) 471-4419.
