LB型防爆梁式起重機

LB型防爆梁式起重機依據(jù)JB/T10219標準所設計、制造；本產(chǎn)品適用于有易燃、易爆性氣體的化工車間、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，工作級別為A3～A5級。

主要特點：

1.本系列產(chǎn)品主、端梁結構采用LDA型電動單梁起重機箱型主粱及端梁結構形式。
2.起升機構匹配單速或雙速升降的防爆型鋼絲繩電動葫蘆。

3.大車運行匹配BZDY防爆電動機，大車運行速度不超過20m／min。

4.控制箱、安全開關及電氣設備均采用防爆型；葫蘆導電及大車供電為軟電纜導電。
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.
