　　低凈空手拉葫蘆專(zhuān)為有限的空間尺寸設(shè)計(jì)，大大縮短了手拉葫蘆下吊鉤到橫梁之間的距離，較低的凈空尺寸為140mm，擴(kuò)大了有效提升空間，具有較低的凈空尺寸。低凈空手拉葫蘆適用于單軌運(yùn)行，特別適用于在較低的建筑物、臨時(shí)搭建的廠房?jī)?nèi)或起升空間有限的場(chǎng)所。

　　低凈空手拉葫蘆較小型號(hào)為1T/3M,較大型號(hào)為10T/3M,鏈條可根據(jù)起升高度的要求定做，工字鋼尺寸也可根據(jù)客戶(hù)的需要定做。

　　低凈空手拉葫蘆通過(guò)特定的設(shè)計(jì)能使重物升至距離固定處較近，較大程度上縮小距離，實(shí)現(xiàn)單軌小車(chē)與手拉葫蘆的低凈空空組合。除此之外，低凈空凈空手拉葫蘆還具有自重輕，手拉力小，經(jīng)濟(jì)實(shí)用等優(yōu)點(diǎn)。

  ? ??關(guān)于電動(dòng)葫蘆的保護(hù)裝置，首先要把它牢固得安裝好，并且性能要可靠穩(wěn)定，還要有足夠的強(qiáng)度和剛度，其次就是不能妨礙生產(chǎn)和操作，對(duì)安全有保證性，最后就是質(zhì)量要經(jīng)久耐用，不影響電動(dòng)葫蘆的一系列操作，保護(hù)裝置不能給作業(yè)者造成危害。 ? 地址：河北省清苑縣凱澄大道888號(hào) 公司網(wǎng)址： 聯(lián)系電話(huà)：0312-3012118&

• 鋼絲繩電動(dòng)葫蘆的部件組成

  鋼絲繩電動(dòng)葫蘆組成的部分大致可分為：減速器、控制箱、鋼絲繩、錐形電動(dòng)機(jī)、按鈕開(kāi)關(guān)。 減速器作用：是采用三級(jí)定軸斜齒輪傳動(dòng)機(jī)構(gòu)，齒輪和齒輪軸均經(jīng)過(guò)熱處理的合金鋼制成，箱體，箱蓋由優(yōu)質(zhì)鑄鐵制成，裝配嚴(yán)密，密封良好。 控制箱作用：是采用能在緊急情況下切斷主電路，并帶有一個(gè)上下行程保護(hù)段火限位器的裝置。 鋼絲繩作用：是采用型起重鋼絲繩，它保證了經(jīng)久耐用。 錐形電動(dòng)機(jī)作用：起升電機(jī)采用較大的動(dòng)力矩錐形轉(zhuǎn)子

• 鋼絲繩電動(dòng)葫蘆有哪些技術(shù)特點(diǎn)

  ? ?????? 鋼絲繩電動(dòng)葫蘆由于是由鋼絲繩來(lái)起吊物品，所有為了避免鋼絲繩跳槽，它安裝了導(dǎo)繩器，這樣在使用鋼絲繩電動(dòng)葫蘆時(shí)會(huì)非常的順利。 按照**標(biāo)準(zhǔn)鋼絲繩如有5根起毛刺，為了安全起見(jiàn)，應(yīng)立即更換鋼絲繩。這些措施可以有效的加強(qiáng)電動(dòng)葫蘆的使用壽命。 鋼絲繩電動(dòng)葫蘆雙剎車(chē)系統(tǒng)安全可靠，而且鋼絲繩電動(dòng)葫蘆吊上吊下都有極限開(kāi)關(guān)，防止**

• 起吊中防爆電動(dòng)葫蘆的前期準(zhǔn)備工作

  1、在使用防爆動(dòng)電葫蘆起吊重物之前，應(yīng)檢查起吊周?chē)?20~30m)環(huán)境是否安全，進(jìn)行起吊工作前，先對(duì)手動(dòng)葫蘆進(jìn)行負(fù)荷實(shí)驗(yàn)。 2、單個(gè)起吊物體重量不得**過(guò)規(guī)定值的80%，起吊錨桿應(yīng)采用高強(qiáng)樹(shù)脂螺紋錨桿，直徑不小于20mm，長(zhǎng)度不小于1.8m，并采用全長(zhǎng)錨固。起吊錨桿連接的起吊吊環(huán)承載力不得小于被起吊重物重量的6倍。 3、起吊前期準(zhǔn)備應(yīng)檢查起吊點(diǎn)的可靠性，使物件微離地面，進(jìn)行試吊，試吊高度100~2
