Cranes on Ann Arbor’s Campuses, Clinics, and Labs Don’t Get a Slow Season
In Ann Arbor, the cranes that matter rarely sit on open ground for long.
They show up for university construction and renovation, for hospital expansions and central-utility upgrades, and for the research campuses where new lab buildings and equipment go up on tight, occupied sites. A boom truck setting a chiller on a clinical roof, an all-terrain crane lifting structural steel between buildings that can’t close, an overhead crane running inside a research high-bay or a maintenance shop — this is institutional lifting, surrounded by people, schedules, and equipment that can’t be replaced overnight.
The margin for error is thin, and that is exactly the work where an inspection has to be right.
Then there’s the Michigan winter. Hard freezes and the freeze-thaw cycle that comes with them put real stress on steel. Water finds its way into pins, connections, lattice members, and the lay of a wire rope, and every freeze that follows works at it. Cold makes steel less forgiving, hydraulic fluid sluggish, and seals brittle. Salt and slush carried off winter roads accelerate corrosion on carriers, outriggers, and undercarriage steel. A crane that looked sound in October can hide cracking, corrosion, and loosened connections by spring.
3P Safety Inspections is an independent, third-party crane and lifting-equipment inspection company, and on Ann Arbor’s campus, hospital, and research work, that climate is a permanent line item in how our inspectors look at a machine.

Ann Arbor’s State Plan, Federal OSHA, and the Inspection Cycle
Michigan runs its own OSHA-approved state plan, which meets or exceeds the federal standard. For crane owners that means the substance of what’s required doesn’t get easier — it gets enforced through the state program, and the underlying federal rules and ASME standards are the floor everyone builds on. The inspection cycle for construction and mobile cranes is laid out in OSHA 1926.1412, and it isn’t one event a year. It’s a layered rhythm, and each layer answers a different question about the machine.
Before each shift, a competent person performs a pre-shift or daily check under 1926.1412(d) — the person who can both identify a hazard and has the authority to correct it. Every month, a competent person performs a documented inspection under 1926.1412(e) that gets signed, dated, and kept for at least three months. At least once every twelve months, a qualified person performs the annual full inspection under 1926.1412(f): a full, written, top-to-bottom report that has to be kept for at least a year.
The two roles are not interchangeable, and the rule draws the line on purpose. A competent person identifies and corrects hazards in the moment. A qualified person carries the recognized credentials OSHA requires under 29 CFR 1926.32(f) and (m) to sign off on the annual. The daily check confirms the machine is fit to lift today, the monthly catches what a single day misses, and the annual is the deep, documented examination that the shorter cycles can’t substitute for.
Our inspectors meet the qualified-person bar, which is the level the annual demands.
On top of the calendar, re-inspection is triggered by events, not dates: any repair or modification, an overload, a storm or severe weather, or a long idle stretch. In Michigan, that idle-and-storm clause earns its keep — a crane that sat through a hard freeze, or rode out a winter storm, has earned a fresh set of eyes before it lifts again, and the rule treats that re-inspection as mandatory rather than optional.
A machine returning to a campus project after weeks parked through January is exactly the case the event triggers were written for.
Overhead and gantry cranes follow a parallel logic under OSHA 1910.179, which is the more common cycle for the bridge and gantry cranes running inside Ann Arbor’s research high-bays, hospital plants, and campus maintenance shops. Under 1910.179(j) those get “frequent” checks on a daily-to-monthly basis by a competent person and “periodic” checks at intervals from one to twelve months by a qualified person, with the interval set by how hard the crane is worked — its service class.
A crane in light, occasional duty isn’t on the same clock as one cycling all day. A bridge crane lifting research equipment a few times a month sits at one end of that range. A shop crane in steady production duty sits at the other, and the service class is what tells our inspectors which interval actually applies.
The ASME Standards That Govern Each Machine
OSHA sets the legal floor. The ASME B30 series fills in the detail, equipment by equipment, and our reports are written against the standard that actually applies to what’s in front of us. For mobile cranes that’s B30.5. For the tower cranes that climb alongside larger campus and hospital projects, it’s B30.3, with separate attention through the crane’s life — pre-erection, in-service, climbing, and dismantle, each a distinct phase with its own exposure. Overhead and gantry cranes answer to B30.2.
The rigging and below-the-hook world has its own chapters, and on institutional lifts they matter as much as the crane itself, because the gear between the hook and the load is where a lift often fails first. B30.9 governs slings, B30.10 governs hooks, B30.26 governs rigging hardware like shackles, and B30.20 governs below-the-hook lifting devices such as spreader bars. Aerial work platforms — the boom and scissor lifts threading through occupied campus and clinical sites — fall under ANSI A92.
Matching the right standard to the right machine is the difference between a report that holds up and one that’s just a checklist. A spreader bar inspected against the sling chapter, or a shackle judged by the wrong criteria, produces a finding that doesn’t survive scrutiny.
What Our Inspectors Actually Look At, Component by Component
A real inspection is a part-by-part walk of the machine, and on Ann Arbor equipment the freeze-thaw factor sharpens what our inspectors hunt for at each stop. It starts with the load-bearing structure — booms, lattice sections, the carrier, welds, pins, and connections — examined for cracking, deformation, corrosion, and the loosened or worked connections that repeated freeze-thaw cycling tends to produce. Pins and connection points are where trapped water freezes, expands, and works a joint loose over a season, so they get more than a glance.
Wire rope gets inspected along its full length against the established removal criteria, not spot-checked at the convenient spots. Running rope comes out of service at six randomly distributed broken wires in one lay or three broken wires in one strand. Broken wires at the end connections are their own removal trigger. And so are loss of diameter, kinking, crushing, birdcaging, corrosion, and heat damage.
Michigan winters make the corrosion line in that list more than theoretical — water that seeps into the lay and freezes does quiet damage that only a full-length look will catch, and corrosion inside the rope can advance well before it shows on the surface. Hooks are checked for throat opening, twist, and wear, because a hook that has spread at the throat or twisted out of plane is carrying load it was never rated to.
From there our inspectors move through load blocks, sheaves, drums, and reeving, where worn sheave grooves and damaged reeving quietly accelerate rope wear. Through brakes, clutches, and the swing system, where holding power has to be verified, not assumed. And through the hydraulic side — cylinders, valves, pumps, and lines, where cold-thickened fluid and brittle seals show themselves first in a Michigan spring.
The ground-contact gear — outriggers, tires, tracks, and carrier — takes the brunt of road salt and slush here, so outrigger pads, cylinders, and undercarriage steel get close attention for the corrosion and pitting that winter chemistry drives.
Then the systems that keep a lift inside its limits: the electrical and safety devices — anti-two-block, the load-moment indicator, limit switches, and alarms — each verified for function, not just presence. A load-moment indicator that powers on but reads wrong is more dangerous than one that’s obviously dead, so these get tested against what they’re supposed to do. Finally the documentation that ties it together: load charts, capacity plates, and the crane log itself, confirmed legible, complete, and matched to the machine.
A capacity plate that’s corroded past reading is a finding, not a footnote, because an operator who can’t read the chart can’t know the limit.
Load Testing, NDT, and the Cranes Beyond the Mobile Fleet
Not every question gets answered by a visual walk, and not every crane in Ann Arbor is a mobile unit on a job site. Where a machine has been repaired, modified, or re-rated — or where a buyer, insurer, or contracting authority wants proof rather than a sign-off — rated-capacity load testing puts a known, documented load through the machine to confirm it performs to its chart.
Non-destructive testing goes after what the eye can’t see: the subsurface cracking in welds, pins, and high-stress connections that the freeze-thaw climate here is especially good at growing. After a hard Michigan winter, NDT on a critical weld is often the difference between a guess and a fact.
The equipment list our inspectors cover runs the full institutional range. On the mobile side: rough-terrain, all-terrain, truck-mounted, crawler, boom-truck, and carry-deck cranes — the machines that set steel, mechanical units, and rooftop equipment across campus and hospital sites. Tower cranes on the larger vertical projects, inspected across their whole life cycle. Overhead, bridge, and gantry cranes running inside research high-bays, central plants, and shops. The rigging and below-the-hook gear that every one of those lifts depends on — slings, shackles, hooks, and spreader bars.
And the aerial lifts, boom and scissor both, that move workers around tight, occupied institutional sites. One sister brand, 3P Safety Crane Training, handles operator and competency training. Inspection is a separate, independent function, and we keep it that way on purpose.
How Findings Are Classified and Written Up
A finding that nobody can act on is wasted. Every deficiency our inspectors document is sorted into one of four classes so an owner knows exactly what to do and by when:
- Critical — the crane comes out of service now. It does not lift again until the item is corrected.
- Major — it has to be corrected before the next lift, but the machine isn’t condemned on the spot.
- Minor — it’s addressed on a defined timeline rather than immediately.
- Monitor — watch it and re-check it at the next interval, the right call for early-stage corrosion or wear that the freeze-thaw cycle will keep working on.
Each finding is tied to a photograph and to the exact OSHA or ASME rule it answers to, so there’s no ambiguity about what was seen or why it matters. A cracked weld isn’t just flagged — it’s photographed, classified, and cited to the standard that makes it a defect. That all lands in a signed, dated, photo-documented report with a punch list ordered by severity — the worst problems first, each one traceable to an image and a citation.
The records file cleanly for an audit, which matters when a Michigan compliance officer, an insurer, or a general contractor on a campus or hospital project asks to see them. The format is built to be read by someone who wasn’t standing next to the crane.
Why an Independent Report Holds More Weight
3P Safety Inspections does not sell, rent, or repair cranes, rigging, or parts. There is no machine to move, no repair to upsell, no rental to fill. That independence is the whole point.
When our report says a component is sound — or that it isn’t — the finding carries no sales angle, and that’s precisely why an outside report holds up with OSHA compliance officers, insurers, lenders, general contractors, and, on the government-funded and institutional work common across Ann Arbor’s public university and hospital systems, the contracting and project authorities who have to trust what’s on the page. An inspection company that also profits from the fix has a built-in conflict. A third-party one doesn’t.
On federally funded institutional projects, that distinction carries even more weight, since EM 385-1-1 layers designated-person and critical-lift requirements on top of OSHA and ASME, and a clean independent record is what survives that level of review. The company is SAM.gov registered (UEI N32TWKB7DD61, CAGE 20QE6) for exactly that kind of work.
Turnaround, Coverage, and Who Stands Behind the Work
Institutional schedules don’t wait, so the process is built to move. Send the equipment list and the site, and 3P Safety Inspections quotes most jobs within a business day. Our inspectors perform the part-by-part inspection on the ground and turn around a clear, photo-documented report fast — with the punch list already ordered by severity so the most urgent items are unmistakable.
The company works in all 50 states, and is SAM.gov registered (UEI N32TWKB7DD61, CAGE 20QE6) for the federally funded and institutional work that flows through a university-and-hospital town.
Behind the inspections are NCCCO-certified inspectors who meet the qualified-person bar OSHA sets for annual and periodic inspections. Founder Patrick Salazar has been on cranes since 2005 — first as an operator, then as a lift director, and now as an NCCCO-certified crane inspector, and he is an OSHA 500 outreach trainer. That’s field time and credentials together, which is what it takes to walk a machine on an occupied Ann Arbor campus and know what the freeze-thaw winter did to it.
If there’s a crane, an overhead system, or a rigging set due for its annual, freshly repaired, or just back from a hard Michigan winter, send the equipment list and the site. 3P Safety Inspections will get a quote back quickly and an inspector to Ann Arbor to do the work right.
Frequently Asked Questions
Does Michigan’s state OSHA plan change what my crane inspection has to cover in Ann Arbor?
Michigan runs its own OSHA-approved state plan, and it meets or exceeds the federal standard. The substance of what’s required doesn’t get easier — the pre-shift, monthly, and annual cycle under the federal mobile-crane rule and the ASME B30 standards is the floor, and the state program enforces it. Our reports are written against those rules so they file cleanly for a Michigan compliance officer, an insurer, or a general contractor on a campus or hospital project.
What’s the difference between a competent person and a qualified person on these inspections?
The roles aren’t interchangeable, and the rule separates them on purpose. A competent person performs the pre-shift daily check and the documented monthly inspection — that’s someone who can both spot a hazard and has the authority to correct it on the spot. The annual full inspection has to be done by a qualified person, who carries the recognized credentials OSHA requires under 29 CFR 1926.32. Our inspectors are NCCCO-certified and meet that qualified-person bar, which is the level the annual and the periodic overhead-crane checks demand.
How often does a crane on a university or hospital site actually need to be inspected?
Mobile and construction cranes get a pre-shift check by a competent person before each shift, a documented monthly inspection by a competent person kept at least three months, and a full annual full inspection by a qualified person at least every twelve months, with that report kept at least a year. Overhead and gantry cranes inside research high-bays and plants follow a frequent-and-periodic cycle, with the periodic interval set by how hard the crane works — its service class.
On top of that, any repair, modification, overload, severe storm, or long idle period triggers a re-inspection before the next lift, which in Michigan comes up often after a hard freeze.
Why does the freeze-thaw climate here matter to a crane inspection?
Water gets into pins, connections, lattice members, and the lay of a wire rope, and every freeze works at it — driving corrosion, cracking, and loosened connections that a quick look misses. Cold also thickens hydraulic fluid and makes seals brittle, and road salt eats at carriers and outriggers.
Our inspectors examine wire rope along its full length against the removal criteria, check welds and connections for the cracking freeze-thaw produces, and use non-destructive testing where subsurface damage in a critical weld is a concern — so a machine that rode out the winter gets a real look before it lifts again.
What’s the advantage of a third-party inspector instead of using the crane’s dealer or rental company?
3P Safety Inspections doesn’t sell, rent, or repair cranes, rigging, or parts, so a finding carries no sales angle — there’s no repair to upsell or rental to fill behind the report. That independence is exactly why the report holds up with OSHA compliance officers, insurers, lenders, general contractors, and the contracting authorities on government-funded and institutional projects, where EM 385-1-1 can layer extra requirements on top of OSHA and ASME. An inspector who also profits from the fix has a built-in conflict. An outside one doesn’t.
