Non-destructive test (NDT) must be completed annually
U.S. Consumer Product Safety Commission safety notice dated June 9, 1992 and August 2, 2000
ARMAli-Baba aka 1001 Nacht’s
1. Check for surface cracks in main arm joint weldment, main arm to center weldment, car mounting blocks and car frame weldments, tower bolt blocks weldment, tower to trailer weldment, car slewing ring mounting plate to arm weldment 2. Check for surface cracks in parent metal at weld toes, edges of holes, and flame-cut edges. 3. Check for cracks in drive-shafts in the vicinity of keyways, holes, changes in diam. and other geometric discontinuities. 4. Check for reduction in wall thickness of hollow sections especially at weld toes.
Non-destructive test (NDT) must be completed every 2 years: 1&2 check by Dye Penetrant and Magnetic Particle. 3 & 4 Use Ultrasonic to test drive shafts and wall thickness of hollow sections.
