運行式環鏈電動葫蘆必須依(yi)靠電(dian)(dian)力才能啟動(dong)電(dian)(dian)動(dong)葫(hu)蘆(lu)的電(dian)(dian)機，讓重(zhong)物在遙控器的控制(zhi)下(xia)做出(chu)升(sheng)降重(zhong)物的動(dong)作(zuo)，如果沒有電(dian)(dian)源(yuan)供(gong)應或者電(dian)(dian)壓不穩定都會影響到電(dian)(dian)動(dong)葫(hu)蘆(lu)的效(xiao)率，而且隨(sui)著(zhu)電(dian)(dian)動(dong)葫(hu)蘆(lu)規格級別的擴大，它所(suo)需電(dian)(dian)壓也就越高，有的工廠還需要專(zhuan)(zhuan)門(men)為電(dian)(dian)動(dong)葫(hu)蘆(lu)安裝(zhuang)一個專(zhuan)(zhuan)業的控制(zhi)箱來供(gong)電(dian)(dian)。

控制(zhi)箱又被稱(cheng)為電(dian)(dian)(dian)(dian)(dian)源箱，可以把電(dian)(dian)(dian)(dian)(dian)力電(dian)(dian)(dian)(dian)(dian)纜電(dian)(dian)(dian)(dian)(dian)能引導到電(dian)(dian)(dian)(dian)(dian)動(dong)葫(hu)蘆(lu)機(ji)身(shen)上(shang)，還(huan)自帶(dai)熔斷(duan)器的隔離開關(guan)，起到保護電(dian)(dian)(dian)(dian)(dian)動(dong)葫(hu)蘆(lu)電(dian)(dian)(dian)(dian)(dian)機(ji)的作用。給運(yun)行式環鏈電(dian)(dian)(dian)(dian)(dian)動(dong)葫(hu)蘆(lu)安裝(zhuang)控制(zhi)箱可以實現電(dian)(dian)(dian)(dian)(dian)動(dong)葫(hu)蘆(lu)操(cao)控功能，而控制(zhi)箱通(tong)常(chang)都是安裝(zhuang)在工(gong)字鋼梁上(shang)，位于電(dian)(dian)(dian)(dian)(dian)動(dong)小車(che)的側面，和按鈕裝(zhuang)置、凸輪限位開關(guan)以及連接導線等裝(zhuang)置共同組成了電(dian)(dian)(dian)(dian)(dian)動(dong)葫(hu)蘆(lu)的電(dian)(dian)(dian)(dian)(dian)氣(qi)裝(zhuang)置。

固定式環鏈電動葫蘆的控制箱上只安裝了一條電線，而運行式環鏈電動葫蘆的控制箱外(wai)往往需要安裝多條電線。
