   1. 檢查減速器主要看其是否漏油。運行時箱體內有異響，就要打開箱蓋檢查。一般是因軸承損壞或齒輪齧合側隙過大、齒麵磨損嚴重等原因所致。

　2. 檢查製動器的性能、狀(zhuang)況(kuang)。製(zhi)動(dong)器(qi)是(shi)起(qi)重(zhong)吊(diao)車(che)上(shang)重(zhong)要(yao)的(de)部(bu)件(jian)，直(zhi)接(jie)影(ying)響(xiang)各(ge)機(ji)構(gou)運(yun)動(dong)的(de)準(zhun)確(que)性(xing)和(he)可(ke)靠(kao)性(xing)。因(yin)此(ci)，要(yao)認(ren)真(zhen)檢(jian)查(zha)起(qi)升(sheng)與(yu)變(bian)幅(fu)兩(liang)機(ji)構(gou)製(zhi)動(dong)器(qi)的(de)狀(zhuang)況(kuang)
，觀(guan)察(cha)製(zhi)動(dong)閘(zha)瓦(wa)的(de)開(kai)度(du)及(ji)摩(mo)擦(ca)元(yuan)件(jian)刹(sha)車(che)皮(pi)的(de)磨(mo)損(sun)情(qing)況(kuang)。帶(dai)式(shi)製(zhi)動(dong)器(qi)要(yao)注(zhu)意(yi)檢(jian)查(zha)其(qi)製(zhi)動(dong)帶(dai)的(de)鋼(gang)背(bei)襯(chen)有(you)無(wu)裂(lie)紋(wen)，製(zhi)動(dong)器(qi)的(de)傳(chuan)動(dong)是(shi)否(fou)靈(ling)活(huo)
，刹(sha)車(che)架(jia)是(shi)否(fou)完(wan)好(hao)和(he)主(zhu)彈(dan)簧(huang)和(he)輔(fu)助(zhu)彈(dan)簧(huang)的(de)彈(dan)性(xing)是(shi)否(fou)符(fu)合(he)要(yao)求(qiu)。

　5. 檢查各聯軸節有無鬆動甚至"滾鍵"。著(zhe)重(zhong)檢(jian)查(zha)彈(dan)性(xing)柱(zhu)銷(xiao)聯(lian)軸(zhou)節(jie)的(de)彈(dan)性(xing)橡(xiang)膠(jiao)圈(quan)有(you)無(wu)異(yi)常(chang)磨(mo)損(sun)
，對(dui)齒(chi)形(xing)聯(lian)軸(zhou)節(jie)要(yao)特(te)別(bie)注(zhu)意(yi)其(qi)齒(chi)輪(lun)齒(chi)圈(quan)磨(mo)損(sun)狀(zhuang)況(kuang)。因(yin)安(an)裝(zhuang)精(jing)度(du)差(cha)，在(zai)兩(liang)軸(zhou)之(zhi)間(jian)有(you)較(jiao)大(da)偏(pian)移(yi)量(liang)的(de)情(qing)況(kuang)下(xia)，表(biao)現(xian)為(wei)短(duan)時(shi)間(jian)內(nei)整(zheng)個(ge)齒(chi)圈(quan)很(hen)快(kuai)會(hui)磨(mo)禿(tu)。在(zai)起(qi)升(sheng)機(ji)構(gou)中(zhong)如(ru)有(you)此(ci)種(zhong)情(qing)形(xing)，易(yi)發(fa)生(sheng)嚴(yan)重(zhong)事(shi)故(gu)。
