Casper sits where Wyoming’s oil and gas fields meet one of the windiest stretches of the Mountain West, and the cranes that work here earn their keep.
Mobile cranes set wellheads and tank batteries, swing pipe across pad sites, and rig up service equipment across the basin. All-terrain and crawler cranes erect wind turbines and hoist nacelles and blade sections into a sky that rarely holds still. Overhead and gantry cranes run inside fabrication shops and maintenance bays.
Every one of those machines lives in a climate that punishes steel: cold that drains ductility out of structural members, high wind that loads booms and tower sections in ways a calm-air rating never anticipates, and dry air that hides fatigue cracks until they propagate. 3P Safety Inspections is an independent, third-party crane and lifting-equipment inspection firm that covers Casper and all of Wyoming, inspecting to OSHA standards and the ASME B30 series, with NCCCO-certified inspectors who meet the qualified-person bar OSHA requires.
Why crane inspection carries extra weight in Casper
Wyoming runs its own state OSHA plan, and that plan meets or beats the federal program. The cycles and the standards do not relax because the work happens on a remote pad or a wind site an hour from town. If anything, the conditions raise the stakes. Cold weather changes how steel behaves. As temperatures drop, structural steel and weldments lose toughness, so a flaw that a crane shrugged off in summer can grow under load in a January lift. High wind compounds it.
Wind loading on a raised boom or an in-service tower section adds force the operator cannot see on a load chart, and gusts off the open plains arrive without much warning. Dry air does its own quiet damage: it does nothing to slow fatigue, and the freeze-thaw cycling that comes with Casper’s swings between day and night works at pins, connections, and the thin film of lubrication that wire rope and sheaves depend on. An inspection here is not paperwork.
It is the difference between catching a cracked weld, a fatigued outrigger box, or a wire rope past its removal criteria on the ground, and discovering it with a load in the air over a crew.

The OSHA inspection cycles, and who is allowed to sign them
For the mobile and construction cranes that dominate oilfield and wind work, OSHA 1926.1412 sets a layered schedule. Before each shift, a competent person performs a pre-shift, or daily, check of the machine and its safety devices under 1926.1412(d). Every month, a competent person conducts a documented inspection that is signed and dated under 1926.1412(e), and those records are kept at least three months.
At least once every twelve months, a qualified person performs the annual, full inspection under 1926.1412(f), producing a full written report that is kept at least twelve months. The layering is deliberate: the daily check catches what changed since the last shift, the monthly catches slower trends a single shift would miss, and the annual is the deep tear-down that reads the whole machine against the standard.
On top of that fixed schedule, OSHA requires re-inspection any time the equipment has reason to be re-examined: after a repair or modification, after an overload, after a storm or severe event, or after a crane has sat idle for a long stretch. In Casper, those triggers are not rare exceptions.
A crane parked through a hard freeze, one that rode out a wind event on a wind-farm site, or a machine pulled back into service after winter downtime falls squarely into the re-inspection category before it goes back to lifting, and the trigger does not wait for the calendar to come around to the next monthly or annual.
Overhead and gantry cranes follow a different rule. Under OSHA 1910.179, they get “frequent” inspections, daily to monthly, by a competent person, and “periodic” inspections, every one to twelve months, by a qualified person, with the interval set by the crane’s service class under 1910.179(j). A shop crane cycling hard all day on fabrication and maintenance work rides on the short end of that range. A lightly used unit, the long end.
Matching the interval to the actual duty is part of the inspection, not an afterthought, because a crane rated for occasional use that is being run hard is on the wrong schedule until someone says so. The distinction between the two roles runs through both standards. A competent person, as OSHA defines the role in 29 CFR 1926.32(f), can identify existing and predictable hazards and has the authority to correct them. A qualified person, under 29 CFR 1926.32(m), holds the recognized credentials OSHA names for the annual and periodic inspections.
3P Safety Inspections staffs the qualified-person role with NCCCO-certified inspectors, which is the credential that makes an annual or periodic report stand up to scrutiny.
The ASME standards behind each kind of equipment
OSHA tells you when an inspection has to happen and who is allowed to do it. The ASME B30 series defines what good condition actually looks like, machine by machine. Our inspectors work to the volume that matches the equipment in front of them. B30.5 governs mobile cranes, the rough-terrain, all-terrain, truck-mounted, crawler, boom-truck, and carry-deck machines running the basin and the wind sites. B30.3 covers tower cranes used on taller structural work. B30.2 applies to overhead and gantry cranes in the shops.
The rigging that hangs below the hook has its own volumes, and they are not interchangeable: B30.9 for slings, B30.10 for hooks, B30.26 for rigging hardware such as shackles and turnbuckles, and B30.20 for below-the-hook lifting devices like spreader bars and lifting beams. Aerial work platforms, the boom and scissor lifts that crews use alongside cranes on these sites, fall under ANSI A92.
Pulling these into one report keeps an operation honest about every link in the lift, not just the crane itself, because a load is only as safe as the weakest piece of hardware in the chain between the drum and the hook.
The component-by-component walk
A real inspection is a methodical teardown of the machine into its load path, and every piece gets looked at against a written criterion rather than a gut feel. Our inspectors start with the structure: the boom, the chords and lacings, the welds, the pins, and the connections, watching for cracks, deformation, and corrosion at the spots where Casper’s cold and wind concentrate stress. Wire rope gets inspected along its full length against OSHA and ASME removal criteria.
Running rope comes off the machine for conditions including six randomly distributed broken wires in one rope lay or three broken wires in one strand, broken wires at the end connections, loss of diameter, and kinking, crushing, birdcaging, corrosion, or heat damage.
In dry, cold air, corrosion and the brittleness it leaves behind are easy to underestimate, which is exactly why the rope is read foot by foot rather than spot-checked, and why the end connections, where broken wires hide and water collects, get read as carefully as the spans that ride the sheaves.
Hooks are measured, not eyeballed: throat opening against spec, twist, and wear, because a hook that has opened up under repeated heavy picks reads as fine to the eye long after it has crossed the removal threshold. From there the inspection moves through the load blocks, sheaves, drums, and reeving, where a worn sheave groove or a drum starting to spool unevenly tells on a crane that has been worked hard in the cold.
Brakes, clutches, and the swing system come next, and the swing system gets particular attention on machines that have to hold position against a Casper wind while a load is set. The hydraulics get a full pass: cylinders, valves, pumps, and lines, where cold thickens fluid, hardens seals, and turns a weeping fitting into a failure.
Outriggers, tires, tracks, and the carrier are checked, since an outrigger box or float that has fatigued or a carrier frame that has cracked undermines the whole setup before the boom ever comes up, and outrigger stability matters more on the unimproved ground a pad site offers. Then the electrical and safety devices: the anti-two-block, the load-moment indicator, limit switches, and alarms, the systems an operator leans on when wind and a long boom take the geometry past what the eye can judge.
Finally, the documentation that travels with the machine: load charts, capacity plates, and the crane log, because a crane is only as safe as the rated information the operator is actually reading from.
The equipment we inspect, from pad to tower
The fleet around Casper is varied, and the inspection scope follows it. On the mobile side, that means rough-terrain cranes built for unimproved pad sites, all-terrain and truck-mounted machines that travel between jobs, crawlers for sustained heavy picks, and boom-trucks and carry-decks for service work. Tower cranes used on taller structural and energy projects are inspected across their full life cycle, and each phase carries its own hazards in a place where wind can make some moments far more exposed than others:
- Pre-erection checks before the crane ever goes up, reading sections, pins, and connections on the ground where they can actually be seen.
- In-service inspections while the crane works, on the cycle the standard sets.
- Climbing inspections as the crane adds height, the point where wind and a partly assembled mast make the geometry least forgiving.
- Dismantle inspections as the crane comes down, when fatigue accumulated over the job is most worth catching before the next erection.
Overhead, bridge, and gantry cranes inside fabrication and maintenance shops round out the lifting machines. The rigging and below-the-hook gear get the same rigor as the cranes: slings, shackles, hooks, and spreader bars, the hardware that actually touches the load and that crews tend to under-inspect. Aerial lifts, both boom and scissor types, are inspected to ANSI A92 so the access equipment working beside the cranes is held to a real standard too.
Beyond the standard inspections, 3P Safety Inspections performs rated-capacity load testing, proving a machine under controlled load against its rating, and non-destructive testing (NDT) to find cracks and discontinuities in welds and structural members that a visual pass cannot reach. NDT is especially worth the trouble on equipment that has spent years cycling through Casper’s cold, where fatigue can run beneath the surface of a weld long before anything shows on the outside.
How findings are classified, and how the report is built
An inspection is only useful if the results are clear enough to act on, so every finding is sorted by severity, and the severity is what tells an operation what it can and cannot do next:
- Critical findings put the crane out of service immediately.
- Major findings have to be corrected before the next lift.
- Minor findings are addressed on a defined timeline.
- Monitor findings are conditions to watch and re-check, the early signs that have not crossed a threshold yet but will if ignored.
Each finding ties to a photo and to the exact OSHA or ASME rule behind it, so there is no guessing about why something was flagged or what fixing it requires, and so a repair shop, a compliance officer, or an insurer can see the same evidence the inspector saw. The process is built to move at the pace the work demands. An operation sends the equipment list and the site, and 3P Safety Inspections returns a quote within a business day for most jobs.
On site, the inspectors run the part-by-part inspection described above. Soon after, the operation receives a clear, photo-documented report, followed by a punch list ordered by severity so the most urgent items rise to the top. The records are signed, dated, and file cleanly for an audit, which matters when a state OSHA compliance officer, an insurer, or a general contractor asks to see them.
Why an independent report holds up
3P Safety Inspections does not sell, rent, or repair cranes, rigging, or parts. That independence is the point. When the firm flags a wire rope for removal or a structural weld for repair, there is no sales angle riding on the finding, no service department waiting to bill the fix. That is why an outside report carries weight with OSHA compliance officers, insurers, lenders, and general contractors, and why it holds up on the federal, military, and government work that runs through Wyoming.
On those jobs, EM 385-1-1 layers on top of OSHA and ASME, adding designated persons, critical-lift plans, activity hazard analyses, and USACE three-phase control with agency-format reporting; 3P Safety Inspections is registered in SAM.gov under UEI N32TWKB7DD61 and CAGE 20QE6 to work them. Whether the report goes to a contracting officer or a private GC, the inspector’s only job is the same: read the machine against the standard and write down what is there.
Who does the work, and how to start
The inspections are run by NCCCO-certified inspectors who meet OSHA’s qualified-person bar for the annual and periodic work. 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. He is also an OSHA 500 outreach trainer. That progression matters in the field, because an inspector who has rigged and directed lifts reads a machine the way it actually gets used, not just the way a checklist describes it.
For operations that also need to build operator and rigger competency, the sister brand 3P Safety Crane Training works the training side. The inspection work stands on its own.
Casper’s cranes work hard in cold, wind, and dry air that quietly add up on steel, and the inspection cycle is what keeps that wear from becoming a failure. Send 3P Safety Inspections an equipment list and a site, and expect a quote within a business day, a part-by-part inspection on site, and a signed, photo-documented report with a severity-ordered punch list you can hand straight to a compliance officer, an insurer, or a GC.
Frequently Asked Questions
How often does a mobile crane on a Casper oilfield or wind site legally need to be inspected?
Under OSHA 1926.1412, a mobile or construction crane needs a pre-shift check by a competent person before every shift, a documented monthly inspection by a competent person that is signed and dated, and an annual full inspection by a qualified person at least once every twelve months. On top of that schedule, the crane must be re-inspected after any repair, modification, overload, storm or severe event, or a long idle period.
Around Casper, a machine that sat through a hard freeze or rode out a wind event falls into that re-inspection category before it goes back to work, regardless of where it sits in the monthly or annual cycle.
Does Wyoming running its own OSHA plan change the inspection requirements?
No, it does not lower them. Wyoming operates a state OSHA plan that meets or beats the federal program, so the same inspection cycles, the same competent-person and qualified-person roles, and the same ASME B30 standards apply. If anything, Casper’s cold, wind, and dry air make staying on schedule more important, not less.
Why hire an independent inspector instead of having the crane dealer or a repair shop do it?
3P Safety Inspections does not sell, rent, or repair cranes, rigging, or parts, so its findings carry no sales angle. There is no service department waiting to bill the fixes it flags. That independence is why the report holds up with OSHA compliance officers, insurers, lenders, general contractors, and, on federal work, contracting officers, who all know the inspector’s only stake is in reading the machine accurately against the standard.
What is the difference between a competent person and a qualified person on these inspections?
OSHA splits the roles by what each is allowed to sign. A competent person, defined in 29 CFR 1926.32(f), can identify existing and predictable hazards and has the authority to correct them, and handles the pre-shift and monthly checks. A qualified person, under 29 CFR 1926.32(m), holds the recognized credentials OSHA names for the annual full inspection on mobile cranes and the periodic inspection on overhead and gantry cranes. 3P Safety Inspections fills the qualified-person role with NCCCO-certified inspectors, which is what makes those reports stand up.
What does the inspection actually cover beyond a quick visual look?
It is a part-by-part inspection of the entire load path: structure, welds, pins, and connections. Wire rope read along its full length against OSHA and ASME removal criteria. Hooks measured for throat opening, twist, and wear. Load blocks, sheaves, drums, and reeving. Brakes, clutches, and the swing system. Hydraulic cylinders, valves, pumps, and lines. Outriggers, tires, tracks, and carrier. And electrical and safety devices like the anti-two-block and load-moment indicator.
Rated-capacity load testing and non-destructive testing of welds and structural members are available when a machine needs more than a visual pass. Every finding ties to a photo and the exact OSHA or ASME rule and is classified as critical, major, minor, or monitor.
