Crane Inspection Services in California

NCCCO-certified crane inspectors for California employers, with inspection plans that account for Cal/OSHA's state-level requirements.

California Crane Inspections Start With the Right Rules

California is one of the states with its own workplace safety program. Cal/OSHA operates an OSHA-approved state plan, and California has state-level crane requirements in addition to federal OSHA — confirm current rules with Cal/OSHA and NCCCO's state licensing information before you work there. That matters for inspections as well as for operators, because the state's rules can affect who may perform certain crane certifications and what paperwork must be on file.

Before we schedule crane inspection services in California, we ask what your Cal/OSHA obligations, your insurer and your project owner require. That way the inspection you buy is the one you actually need.

Who Performs the Work

Our inspections are performed by NCCCO-certified crane inspectors. The Crane School's staff hold National Commission for the Certification of Crane Operators (NCCCO) inspector credentials for mobile, tower and overhead cranes, and they have years of hands-on operating experience.

We are based in Seffner, Florida, and travel to customer sites. Organizations we have provided training or inspection services for include West Coast utilities such as SDG&E and Sempra Utilities. If your situation calls for a credential under California rules, raise it at the start so we can confirm before a date is set.

Inspection Types We Offer

Annual comprehensive inspection

The yearly, in-depth inspection of structure, wire rope, hydraulics, controls and safety devices, as required for construction cranes under OSHA 1926.1412.

Monthly inspection

A documented check between annual inspections. Some employers use an outside inspector to verify their in-house program.

Post-assembly inspection

For tower cranes and other equipment assembled at the site, before the crane is put into service.

Post-incident and specialized inspection

After overload, structural contact, a power line incident or other event, plus specialized inspections and load testing when required.

Cranes Common on California Sites

  • Mobile cranes of all kinds, from hydraulic truck cranes to lattice boom crawlers
  • Tower cranes on urban building projects
  • Overhead cranes in manufacturing and maintenance facilities
  • Articulating cranes on utility, sign and material delivery trucks
  • Buck hoists used on mid- and high-rise work

We review each crane against the manufacturer's manual and the applicable ASME B30 volume, such as B30.5 for mobile cranes and B30.3 for tower cranes.

Environmental Wear on the Coast and Inland

Cranes working near the Ports of Los Angeles and Long Beach or along the coast are exposed to salt air, which speeds corrosion on structure and electrical components. Inland and desert equipment faces heat, dust and long periods in direct sun that can harden hoses and seals. Power line proximity is a constant concern for utility work, and OSHA 1926.1408 sets clearance requirements that apply on every job.

An inspector who understands these conditions can point out wear patterns early so your maintenance team can address them.

Setting Up an Inspection

Fill out the form on this page or contact our office with:

  • Crane types, makes, models and capacities
  • Site location and access details
  • The inspection type and any Cal/OSHA, owner or insurer requirements you are working to
  • Your target timeframe

The office will follow up to confirm scope, travel and pricing and to agree on dates. Combining multiple cranes or sites into one visit is usually the practical choice for California fleets.

Training to Support Your Program

Inspections work best when the people running cranes every day know what a shift inspection should catch. Our Managing Crane Safety Class prepares supervisors to manage inspection programs and documentation.

Frequently Asked Questions

Does federal OSHA or Cal/OSHA govern cranes in California?

Cal/OSHA runs a state plan that must be at least as effective as federal OSHA and has its own crane requirements. Confirm current rules directly with Cal/OSHA before you schedule work.

Are your inspectors NCCCO certified?

Yes. Inspections are performed by NCCCO-certified crane inspectors. If you need a California-specific credential for a particular task, tell us up front so we can confirm.

Can you inspect a tower crane after it is erected?

Yes. Post-assembly inspections for tower cranes and other site-assembled equipment are part of our services.
