Zlo\u017eka kr\u00fatiaceho momentu statick\u00e9ho za\u0165a\u017eenia<\/div>\n

Statick\u00e1 zlo\u017eka nap\u00e4tia p\u00e1su na naklonenom p\u00e1se je hmotnos\u0165 v\u0161etk\u00e9ho materi\u00e1lu na p\u00e1se \u00d7 sin (uhol sklonu). Pri 15-stup\u0148ovom sklone s 2 000 kg uhlia na 50-metrovom p\u00e1se je statick\u00e1 \u0165a\u017en\u00e1 sila p\u00e1su len z v\u00fd\u0161ky 2 000 \u00d7 9,81 \u00d7 sin(15\u00b0) = 5 080 N.

Dynamick\u00e1 zmena za\u0165a\u017eenia<\/div>\n

Nakladanie bansk\u00e9ho materi\u00e1lu na p\u00e1s v mieste pod\u00e1vania sa m\u00f4\u017ee meni\u0165 od nuly do maxim\u00e1lnej menovitej priepustnosti v z\u00e1vislosti od cyklu nakladacieho zariadenia (bager, n\u00e1kladn\u00e9 auto, pod\u00e1va\u010d).

Pomer medzi nimi (faktor op\u00e1sania, z\u00e1visl\u00fd od priemeru hnacej remenice, uhla op\u00e1sania reme\u0148a a koeficientu trenia) ur\u010duje minim\u00e1lne predp\u00e4tie reme\u0148a potrebn\u00e9 na zabr\u00e1nenie preklz\u00e1vania reme\u0148a na hnacej remenici pri maxim\u00e1lnom kr\u00fatiacom momente motora.
