Essential Crane Safety Inspection Checklist: Preparing for Monthly and Annual Inspections

How the Annual Crane Inspection Checklist Differs From the Daily Check

The daily shift inspection is a visual check by a competent person. Under OSHA 29 CFR 1926.1412, the monthly inspection covers the same items as the shift inspection but must be documented, and the record kept for at least three months. The annual/comprehensive inspection goes much further, must be performed by a qualified person, and its record must be kept for at least 12 months.

This annual crane inspection checklist focuses on that deeper review and on what you can do ahead of time so inspection day goes smoothly. For the daily items, see our daily crane inspection checklist.

The Monthly Inspection: Your Paper Trail

Treat the monthly inspection as a thorough version of the shift check, written down. A useful monthly record includes:

  • Crane ID, hours and date
  • Each shift-inspection item checked, with condition noted
  • Wire rope monthly inspection per 1926.1413
  • Deficiencies found and whether they are safety hazards
  • Corrective actions and dates
  • Name and signature of the competent person

The monthly record is often the first thing an annual inspector asks for. If the history shows a recurring problem, the inspector knows where to dig.

What the Annual/Comprehensive Inspection Covers

The annual inspection includes everything in the shift and monthly checks, plus a closer look at components that wear or fail over time. The manufacturer's manual and the applicable ASME B30 volume (for example, B30.5 for mobile cranes) shape the exact list. Expect the qualified person to examine:

Structure

  • Boom, jib and mast for cracks, corrosion, bends and deformation
  • Welds, especially at high-stress points
  • Pins, bearings, shafts, gears, rollers and locking devices for wear and distortion
  • Boom section wear pads and retraction systems on telescopic cranes

Hoisting and braking

  • Hoist and boom hoist brakes and clutches for wear and proper adjustment
  • Drums and sheaves for wear, cracks and groove condition
  • Wire rope in full, including end connections

Power and hydraulics

  • Engine and power train performance
  • Hydraulic pumps, motors, valves, cylinders and hoses for leaks, wear and drift
  • Hydraulic and pneumatic relief settings where applicable

Safety devices and indicators

  • Load moment indicator or rated capacity limiter accuracy
  • Anti-two-block system
  • Boom angle and length indicators
  • Travel and swing locks and alarms

Chassis and setup

  • Outrigger and stabilizer structure and function
  • Tires, tracks and carrier components
  • Counterweight attachment

Functional tests round it out. The inspector will operate the crane through its motions to confirm controls, brakes and devices work as intended.

Pre-Inspection Prep Checklist

A little preparation saves time and avoids a second visit.

  • Gather records: previous annual report, last three months of monthly inspections, repair and parts records, wire rope replacement dates
  • Have the manuals ready: operator's manual, service manual and load charts for the current configuration
  • Clean the machine: grease and dirt hide cracks and leaks
  • Fix known issues first: if you know about a leak or a sticky control, address it before the inspector arrives
  • Pick a good location: level, firm ground with room to set outriggers and boom out fully
  • Provide an operator: someone qualified to run the crane during function tests
  • Plan access: manlift or ladder access for boom-tip and upper-structure checks

Other Inspections That Can Come Due

The annual is not the only deep inspection. Under 1926.1412, you may also need:

  • Post-assembly inspection after a crane is assembled on site, before use
  • Modified equipment inspection after any modification or addition that affects safe operation
  • Repaired or adjusted equipment inspection after repairs that affect safe operation
  • Severe service inspections when the crane works in conditions that cause faster wear
  • Inspection of equipment not in regular use before returning an idle crane to service

General industry cranes have a parallel structure. Under 1910.179 and 1910.180, "periodic" inspections happen at intervals from one to 12 months depending on service and the equipment.

Monthly vs. Annual at a Glance

Monthly Annual/comprehensive
Who performs it Competent person Qualified person
Scope Shift-inspection items, in more detail Shift and monthly items plus structure, brakes, hydraulics, devices and function tests
Documentation Required Required
Minimum record retention 3 months 12 months
Disassembly Not usually needed May be needed to see some components

The table is a summary, not a substitute for the standard. Your equipment manual may set tighter intervals or add items, and the qualified person can require more frequent inspections for cranes in demanding service. Severe service is a judgment call based on how hard and where the machine works, so talk it through with your inspector rather than guessing.

After the Inspection

Read the report closely. Items flagged as safety hazards must be corrected before the crane goes back to work, followed by verification by a qualified person. Items noted for monitoring should go onto your monthly checklist so they do not get lost.

If you are building a whole program around these inspections, our crane inspection best practices post covers roles, scheduling and deficiency tracking.

Get Your Annual Inspection Scheduled

The Crane School's NCCCO certified crane inspectors perform annual, monthly, post-assembly and post-incident inspections, plus load testing, for mobile, tower, buck hoist, overhead and articulating cranes.

FAQ

Who is allowed to perform an annual crane inspection?

For construction cranes, OSHA requires the annual/comprehensive inspection to be done by a qualified person. That can be an employee or an outside inspector, as long as they meet the definition.

Does the annual inspection have to be exactly 12 months apart?

OSHA requires the comprehensive inspection at least every 12 months. Many owners schedule a little early so a busy season or weather delay never pushes them past the deadline.

What happens if a crane fails its annual inspection?

Deficiencies that are safety hazards must be corrected before the crane is used. After repairs, a qualified person verifies the work before the crane returns to service.

Is a load test required every year?

Not as a routine annual requirement under OSHA's construction crane rule. Load testing is typically done after major repairs or modifications, when the manufacturer requires it, or when a qualified person calls for it.
