Devices and Methodologies

In the field and in the lab, we work with a range of devices and methodologies, including our own proprietary systems, to ensure the optimal approach for your unique needs.

  • Our state-of-the-art laboratories use a variety of complementary NDT methods to paint a comprehensive picture of component condition. When a part is too large or too delicate to ship, our labs can provide on-site NDT testing and quick turnaround times.
  • Our certified field inspectors deliver in-depth expertise in welded, bolted, or riveted steel components and welded steel structures for major bridge projects, highway signs, high mast lighting poles, and other critical infrastructure initiatives.
  • Our Lift Services team is a leader in performing inspections and non-destructive testing to ensure lift equipment is structurally sound and safe to use.

No flaw will escape detection by our advanced technologies and experienced team. When your job calls for bulls-eye accuracy, call IIA.

Operational/Safety Inspections of Lift Devices

For decades, we have provided on-site inspections and certifications to ensure the safety of ground support equipment (GSE), overhead cranes, bucket trucks, digger derricks, fire trucks and other aerial and lift devices. Our NDT expertise allows us to accurately detect surface and subsurface defects without damaging the equipment being tested. We offer a wide variety of complementary NDT, including magnetic particle testing (MT), ultrasonic testing (UT), visual and operational inspections — and more.

Engineering Solutions for Ground Support Equipment (GSE)

As a full-service company, we can also provide engineering solutions related to custom design lift devices, engineered critical lifts, outrigger mat shoring, engineered weld repairs, and load rate/derate cranes.

Overhead Crane Services

With over 20 years of experience, we are the industry leader when it comes to the fabrication and installation of new crane equipment, as well as the testing, training, maintenance, and repair of all crane systems. Our crane engineers can also assist with engineered weld repairs. Read more about our Overhead Crane Services.

Compliance Tracking

Many organizations partner with us to perform and track required ANSI or OSHA inspections and keep them in compliance. Our team is well versed in all regulatory requirements affecting lift equipment. From start to finish, we keep meticulous records of our inspection process and test results. You can trust IIA to track your testing needs and inform you well before your equipment is due for inspections. This service reduces the risk of compliance issues and allows you more time to focus on your core business.

Fire Truck Inspections

IIA is the go-to expert for top-to-bottom fire truck inspections, including hose, pump, ladder and other apparatus. Using our mobile pump tester and customized methodology, we conduct fast, thorough, and reliable services that meet or exceed NFPA guidelines. With our refined methods, we can test in one day what it takes others several days to complete — and that means less downtime for your emergency vehicles. Our expert fire department services help protect firefighters and could potentially save your department money.

Aerial & Ground Ladder Testing

As an ISO/IEC 17020 Accredited Corporation, IIA offers a complete inspection and non-destructive testing program to meet the current NFPA 1911, as well as 1932-2020, guidelines for testing aerial ladders, elevating platforms, water towers, and ground ladders. We test metal, fiberglass, and even wood ground ladders between 5 and 45 feet in length. These tests include visual inspections, horizontal bend test, roof hook test, and hardware test. Read more about our Aerial & Ground Ladder Testing.

Fire Hose Testing

Professional, timely service has made IIA the premier provider of fire hose testing in the United States. Our proprietary testing equipment allows us to test more feet of hose, under varying levels of pressure, faster and more accurately than any other company. Our crew supervisors and highly trained staff ensure that each hose length is both pressure tested and visually inspected. (And we guarantee that you'll love the way everything looks when we leave.) Read about the strict process we follow, and ask about our hard suction hose testing service!

IIA labels and records all data for each length of hose we test, in accordance with NFPA standards. We also maintain a computerized history of your fire company's hose for every year we service them.

Fire Pump Testing

Our state-of-the-art mobile pump testing units allow us to accurately test fire department apparatus on location with minimal downtime, and limited use of municipal water, water tankers, or cisterns. We use clean, cool water to test your pumps, which minimizes potential damage. Read about the types of fire pump testing we do.
