\u017deriavov\u00fd kladkostroj zdv\u00edha a zavesuje bremen\u00e1 proti gravit\u00e1cii.

Z\u00e1va\u017enos\u0165 nekontrolovan\u00e9ho poklesu siaha od po\u0161kodenia v\u00fdrobku a po\u0161kodenia \u017eeriavom a\u017e po smrte\u013en\u00e9 zranenia v priestoroch s obsluhou alebo nad hlavou.<\/p>\n

Pre\u010do sp\u00e4tn\u00e1 elektromotorick\u00e1 sila motora nie je dostato\u010dn\u00e1<\/div>\n

Ke\u010f sa zo \u0161tandardn\u00e9ho asynchr\u00f3nneho motora odpoj\u00ed nap\u00e1janie, rotor sa spoma\u013euje iba v d\u00f4sledku trenia.

Motor zdv\u00edhacieho zariadenia bez mechanickej brzdy umo\u017en\u00ed bremenu klesa\u0165 vplyvom gravit\u00e1cie r\u00fdchlos\u0165ou obmedzenou iba r\u00fdchlos\u0165ou lana a tren\u00edm \u2013 zvy\u010dajne 0,5 a\u017e 2,0 m\/s pre \u0161tandardn\u00fd dielensk\u00fd zdv\u00edhac\u00ed mechanizmus.<\/p>\n<\/div>\n

Extern\u00e1 brzda namontovan\u00e1 na v\u00fdstupnom hriadeli zdv\u00edhacieho zariadenia alebo na bubne re\u0165aze vy\u017eaduje samostatn\u00fa mont\u00e1\u017e, zarovnanie a ovl\u00e1dacie vedenie.

Brzdov\u00fd motor Y2EJ integruje motor a brzdu do jednej utesnenej jednotky, ktor\u00e1 zdie\u013ea jednu svorkovnicu. Nap\u00e1janie brzdy jednosmern\u00fdm pr\u00fadom je odvoden\u00e9 z rovnak\u00e9ho trojf\u00e1zov\u00e9ho nap\u00e1jania ako motor cez intern\u00fd usmer\u0148ova\u010d, \u010do zabezpe\u010duje, \u017ee brzda sa uvo\u013en\u00ed s\u00fa\u010dasne s pripojen\u00edm motora k nap\u00e1janiu a zapne s\u00fa\u010dasne s odpojen\u00edm motora od nap\u00e1jania.

2. Pru\u017einov\u00e1 brzda: Bezpe\u010dnos\u0165 pre bezpe\u010dnos\u0165 zdvih\u00e1ka<\/h2>\n

Brzdov\u00fd motor Y2EJ pou\u017e\u00edva pru\u017einovo ovl\u00e1dan\u00fa, elektricky uvo\u013e\u0148ovan\u00fa elektromagnetick\u00fa brzdu. Ide o kon\u0161trukciu bezporuchov\u00fa: pru\u017einy dr\u017eia brzdu zatiahnut\u00fa a z\u00e1\u0165a\u017e v predvolenom stave. Na uvo\u013enenie brzdy a umo\u017enenie chodu motora je potrebn\u00e1 elektrick\u00e1 energia. To znamen\u00e1, \u017ee ak\u00e9ko\u013evek preru\u0161enie nap\u00e1jania \u2013 \u00famyseln\u00e9 zastavenie, v\u00fdpadok nap\u00e1jania, vypnutie pri pre\u0165a\u017een\u00ed alebo n\u00fadzov\u00e9 zastavenie \u2013 automaticky zabrzd\u00ed a zastav\u00ed z\u00e1\u0165a\u017e bez nutnosti ak\u00e9hoko\u013evek ovl\u00e1dacieho z\u00e1sahu.<\/p>\n

\n
\n
Krok 1: Nabite sa energiou<\/div>\n

Zdvihnutie alebo spustenie st\u00fdka\u010da zapne. Trojf\u00e1zov\u00e9 nap\u00e1janie nap\u00e1ja vinutie motora; jednosmern\u00fd usmer\u0148ova\u010d nap\u00e1ja brzdov\u00fa cievku. Elektromagnet prekon\u00e1va silu pru\u017einy; brzda sa uvo\u013en\u00ed. Motor zr\u00fdchli na menovit\u00e9 ot\u00e1\u010dky v priebehu 0,5\u20131,5 s v z\u00e1vislosti od zotrva\u010dnosti z\u00e1\u0165a\u017ee.<\/p>\n<\/div>\n

\n
Krok 2: Beh<\/div>\n

Motor zdv\u00edha alebo sp\u00fa\u0161\u0165a bremeno menovitou r\u00fdchlos\u0165ou. Brzdov\u00e1 cievka zost\u00e1va pod nap\u00e4t\u00edm; brzdov\u00fd kot\u00fa\u010d sa vo\u013ene ot\u00e1\u010da bez kontaktu. Po\u010das prev\u00e1dzky nedoch\u00e1dza k opotrebovaniu.<\/p>\n<\/div>\n

\n
Krok 3: Zastavte sa a podr\u017ete<\/div>\n

St\u00fdka\u010d sa otvor\u00ed. Motor a brzdov\u00e1 cievka sa s\u00fa\u010dasne odpoja od nap\u00e1jania. Pru\u017einy zaber\u00fa do brzdov\u00e9ho kot\u00fa\u010da v priebehu 50 \u2013 150 ms. Motor spomal\u00ed z menovit\u00fdch ot\u00e1\u010dok na nulu za 0,1 \u2013 0,4 s v z\u00e1vislosti od brzdn\u00e9ho momentu a zotrva\u010dnosti z\u00e1\u0165a\u017ee. Z\u00e1\u0165a\u017e zost\u00e1va nehybne st\u00e1\u0165 bez potreby nap\u00e1jania.<\/p>\n<\/div>\n

\n
V\u00fdpadok nap\u00e1jania<\/div>\n

Rovnak\u00e9 ako v kroku 3 \u2013 brzda sa zabrzd\u00ed automaticky. Bremeno je bezpe\u010dne dr\u017ean\u00e9. Na dr\u017eanie brzdy nie je potrebn\u00fd \u017eiadny pomocn\u00fd zdroj nap\u00e1jania. Toto je bezpe\u010dnostn\u00e1 vlastnos\u0165, v\u010faka ktorej je pru\u017einov\u00e1 brzda povinn\u00e1 pre aplik\u00e1cie so zdv\u00edhac\u00edmi zariadeniami a \u017eeriavmi.<\/p>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n

Brzdn\u00fd moment mus\u00ed by\u0165 dostato\u010dn\u00fd na spomalenie bremena z menovitej r\u00fdchlosti zdv\u00edhacieho zariadenia na nulu v r\u00e1mci po\u017eadovan\u00e9ho \u010dasu zastavenia a na udr\u017eanie bremena v nehybnej polohe proti gravit\u00e1cii bez toho, aby sa sk\u013azlo pod maxim\u00e1lnym menovit\u00fdm za\u0165a\u017een\u00edm.
