Pic. 1. “El-Kran” wheel marking pattern
All finished crane wheels manufactured at the production facilities of "El-Kran", have an obligatory factory impact markings.
In this case, we strictly follow the appropriate state regulations for producers, namely paragraph 2.7. GOST 28648-90:
“2.7. Each wheel, supplied as a spare part, must have an impact marking, dimensions D x B and QC department stamp, on the surface of the rim.
Wheels supplied as a part of a crane or trolley assembly must have only a QC department marking.”
Crane wheels supplied as spare parts without relevant markings can be considered as a low-grade product and their usage is prohibited to be installed on any operating equipment.
