The following specification details OSHA and ANSI annual testing and inspection for aerial, digger
derrick, under-bridge
Equipment inspection and crane trucks:
1.0 AERIAL PERSONNEL DEVICE TEST AND INSPECTION REQUIREMENTS
1.1 Aerial personnel device shall be inspected and tested per ANSI/SIA A92.2 most current version and
shall satisfy OSHA.
1.2 Testing and inspecting shall include the following, but not be limited to the following,
particularly when OSHA and/or ANSI/SIA A92.2 most current version calls for more or
different inspection and testing:
I. STRUCTURAL TESTS
A. Visual Inspection: A complete inspection of accessible areas including:
1. Outriggers; Pads, structure, welds, bolts, hoses, cylinders, valves, pins and retainers.
2. Chassis; Truck frame, aerial sub-frame, suspension, PTO, pintle hook, and components
of the brake,
steering, electrical, air, hydraulic, exhaust, and cooling systems.
3. Pedestal; Mounting bolts and welds, pedestal structure, diagonal brace, attachment
welds or pins,
hydraulic swivel joint, hydraulic components, swing drive gearbox mounting bolts,
backlash between swing pinion or bullgear, electric collector ring and brushes and lower
control operation.
4. Rotation Bearing; Upper and lower bearing attachment weld and bolts, vertical movement
of bearing, and proper torque on accessible bearing bolts.
5. Turntable; Turntable structure, bucket leveling cables, leveling cylinders, compensating
chains or
sprockets, and hydraulic system components.
6. Lower Boom; Boom structure, welds, lift cylinders and attachment, hydraulic system,
leveling cables or rods, upper or extend cylinder and attachment, push links, boom rest
supports, tie-down straps, lower insulator and mounting, extension roller assembly and
wear pads.
7. Elbow; Elbow structure, hydraulic hoses and leveling cables.
8. Upper Boom (Extension); Structure, welds, leveling cables or rods, wear pads, upper
insulator and mounting, hydraulic lines and components, jib structure and mounting, tool
circuit hoses and fittings, pole claw arms and mounting brackets.
9. Platform (Bucket); Mounting bracket bolts, leveling system, exterior condition, control
operation and hydraulic lines and components.
10. Digger and Auger; digger mounting arm and housing, gearbox, auger, digger wind-up
bracket or rope, auger stop bracket, lock mechanism and control operation.
11. Winch; Mounting brackets, bolts, pins; gearbox, hydraulic components, load line, and
controls.
12. General; Load rating chart, electrical hazard placards, MADDDC placards and upper or
lower control operation placards.
The visual inspection includes removal of inspection cover plates as necessary to do a
thorough job.
B. Acoustic Emission (AE) Test: AE is the accepted industry method for testing
fiberglass and steel structures. The AE test includes attaching sensitive sensors to the
structural fiberglass and metal components from the bucket down to the outrigger or
chassis subframe. A test load of 1-1/2 or 2 times the rated load (specified by customer) is
applied to the boom. A computer system monitors sounds emitted by defects that are
growing during the test load. The computer selects the critical noise emissions and prints
a summary report. A test load of 1-1/2 times rated load will be applied to the boom or
bucket. A print out showing the result will be attached to the test report for each unit that
it applies to. Test results are to be reviewed by the engineering staff from the testing
company.
C. Magnetic Particle Inspection: Magnetic particle is a nondestructive test method used
to identify surface cracks on ferrous material. It is performed on all critical welds, plates
and castings of items listed in Part A during the visual inspection.
D. Dye Penetrant Inspection: Dye Penetrant is a nondestructive test method used to
identify surface cracks and works on any structural surface including all critical welds,
plates, castings made of non-ferrous material and any area requiring verification in Part C
or Part E.
E. Ultrasonic Inspection: Ultrasonic is a nondestructive test method used to detect flaws
in accessible critical pins. Use of ultrasonic reduces the number of pins that have to be
removed for inspection. Pins with flat end surfaces and do not have drilled holes are best
suited for ultrasonic.
F. Torque Testing: Torque testing all critical fasteners in accessible areas including upper
and lower rotation bearing, swing gearbox, boom connections, and platform mounting.
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
A DC dielectric test as specified by ANSI standards. The dielectric 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. REPORT AND CERTIFICATION
Defects found during the inspection and tests are classified for degree of severity and
printed on a computerized report. If the inspection reveals that repairs or rework are
required by the customer, details of the work will be outlined on the report. The Contract
Vendor’s technician will review the initial report with the customer’s authorized
representative (CAR). A signed and dated copy of the initial test report listing any defects
is left with the CAR. If repairs or rework need to be completed before the equipment is
certified, the Contract Vendor will provide any additional inspections needed for the
equipment to be certified.
The final test is reviewed by the Contract Vendor’s staff engineers and the final report is
mailed to CAR. The Contract Vendor retains a copy of the test report on file. The final
test/inspection report must be mailed to the CAR within 30 days of the final inspection.
