For more than 50 years, IIA has been a leading provider of critical testing that helps protect electric line crews, firefighters and other workers.

Our highly skilled and certified technicians conduct comprehensive testing to ensure the safety of bucket trucks and other vehicle-mounted aerial devices, digger derrick equipment, and all related components. Our inspection services are performed on site and in accordance with all applicable standards.

The NDT Experts

There is no single testing method comprehensive enough to facilitate a decision about the overall structural integrity of equipment. That’s why we offer a variety of complementary non-destructive testing (NDT), including:

  • Magnetic particle and/or dye penetrant test of critical welds and castings
  • Ultrasonic testing of critical pins and bolts
  • Complete visual inspection, including the under carriage and removing all inspection plates
  • Complete operational inspection to ensure functionality
  • Dielectric Testing (AC or DC) of fiberglass booms, basket liners, insulated upper controls and live line tools
  • Structural, mechanical and hydraulic inspection
  • Stability Load Testing
  • Acoustic Emission
  • Aerial PM Service
  • DOT Inspections
  • Opacity/Smoke Diesel Test (California)

Our large and growing footprint in North America allows us to provide fast and flexible service, whether you need routine inspections or emergency repairs. We can even provide after-hours testing to minimize disruptions to your operations.

Our Inspections

Along with state and federal regulations, in the U.S., IIA follows American National Standards Institute (ANSI) guidelines adopted in 1969. These standards, A92.2 and A10.31, set forth the MINIMUM test requirements that must be considered and built into quality assurance programs for vehicle-mounted aerial devices to provide safe and proper operations. The standard includes user responsibilities for periodic inspection. At a minimum, the owner/user is to provide the following: loading, stability, visual inspections and dielectric testing of insulated units. Our Fleet Industrial Inspection Tracker (FIIT) software enhances our ability to track inspections and sort data for user-friendly, actionable reports.

Our technicians also carry most of the required safety stickers and placards and can replace missing or damaged items at a minimal cost.

Effective maintenance and inspection of aerial equipment is one of the most critical factors for ensuring the safety and productivity of utility operations personnel and other industrial workers. Partner with IIA to keep your workers safe and your organization in compliance.

Turning Data Into Knowledge

Upon completion of testing, we issue a comprehensive Fleet Safety Analysis report and discuss it with your staff. This exhaustive report covers the current condition of your equipment, necessary repairs, and recommendations for future maintenance to help your organization better manage its fleet.
