The vast world of lifting is appropriately regulated by laws and standards that, in order toensure worker safety, call for controls, maintenance and periodic checks of both cranes and so-called below-the hook equipment. Under the spotlight are all those devices that are used together to handle all types of loads. Those most subject to checks are chains, cables, balancers, pins, lifting hooks, welding and structural parts. Thanks to a specialist team of technicians, Ferrari Industria SA offers anall-round service as well as a checking service for electric hoists, cranes and related components.Specifically, it carries out annual and quarterly checks, on-site maintenance of parts subject to wear and the drawing up of checking registers, also required by current legislation.The checks are strictly carried out in non-destructive manner: the verification tests have been designed to highlight any anomalies or defects with the examined part, while preserving its integrity.
The test involves a liquid penetrant being spread on a surface or the part itselfis immersed in the liquid. The liquid is then removed and a developer applied to reveal the appearance of possible abnormalities. A test suitable for non-ferromagnetic, unpainted and perfectly clean material.
It allows the identification of irregularities, superficial or shallow subsurface cracks on ferrous metal parts. It is based on the principle of attraction in a magnetic field of dispersed ferromagnetic particles near to any possible imperfections. The advantages of such applications lie in the flexibility, speed of execution and practicality, since the testing can be carried out directly onsite.
Specific ultrasonic equipment means it is possible to detect defects on metallic, both ferrous and non-magnetic, systems. This type of testing makes it possible to verify irregularities in the deepest part of the structure inspected; these irregularities arise through wear, overloading and particularly strenuous usage.
Structural checks These checks mainly target the structural inspection of load-bearing parts, laminates, pins and welding; the checks are carried out by cleaning the relevant areas, evaluating the most appropriate method to be used, detecting and repairing any cracks, and finally producing a technical report.
