QDY型通用橋式起重機



QDY型通用橋式起重機是在滿足GB/T14405-2011《通用橋式起重機》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、制造;適用于鑄造車間搬運、澆注融熔金屬工作和裝卸、搬運物料及臺模使用。
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:
1.本機由箱型橋架、大車運行、小車部分及電氣系統(tǒng)所組成,其基本結(jié)構(gòu)形式與QD型通用橋式起重機相同。
2.采用H級絕緣冶金起重專用電動機。
3.升降機構(gòu)裝設(shè)有兩套獨立工作的制動器(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.
Performance data
Range of lifting load 5t、10t、 16/3.2t、20/5t、32/5t、50/10t
Range of span 7.5~31.5m
Allowed crane classification group A7
Main features:
1.The machine is composed of boxed bridge,travelling mechanism , trolley and electrical system,whose features are similar fo those of QD crane.
2. It adopts H-insulated motor especially for metallurgy crane.
3. The hoisting mechanism is equipped with two set of brakes (dual brake)which can work independently,as well as load-limiter and dual hosting-displacement limiter.
4. The pulley is made of cast steel and the rope is resistant to high temperature.
5. If necessary, special measures should be taken to protect the bridge from therma-radiated sources and eleetrical equipment from dust and high-temperature environments.
