Aerial Device Test and Inspection
Properly maintained and tested aerial devices are essential to the safe and economical operation of a fleet. Operators and their co-workers rely on the aerial devices to perform structurally, mechanically, functionally and dielectrically as intended.
WHY SHOULD AERIAL DEVICES BE TESTED?
Aerial devices have been designed and built with adequate safety factors however in-service accidents, overloads, and fatigue can cause problems to develop. Also, regular annual inspections are required by OSHA and ANSI. A thorough, regularly scheduled inspection and test program can identify developing problems before they cause injuries or downtime. Early identification of defects are less expensive to repair than if they are left to develop into major failures. Many equipment managers have experienced substantial monetary savings by using written test reports to obtain competitive quotations for repairing, rebuilding, and remounting.
I. STRUCTURAL TESTS
II. FUNCTIONAL and OPERATIONAL TEST
A functional and operational test is performed to check the operation of controls, bearings, pins, bushings, cylinders, holding valves, bucket leveling mechanisms, outriggers, etc. This test will also find worn swing bearings or gearboxes, worn pins or bushings, and loose fasteners critical to the operation of the aerial.
III. DIELECTRIC TEST (AC OR DC)
A dielectric test up to 100kV as specified by ANSI standards. The dielectri test verifies the electrical insulating strength in the FRP upper and lower booms, bucket, liners, FRP extensions on digger derricks, tool circuits, and upper control system.
IV. OPTIONAL TESTS
V. REPORT and CERTIFICATION
Defects found during the inspection and tests are classified for degree of severity and printed on a computerized report. Ttechnicians will review the report with the customer designated representative. A signed and dated copy of the test report listing the defects discussed is left with the representative.
The report is reviewed by staff engineers and the final report is mailed to the designated customer representative. The testing company retains a copy of the test report on file. Units that need rework require verification of repair or retest in the customer file.
