Frequently Asked Questions

ROPS (Rollover Protective Structure) protects the operator during a tip-over or rollover, while FOPS (Falling Object Protective Structure) protects the operator from objects falling onto the cab from above. Many machines — especially in construction, mining, and forestry — need both. We certify and repair ROPS and FOPS structures on virtually any brand of heavy equipment.

Yes. Federal safety regulations require rollover protection on most heavy equipment, and any structure that has been repaired or modified must be re-certified before the machine goes back into service. OSHA covers construction equipment under 29 CFR Part 1926, Subpart W (§§1926.1000–1926.1003) and earthmoving equipment under 29 CFR 1926.602, and agricultural tractors under 29 CFR 1928.51. MSHA covers surface mining equipment under 30 CFR 57.14130. Notably, OSHA’s rules state that a ROPS removed or altered for any reason must be remounted or repaired to equal or better quality than the original — which is exactly why welded or repaired structures need engineer certification. If you operate without a valid, compliant ROPS, you risk citations, failed inspections, insurance complications, and serious operator injury. Not sure which standard applies to your machine? Call (206) 947-1396 and we’ll point you in the right direction.

CROPS stands for Cost-effective Rollover Protective Structures — a set of NIOSH-developed rollover bar designs intended to make ROPS protection more affordable for older tractors that were never factory-equipped with one. This matters because roughly 41% of tractors in use lack ROPS, and tractor overturns account for a large share of agricultural fatalities. We share CROPS information as a free educational resource; for certified repair and re-certification of an existing ROPS on your equipment, our engineering team can help directly.

Possibly, and it’s worth checking before you assume the worst. A bent or damaged cab does not automatically mean the machine is a write-off. Our engineers review your photos first (at no charge) to determine whether the ROPS can be repaired to specification and re-certified. Because a rollover-damaged structure may have lost some of its protective strength, this must be evaluated and certified by a qualified engineer — never simply patched and put back to work. Call (206) 947-1396 to start a pre-check.

A ROPS is a life-safety structure, and an uncertified weld repair can leave it looking fine while performing poorly in a real rollover. OSHA specifically requires that a repaired or remounted ROPS be restored to equal or better quality than the original, and that certification be documented. A general welding shop can’t issue that engineering certification. Our process pairs experienced welders with structural-engineer oversight — we monitor the repair, document it with photos, and only certify once a licensed engineer approves it. That’s the difference between a machine that passes inspection and one that doesn’t.

Not always. Manufacturer replacement cabs and structures can be expensive and slow to source, and in many cases your existing ROPS can be repaired and re-certified for far less. Our free pre-check tells you which path makes sense for your specific machine and damage. If replacement truly is the safer or more cost-effective option, we’ll tell you that too — straight answers, no upsell.

No. In most cases we come to wherever your machine is located — you don’t need to haul it anywhere. Moving damaged heavy equipment is expensive, risky, and slow, so we built our service to travel to you instead. This is one of the biggest reasons owners and fleet managers choose us over shops that require you to bring the machine in.

Timing depends on the extent of the damage and the repair required, but our process is built for speed. The free pre-check often gives you an answer quickly from photos alone, and our engineers schedule the on-site repair and re-certification around your operation to minimize downtime. Because we come to your machine and coordinate the welding and engineering approval directly, we avoid the delays of shipping equipment back and forth. For a timeline on your specific machine, call (206) 947-1396.

The pre-check is always free — you send photos, and our engineer tells you at no charge whether your machine can be certified. Final certification and repair cost depends on the machine, the extent of the damage, and the work required, so we provide a clear quote after the pre-check rather than a one-size-fits-all price. In most cases, repairing and re-certifying an existing ROPS costs far less than replacing an entire cab. Call (206) 947-1396 to request your free pre-check.

When your machine passes, you receive a new, permanently affixed metal compliance placard and a safety certificate signed by our licensed engineers. The placard identifies the structure the way the standards require — including the relevant model and equipment information — so your machine is documented and ready for inspection. This is your proof of compliance for OSHA, MSHA, insurers, and your own safety records.

We’ve worked on virtually every major brand of heavy equipment, including Caterpillar, Volvo, Link-Belt, Sandvik, and Broce, among many others. Our strong one-on-one relationships with all major manufacturer dealerships mean we can source information and handle ROPS and FOPS repairs and certifications across brands. Whatever badge is on your machine, ask us — we’ve likely done it before.

We serve construction, mining, agriculture, forestry, aggregates, and other industries that rely on heavy equipment. Our clients range from independent owner-operators to large operations such as Vulcan Materials, Martin Marietta, and Heidelberg Materials. Wherever heavy equipment operates, rollover protection matters — and we keep it compliant.

We are a U.S.-based company providing nationwide coverage — all 50 states, including Alaska and Hawaii. Because we travel to wherever your machine is located, distance is not a barrier to getting certified. Call (206) 947-1396 to schedule service in your area.

We certify to the recognized federal and industry standards for rollover protection, including SAE J1040 (ROPS for construction, earthmoving, forestry, and mining machines) and SAE J1194 (ROPS for wheeled agricultural tractors), which are the criteria referenced by OSHA’s construction rules (29 CFR Part 1926, Subpart W) and MSHA’s surface equipment rule (30 CFR 57.14130). Our licensed structural engineers certify that your repaired or modified structure meets the applicable performance criteria before your machine returns to service.

Getting started is simple and free. Take a few clear photos of your machine’s damage and contact us or call (206) 947-1396. Our engineer will review the photos at no charge, tell you whether your ROPS can be repaired and certified, and walk you through the next steps. There’s no cost and no obligation to find out where you stand — so reach out today and get your equipment safe, compliant, and back to work.
