QDY型通用橋式起重機(jī)

QDY型通用橋式起重機(jī)是在滿足GB/T14405-2011《通用橋式起重機(jī)》技術(shù)標(biāo)準(zhǔn)的基礎(chǔ)上，根據(jù)國家質(zhì)檢辦特【2007】375號文件要求所設(shè)計(jì)、制造；適用于鑄造車間搬運(yùn)、澆注融熔金屬工作和裝卸、搬運(yùn)物料及臺模使用。
本產(chǎn)品起重量般為5t、10t 、16/3.2t、20/5t、32/5t、50/10t，跨度為7.5～31.5m，工作級別為A7級。

主要特點(diǎn)：
1.本機(jī)由箱型橋架、大車運(yùn)行、小車部分及電氣系統(tǒng)所組成，其基本結(jié)構(gòu)形式與QD型通用橋式起重機(jī)相同。
2.采用H級絕緣冶金起重專用電動機(jī)。
3.升降機(jī)構(gòu)裝設(shè)有兩套獨(dú)立工作的制動器（雙制動)，并裝設(shè)重量限制器及雙重上升限位器。
4.采用鑄鋼滑輪和耐高溫鋼絲繩。
5.必要時(shí)對橋架結(jié)構(gòu)進(jìn)行隔熱處理．其電器設(shè)備采取防粉塵和高溫的防護(hù)處理。

????QDY overhead crane in accordance with GB/T14405-2011 standard and the request of Office of Quality Supervision Special【2007】375 document is applicable to convey molten metal and assemble modules in foundry.
