style="text-indent:25px">塔吊滑鉤原因：一、塔吊配電箱里的接觸器電源進(jìn)出線固定螺絲松動、接線端子板接線栓接觸不良、接觸器主觸點(diǎn)接觸不良。二、電機(jī)轉(zhuǎn)子、定子線圈的接線栓燒蝕接觸不良。三、高、低速電機(jī)制動剎車片磨損超過規(guī)定要求。四、變速箱齒輪打壞，廣西塔吊生產(chǎn)廠家，固定齒輪螺栓松動。五，廣西塔吊生產(chǎn)廠家、缺相保護(hù)器不起作用。預(yù)防措施年來由于高層建筑迅猛發(fā)展，施工中垂直運(yùn)輸機(jī)械塔吊的使用量急劇增加，塔吊傾覆的重大安全事故也屢屢發(fā)生，如何預(yù)防是關(guān)鍵。一、司機(jī)在工作中出現(xiàn)滑鉤現(xiàn)象后要冷靜，及時通知信號工讓地面人員走開。按照操作規(guī)程規(guī)定進(jìn)行操作，起鉤、轉(zhuǎn)臂、走小車等方式，將重物放在現(xiàn)場無人區(qū)內(nèi)。二、做好班前、班中、班后的安全檢查工作，要用眼看、耳聽、手動等形式進(jìn)行檢查。三，廣西塔吊生產(chǎn)廠家、不定期的進(jìn)行各種線路連接點(diǎn)的檢查與緊固。四、要定期檢查各制動器剎車片是否正常，電機(jī)接線栓接觸是否良好，以及接觸器主觸點(diǎn)接觸是否正常。五、維修人員對工作要認(rèn)真負(fù)責(zé)，嚴(yán)格按照安全操作規(guī)程要求去做，該換的配件一定要換，做好工作后的檢查、試運(yùn)轉(zhuǎn)工作。塔吊使用之前的注意事項(xiàng)有哪些？廣西塔吊生產(chǎn)廠家</p><div

我們通常所見的塔吊一般為附著式塔式起重機(jī)又稱自升塔式起重機(jī)專，直接固定在建筑屬物或構(gòu)筑物近旁的混凝土基礎(chǔ)上，隨著結(jié)構(gòu)的升高，不斷自行接高塔身，使起重高度不斷增大。 </p> <p> 附著式塔式起重機(jī)的自升接高目前主要是利用液壓缸頂升，采用較多的是外套架液壓缸側(cè)頂式。其頂升過程，可分為5個步驟： </p> <p> 1.將標(biāo)準(zhǔn)節(jié)吊到擺渡小車上，并將過渡節(jié)與塔身標(biāo)準(zhǔn)節(jié)相聯(lián)的螺栓松開，準(zhǔn)備頂升。 </p> <p> 2.開動液壓千斤頂，將塔吊上部結(jié)構(gòu)包括頂升套架向上頂升到超過一個標(biāo)準(zhǔn)節(jié)的高度，然后用定位銷將套架固定。于是塔吊上部結(jié)構(gòu)的重量就通過定位鎖傳遞到塔身。 </p> <p> 3.液壓千斤頂回縮，形成引進(jìn)空間，此時將裝有標(biāo)準(zhǔn)節(jié)的擺渡小車開到引進(jìn)空間內(nèi)。 </p> <p> 4.利用液壓千斤頂稍微提起標(biāo)準(zhǔn)節(jié)，推出擺渡小車，然后將標(biāo)準(zhǔn)節(jié)平衡的落在下面的塔身上，并用螺栓加以聯(lián)接。 </p> <p> 5.拔出定位銷，下降過渡節(jié)，使之與已接高的塔身聯(lián)成整體。如一次要接高若干塔身標(biāo)準(zhǔn)節(jié)，則可重復(fù)以上工序。廣西塔吊生產(chǎn)廠家塔吊作業(yè)前要求有哪些？</p><div style="width:100%;text-align: center;"><img style="max-width: 640px;

塔吊安裝后,應(yīng)進(jìn)行整機(jī)技術(shù)檢驗(yàn)和調(diào)整,經(jīng)分階段及整機(jī)檢驗(yàn)合格后,方可交付使用。在無載荷情況下,塔身與地面的垂直度偏差不得超過4/1000。塔吊的電動機(jī)和液壓裝置部分,應(yīng)按關(guān)于電動機(jī)和液壓裝置的有關(guān)規(guī)定執(zhí)行。 </p> <p> (7) 塔吊的金屬結(jié)構(gòu)、軌道及所有電氣設(shè)備的金屬外殼應(yīng)有可靠的接地裝置,接地電阻不應(yīng)大于4Ω,并應(yīng)設(shè)立避雷裝置。 </p><p style="text-indent:25px">塔吊安裝方法：檢查路基、軌道鋪設(shè)是否符合要求，埋設(shè)地錨，根據(jù)立塔旋轉(zhuǎn)搬起方向、塔身總高度等情況，決定地錨的位置。地錨分主地錨和輔助地錨。主地錨是塔身立起的關(guān)鍵，旋轉(zhuǎn)搬起塔身的全部荷載由主地錨承擔(dān)，而且在拆塔時，仍需要使用地錨，所以必須認(rèn)真埋設(shè)，使其達(dá)到要求的承載力，并作好防腐處理。地錨輪的中心必須與軌距的中心相一致，以保證塔身搬起過程中，始終沿軌距中心面旋轉(zhuǎn)，不產(chǎn)生偏心，使門架均衡受力。輔助地錨的作用是在塔身搬起時，隨旋轉(zhuǎn)隨放松鋼絲繩，此地錨是做為保險(xiǎn)鋼絲繩的錨定點(diǎn)，以防止塔身在旋轉(zhuǎn)過程中，發(fā)生向相反方向倒塔的事故。塔吊作業(yè)中要求有哪些？</p><div

從塔吊行業(yè)的發(fā)展來看，行業(yè)與國家經(jīng)濟(jì)、建筑/房地產(chǎn)高度相關(guān)，因此，從國家經(jīng)濟(jì)走勢以及房地產(chǎn)行業(yè)發(fā)展趨勢看塔吊行業(yè)發(fā)展具有一定科學(xué)意義。2010年，中國經(jīng)濟(jì)延續(xù)了2009年以來的回升向好態(tài)勢，為各個行業(yè)發(fā)展奠定了良好的基礎(chǔ)，房地產(chǎn)行業(yè)隨之迅速回升，塔吊行業(yè)也有明顯上升，根據(jù)中國工程機(jī)械協(xié)會統(tǒng)計(jì)，2010年塔吊銷量突破4萬臺。2011年受房地產(chǎn)調(diào)控、動車事故、日本地震等影響，塔吊市場規(guī)模擴(kuò)張速度有所放慢，但仍保持10%以上的增速。如何確定塔吊的位置？玉林塔吊廠家推薦</p><p

俯仰變幅起重臂塔式塔吊是靠起重臂升降未實(shí)現(xiàn)變幅的，其優(yōu)點(diǎn)是：能充分發(fā)揮起重臂的有效高度，機(jī)構(gòu)簡單，缺點(diǎn)是小幅度被限制在大幅度的30%左右，不能完全靠近塔身，變幅時負(fù)荷隨起重臂一起升降，不能帶負(fù)荷變幅。 </p> <p> 小車變幅起重臂塔式塔吊是靠水平起重臂軌道上安裝的小車行走實(shí)現(xiàn)變幅的，其優(yōu)點(diǎn)是：變幅范圍大，載重小車可駛近塔身，能帶負(fù)荷變幅，缺點(diǎn)是：起重臂受力情況復(fù)雜，對結(jié)構(gòu)要求高，且起重臂和小車必須處于建筑物上部，塔尖安裝高度比建筑物屋面要高出15-20米。廣西塔吊生產(chǎn)廠家</p><p
