Crane Hooks and Why They Need Inspections
Applied Technical Services’ Nondestructive Testing (NDT) group performs ASME B30.10 crane hook inspections to ensure that client equipment maintains safe operating conditions. Crane hooks sustain an uncountable number of significant stresses throughout their service life. These stresses are the result of the loads they move around — freight, construction materials, and assembled components get heavy, after all. This loading and unloading can create material fatigue over time, a strain that undermines the integrity of the crane’s hook as it can cause cracks to form and propagate. A compromised hook can fail at any time, which at best can set back work and at worst endanger everyone on the jobsite.
While crane operators can perform regular equipment inspections to check whether the hook is exhibiting visual indications of wear, some threats lie beneath the surface. Engineering codes like ASME B30.10 outline the recommended frequency and specifications of more in-depth analyses. Qualified inspectors, like ATS’ squad of Professionals, can help determine the health and remaining life expectancy of clients’ crane hooks.
ASME B30.10 and ATS' Crane Hook Inspection Capabilities
ASME B30.10 requires that crane hooks used in frequent or pulsating load cycles undergo this more rigorous periodic inspection at least once a year, or more frequently as determined by a Qualified Person such as one of our consulting engineers. To complete this assessment, our inspection team accesses the internal components of the hook (such as the hook shank, where most fatigue cracks form) and subjects them to NDT methods as they deem appropriate: magnetic particle testing (MT), liquid penetrant testing (PT), and in some cases ultrasonic testing (UT). While both MT and PT help inspectors detect discontinuities open to the surface, ultrasonic testing can locate flaws beneath the surface, as well as further evaluate the length, depth, and position of defects.
Once we have assessed the crane hook using NDT, our Engineers determine its remaining strength and establish a plan for how to safely get the most out of the equipment. They outline any recommendations when they return their findings, including whether the hook must be repaired or retired before further use. These experts perform all crane hook inspection services and calculations in accordance with the ASME B30.10 standard.
