Structural Technology, Inc. provides a complete and comprehensive Safety Inspection Program to meet current ANSI and ASTM guidelines for performing visual and NDT inspections along with operational and functional tests on all types of aerial devices/digger derricks.  We provide a thorough inspection of all areas of the equipment, including:
 

Non-Destructive Testing (NDT)

Technicians performing NDT are ASNT SNT-TC-1A & CP-189 certified in all methods that require the  following tests:

Trans-layer Structural Analysis - The latest technology for the inspection of insulated aerial devices and digger derricks.

Acoustic Emission - Global Structural Analysis of Fiberglass and Metal Booms.

Ultrasonic Inspection  - Internal Check of Pins and Fasteners using Ultrasonic Sound Waves

Magnetic Particle/Liquid Penetrant - Welding Inspection on All Types of Metals.

Operational  & Functional Test on Aerial Manlift/Digger Derricks - A  functional test is performed to check the controls, bearings, pins, bushings, cylinders, holding valves, ladder extension cables, platform leveling mechanisms, outriggers, etc. This test also inspects for worn swing bearings/gear boxes, worn pins/bushings, and loose bolts, which are critical to the operation of the aerial device.  The operation of the  platform shall include movement of the platform from minimum to maximum elevation and extension as well as rotating platform to the left and to the right. Booms and platforms shall operate without any improper or unusual motion or sound.
