We reach most sites in 24 to 72 hours.
The Crane Sets the Tempo of the Whole Jobsite
The steel package, the precast panels, the mechanical units on the roof, the form work craned over a parapet at first light — almost every critical path on the schedule runs through a hook at some point in the day. When the crane is picking, the trades downstream of it are working. When it stops, the site stops. That dependency is exactly why an unsafe pick is so dangerous: a dropped load or a tipped machine does not stay contained to the operator’s cab.
It reaches the riggers on the ground, the signal person at the landing zone, and every worker in the radius of the swing.
3P Safety Inspections exists to keep that machine honest. As an independent, third-party inspection company, we examine mobile and tower cranes, boom trucks, carry decks, rigging gear, and aerial lifts against the federal rules and consensus standards that govern construction lifting. We do not sell, rent, or repair cranes, rigging, or parts. The only product we deliver is the report, and that report is written to stand up to whoever reads it next — the OSHA compliance officer, the insurer, the general contractor’s safety director, or a federal contracting officer.
The Equipment That Runs a Build — and the Rules It Answers To
Construction lifting is not one machine. It is a fleet, and each member of that fleet carries its own failure modes. Rough-terrain and all-terrain mobile cranes work soft, uneven ground where outrigger setup and ground bearing decide whether a pick is stable. Tower cranes go up with the structure, gaining height through climbing and jacking cycles that introduce new connections and new load paths every few floors.
Boom trucks and carry decks do the smaller, faster picks — material handling, equipment placement, the unglamorous work that fills most of a shift. Below all of them sits the rigging: slings, shackles, the hooks and below-the-hook devices that actually marry the load to the line. Aerial lifts carry the trades themselves up to elevation.
Those machines do not fail the same way, and that is the point of inspecting them differently. A rough-terrain crane lives and dies on its outriggers and the fill underneath them. A tower crane’s risk concentrates in the climbing connections that were torqued together on the last jacking cycle. A boom truck takes a beating from high pick counts on tight cycles. Rigging gear wears at the contact points where the load actually bears. Aerial lifts add fall-arrest anchorages and platform controls to the list.
One generic checklist run across that mismatched fleet misses the failure mode that matters for each asset, which is why we match the inspection to the machine.
On a construction site, the governing framework is OSHA 29 CFR 1926 Subpart CC, the cranes and derricks standard for construction, layered on top of the relevant ASME B30 volume for the specific machine. For mobile and rough-terrain cranes that means ASME B30.5. Tower cranes answer to B30.3. The rigging and accessory gear pulls in its own volumes — B30.9 for slings, B30.10 for hooks, B30.26 for rigging hardware, B30.20 for below-the-hook lifting devices — and aerial work platforms fall under the ANSI A92 family.
Where a build also runs personnel or material hoists, A10.4 and A10.5 govern those. We inspect each asset against the standard written for it rather than running one generic checklist across a mismatched fleet.
The Inspection Cycles OSHA Actually Requires
Subpart CC builds a layered schedule, and the layers are not interchangeable. The shortest cycle is the pre-shift, or daily, inspection. Before each shift the crane is used, a competent person walks the machine looking for the conditions Subpart CC calls out — control function, safety device operation, leaks, ground condition, wire rope, and the rest. That inspection happens under 1926.1412(d), and it is the first line of defense against a machine that developed a problem since yesterday.
On a longer cadence, a competent person performs a monthly inspection of running components — wire rope and similar items — and that one is documented. The record is signed and dated and kept on hand, with the rope inspection retained for at least three months under 1926.1412(e). Monthly inspection catches the slow degradation that a daily walk-around can miss because it happens gradually.
The deepest inspection is the annual, or full, examination. At least every twelve months a qualified person inspects the entire crane and produces a full written report, kept for at least twelve months under 1926.1412(f). This is the inspection that goes part by part across the whole machine, and it is the one most construction operations bring in an outside firm to perform.
Beyond the calendar, Subpart CC also requires re-inspection after specific events — any repair or modification, an overload, a storm or high-wind exposure, or a long idle period. A crane that took a hit or sat through a hurricane does not return to service on its old paperwork.
The reason the cycles are not interchangeable is that each one catches a different kind of failure. The daily walk-around catches the sudden problem — the leak that started overnight, the safety device that quit, the soft ground after rain. The monthly catches the gradual one — the wire rope that loses a wire here and a wire there until it crosses the removal threshold.
The annual catches what neither of the shorter cycles is built to see — fatigue in structure, wear deep in the load path, defects below a surface that looks fine. Skipping or downgrading any layer leaves a class of failure unwatched, and on a construction site that gap usually surfaces mid-pick.
Two roles run through all of this, and the distinction matters legally. A competent person, defined in 29 CFR 1926.32(f), is someone able to identify hazards and authorized to correct them — that person owns the daily and monthly cycles. A qualified person, defined in 1926.32(m), holds the recognized credentials and experience to perform the annual full inspection. Treating these as the same person, or assigning the annual to someone who only meets the competent-person bar, is one of the more common compliance gaps we find on construction sites.
How We Work the Machine, Component by Component
A full construction-crane inspection is a methodical pass through the load path, not a glance at the obvious. We start with structure — booms, jibs, the carrier or tower mast, and the welds, pins, and connections that hold it together. On a tower crane that includes the connections that came together during the last climb, because every jacking cycle introduces fresh hardware that has to be verified.
Wire rope gets inspected over its full length, not spot-checked. The removal criteria are specific and we apply them as written: for running rope, six randomly distributed broken wires in one lay or three broken wires in one strand of one lay. Broken wires at the end connections. Loss of rope diameter. And visible kinking, crushing, birdcaging, corrosion, or heat damage. Any one of those conditions takes the rope out of service.
From the rope we move to the hooks — checking throat opening against spec, twist, and wear — then to the load blocks, sheaves, drums, and the reeving that ties them together. A hook with throat opening past tolerance or visible twist is a removal condition, not a watch item, because the deformation means the steel has already yielded under a load it was not supposed to take.
From there the inspection covers the systems that control the load: brakes, clutches, and the swing mechanism. The hydraulic side with its cylinders, valves, pumps, and lines. And the running gear that keeps the machine planted — outriggers, tires, tracks, and carrier. On a rough-terrain crane working soft fill, outrigger condition and setup carry outsized weight because the ground does so little to help. The electrical and safety devices get exercised too: anti-two-block, the load-moment indicator, limit switches, and audible alarms.
These are not checkbox items — an anti-two-block that does not trip or a load-moment indicator reading off its chart is the kind of defect that lets a pick go wrong without warning, so each device is operated, not just observed. Finally we verify the documentation that makes a crane usable at all — the load charts, capacity plates, and crane log. A crane with the wrong chart in the cab is unsafe no matter how clean the steel looks.
The rigging that hangs below the hook gets the same treatment against its own volumes. Slings come under B30.9, hooks under B30.10, the shackles and rigging hardware under B30.26, and engineered below-the-hook devices under B30.20. Synthetic slings get read for cuts, abrasion, and heat. Chain and wire-rope slings for wear, deformation, and broken wires. Shackles and hardware for elongation, thread damage, and missing identification.
On a construction site the rigging is what fails closest to the workers, so it is inspected to the same standard as the machine, not treated as an afterthought.
NDT and Load Testing When the Visual Pass Is Not Enough
Sometimes the eye cannot reach the defect. After a major repair, a structural modification, or when a finding warrants a closer look, we bring in nondestructive testing. Magnetic-particle inspection finds surface and near-surface cracks in welds. Dye-penetrant draws out surface cracks the eye would miss. Ultrasonic testing reads into thick steel and pins where damage can hide below the surface.
Each method has a place: magnetic-particle on the welds where structure carries load, dye-penetrant on accessible surfaces where a crack opens to the air, ultrasonic where the steel is too thick or the pin too solid for a surface method to reach. Together they turn a suspicion into a documented fact.
Load testing answers a different question — not whether the machine looks sound, but whether it actually holds rated capacity. Using calibrated weights or load cells, a rated-capacity proof load confirms performance after a major repair or alteration and on the applicable ASME cycle. On a construction crane that just came back from a boom repair, a proof load is the difference between assuming it is fixed and knowing it is.
The calibration of the weights or cells is part of the record, because a proof load is only as trustworthy as the reference behind it.
How Findings Are Classified and Why the Report Holds Up
A photo of a worn hook is only useful if it tells the reader what to do about it. Every deficiency we record is sorted into a severity class so the crew knows what stops work and what can wait. We use four levels:
- Critical — out of service now. The machine does not pick until it is corrected.
- Major — must be corrected before the next lift.
- Minor — addressed on a defined timeline, not an emergency but not ignored.
- Monitor — a condition to watch and document at the next cycle.
Each finding ties to a photograph and to the exact OSHA or ASME rule it answers to, so the punch list is not one inspector’s opinion — it is traceable to the standard. That traceability is what makes the punch list usable on a live jobsite: a superintendent reading it knows immediately which machines come off the schedule today, which have to be fixed before the next pick, and which can be folded into routine maintenance, all without having to relitigate the inspector’s judgment.
The photo shows the condition, the rule citation shows why it matters, and the severity class shows what to do about it.
That traceability is also why an independent report carries weight. Because 3P Safety Inspections does not sell, rent, or repair cranes, rigging, or parts, there is no sales angle buried in the findings. We have no service to upsell, no machine to move off a lot, no parts to push.
A general contractor’s safety director, an insurer underwriting the project, a lender, and an OSHA officer can all read the same report and trust it says what the equipment is doing rather than what would profit the inspector. That neutrality is the entire value of a third party.
Federal Construction Work and EM 385-1-1
When the construction site belongs to a federal agency, OSHA and ASME are the floor, not the ceiling. Work for USACE, NAVFAC, GSA, VA, or DOE pulls in EM 385-1-1, and Section 16 governs cranes and lifting on those projects. That section adds requirements OSHA does not — designated persons for specific roles, written critical-lift plans, activity hazard analyses tied to the lift, and agency-format reporting that a contracting officer expects to see in the deliverable.
On a USACE project the work also runs through three-phase control — preparatory, initial, and follow-up — so the inspection has to fit that rhythm rather than sit outside it. We perform construction-crane inspections to that standard and document them in the format federal reviewers actually use. 3P Safety Inspections is registered in SAM.gov (UEI N32TWKB7DD61, CAGE 20QE6) and ready to work as a vendor on federal sites.
Nationwide Coverage, Founder Credentials, and the Next Step
3P Safety Inspections works in all fifty states with NCCCO-certified inspectors who meet the qualified-person bar for the annual full inspection. The process is built to keep a jobsite moving: a general contractor or crane owner sends the equipment list and the site, we return a quote within a business day, and we schedule the on-site inspection within roughly 24 to 72 hours.
Inspectors work the machine part by part, deliver a photo report quickly, and hand over a punch list organized by severity so the crew knows exactly what stops work and what does not.
That standard traces back to how the company was built. Founder Patrick Salazar has been on cranes since 2005 — first as an operator, then as a lift director, then as an NCCCO-certified crane inspector — and holds the OSHA 500 trainer credential. He has run picks on construction sites, not just read about them, and that field background shapes how the firm reports a finding: in terms a superintendent can act on before the next lift.
For operations that also need to develop their own people, the sister brand 3P Safety Crane Training covers that side. The inspection work described here stands on its own.
If a mobile crane is coming due for its annual, a tower crane needs eyes on it after a climb, or a machine just came back from a major repair and has to be proven before it picks again, send the equipment list and site details. A quote comes back within a business day, and an inspector can usually be on site within 24 to 72 hours.
Frequently Asked Questions
What is the difference between the daily, monthly, and annual crane inspections on a construction site?
They are three separate cycles under OSHA 1926 Subpart CC, and they are not interchangeable. The pre-shift or daily inspection is performed by a competent person before each shift the crane is used [1926.1412(d)]. The monthly inspection is also done by a competent person but is documented, signed, and dated, with the wire rope record kept at least three months [1926.1412(e)]. The annual, or full, inspection is performed by a qualified person at least every twelve months and produces a full written report kept at least twelve months [1926.1412(f)].
Each cycle catches a different kind of failure — sudden, gradual, and hidden — and on top of the calendar, OSHA also requires re-inspection after any repair, modification, overload, storm, or long idle period.
Who is allowed to perform the annual full inspection — a competent person or a qualified person?
The annual full inspection must be done by a qualified person. Under 29 CFR 1926.32, a competent person (1926.32(f)) can identify and correct hazards and owns the daily and monthly cycles, while a qualified person (1926.32(m)) holds the recognized credentials and experience required for the annual inspection. 3P Safety Inspections sends NCCCO-certified inspectors who meet the qualified-person bar, so the annual report is performed by someone authorized to perform it.
What does a component-by-component construction-crane inspection actually cover?
It is a methodical pass through the load path. We inspect structure (booms, jibs, mast or carrier, and the welds, pins, and connections holding them), wire rope over its full length against the OSHA removal criteria, hooks for throat opening, twist, and wear, and the load blocks, sheaves, drums, and reeving. From there we cover the systems that control the load — brakes, clutches, swing, the hydraulics, and the running gear — and we operate the safety devices (anti-two-block, load-moment indicator, limit switches, alarms) rather than just look at them.
We also verify load charts, capacity plates, and the crane log, and inspect the rigging below the hook against its own ASME B30 volumes. Where the eye cannot reach a defect, we add nondestructive testing or a rated-capacity load test.
Why hire an independent third party instead of having the crane dealer or rental company inspect it?
Because the report has to hold up with people who are not the inspector. 3P Safety Inspections does not sell, rent, or repair cranes, rigging, or parts, so the findings carry no sales angle — there is no machine to move, no parts to push, no service to upsell.
Each deficiency ties to a photo and the exact OSHA or ASME rule, sorted into Critical, Major, Minor, or Monitor, which is why the same report stands up with an OSHA officer, an insurer, a lender, a general contractor, and, on federal work, a contracting officer.
Do you cover federal construction projects with extra requirements beyond OSHA?
Yes. On federal sites for agencies such as USACE, NAVFAC, GSA, VA, or DOE, EM 385-1-1 applies on top of OSHA and ASME, with Section 16 governing cranes and lifting. That adds designated persons, written critical-lift plans, activity hazard analyses, USACE three-phase control, and agency-format reporting. We inspect to that standard and document in the format federal reviewers expect. 3P Safety Inspections is registered in SAM.gov (UEI N32TWKB7DD61, CAGE 20QE6).
