LB型防爆梁式起重機(jī)


LB型防爆梁式起重機(jī)依據(jù)JB/T10219標(biāo)準(zhǔn)所設(shè)計(jì)、制造;本產(chǎn)品適用于有易燃、易爆性氣體的化工車(chē)間、煤礦井下、礦山等有爆炸性氣體的環(huán)境下使用,防爆等級(jí)ExdIIBT4,但不適用于在爆炸性粉塵環(huán)境中使用。
本系列產(chǎn)品起重量為0.5~10t,跨度一般為7.5~31.5m,工作級(jí)別為A3~A5級(jí)。
主要特點(diǎn):
1.本系列產(chǎn)品主、端梁結(jié)構(gòu)采用LDA型電動(dòng)單梁起重機(jī)箱型主粱及端梁結(jié)構(gòu)形式。
2.起升機(jī)構(gòu)匹配單速或雙速升降的防爆型鋼絲繩電動(dòng)葫蘆。
3.大車(chē)運(yùn)行匹配BZDY防爆電動(dòng)機(jī),大車(chē)運(yùn)行速度不超過(guò)20m/min。
4.控制箱、安全開(kāi)關(guān)及電氣設(shè)備均采用防爆型;葫蘆導(dǎo)電及大車(chē)供電為軟電纜導(dǎo)電。
5.本產(chǎn)品操縱形式為地面防爆手把按鈕操縱。
Complying with JB/T10219 slandard. LB explosion-proof crane is allowed to be used in flammable and explosive environments such as chemical workshops,coal mines and oil refineries. Explosion-proof grade is ExdIIBT4. Notice that it is unsuitable to be used in explosive and dust environments.
