Pulley shaft must no cracks, wear of shaft neck can’t more than 30% of the original diameter, conicity can’t more than 5%, if more than this value should be replaced;
Angalia groove ya pulley kwa template, kuvaa kwa radial haipaswi kuzidi 30% ya unene, vinginevyo inapaswa kufutwa. Ambayo isiyozidi kiwango inaweza kuwa kiraka, na angalia kwa kiolezo baada ya kurekebishwa, chini na nyuma haipaswi kuwa kubwa kuliko 0.5mm, kupotoka kwa mstari wa kituo cha pulley na mstari wa kituo cha groove haipaswi kuzidi 0.2mm, kituo cha kamba cha kamba hadi kupotoka kwa uso wa mwisho haipaswi kuzidi 1mm;
Single girder Rudia crane baada ya kubadilisha, mashimo axle kuruhusu kasoro ambayo chini ya 0.25CM2, kina zisizidi 4mm;
After the assembly should be able to flexible rotation by hand, sideshake must not exceed D1000mm–pulley nominal dia.
