起升機(jī)構(gòu)等級計算及安全原則

1、起升機(jī)構(gòu)等級計算及安全原則 起升機(jī)構(gòu)的安全運(yùn)行周期取決于是否按特定的工作等級正確使用。依據(jù)國家標(biāo)準(zhǔn)規(guī)定，起重機(jī)的起升機(jī)構(gòu)工作等級由載荷譜和日均運(yùn)行當(dāng)量時間確定。 safe and effective operation of the hoist is dependent on correct classification of the hoists operation group. according to fem9.511 and china standard the hoists operating group can be determined from load spectrum an

2、d average daily operating time. 1載荷譜 load spectrum 載荷譜可以依據(jù)下面表格確定 the load spectrum can be determined from the table below 輕級 有時吊滿載 常常吊輕載 固定載荷輕 中級 有時吊滿載 常常吊輕載 固定載荷半載 重級 重復(fù)吊滿載 常常吊半載 固定載荷重 超重級 幾乎全吊滿載 固定載荷超重 light occasional full load usually light load small fixed load medium occasional full load usual

3、ly light load average fixed load heavy repetitive full load usually average load heavy fixed load very heavy usually almost full load very heavy fixed load 2日均當(dāng)量使用時間average daily operating time 日均當(dāng)量使用時間可以依據(jù)實(shí)際使用時間按統(tǒng)計方法測算，參照公式如下： the average daily operating time of the hoist can be calculated from the

4、 running time of the hoisting machinery (hours/day): 參照公式 formula t=(2 x n x h x t)/(v x 60) h = 平均起升高度average hoisting height (m) n = 平均每小時工作循環(huán)次數(shù)number of work cycles per hour (cycles/h) t = 日均工作時間 daily working time (h) v = 起升速度hoisting speed (m/min) 3工作級別確定determining the operating group of the h

5、oist 當(dāng)載荷譜和日均當(dāng)量使用時間確定后，可以依據(jù)下面表中數(shù)據(jù)查出工作級別： when the load spectrum and the average daily operating time of the hoist are identified, the hoists operating group is obtained from the table below: 載荷譜 load spectrum 日平均當(dāng)量使用時間average daily operating time iso(gb) / fem (小時/天hours per day) 1 2 4 8 16 輕級 light

6、m3 1bm m4 1am m5 2m m6 3m 中級 medium m3 1bm m4 1am m5 2m m6 3m m7 4m 重級 heavy m3 1bm m4 1am m5 2m m6 3m m7 4m 超重級 very heavy m4 1am m5 2m m6 3m m7 4m 4 安全操作原則 safe working principles 安全使用起重機(jī)、避免對人員和財物的損害的關(guān)鍵因素之一是慎重地按照安全操作規(guī)范正確使用起重機(jī)。 carefully following safe working principles is one of the most effectiv

7、e ways of preventing damage to property and injury to personnel. 所有與起重機(jī)相關(guān)人員，包括操作員、維護(hù)人員、車間主任等，應(yīng)熟悉起重機(jī)的操作規(guī)程。 the operator, service man and work manager for the hoist should be familiar with the safe working principles for the hoist. 用戶自己的或第三方的經(jīng)過起重機(jī)廠家培訓(xùn)的維護(hù)隊伍是安全使用的保證。 a service team from customer or third party trained by manufacturer for operating the hoist and any maintenance services is needed. 很多事故或損害來自錯誤使用或不當(dāng)?shù)木S護(hù)，經(jīng)培訓(xùn)的有經(jīng)驗的維護(hù)人員和操作員可以起到有效預(yù)防作用。 misuse of the hoist or improper servicing may result in an accident that cannot be prevented by the safet
