20C below zero and 40C up zero co, the wetness 1s no


禁止吊運熔化金屬、有溝物品及易燃易爆物品



It is banned to lift melted metals, poisonous, combustible and explosive objects
3.環境條件 environment condition



此規定不同時,應在訂貨時明使用地的電源電壓和頻率),電動機和電器控制設備上允許電壓波動的上 (1)起重機的電源為三相交流,額定頻率為50이z或60lz,額定電壓為220v-60V(如電源電壓、頻率與
下限為士10%。起重機內部電壓損失不大於3
The power source of crane is 3-phase alternating current, 501lz or 60l frequency and
loy-860y (ol tage clear indication of the over source vol tue and frequeney when has
an order if power source voltage is different from above). The upper and below limit of
allowable voltage fluctuation of motor and electric control device is at+10 of rated
voltage, The voltage loss of crane inside =%.
(2)吊運物品對起重機吊鉤部位的射射熱溫度不不超過3100℃,The radiation temperature of lifted ob ject towards hook part is no more than 3000
3)環境溫度不超過+40℃,在24h內平均溫度不超過+35℃。
The environment temperature is no more than"40C, The average temperature is no torethan+35℃。
4.噪聲 noise
起重機在非密閉性廠房內,無其它噪聲干擾和起升高度不小於5m的情況下,在地面上測量,其整機聲不大於85dB(A)
The noise should bes85db(A)when there is no other noise and lifting height is no more
than 5M in non-tightness workshop
二、起重機的結構和性能參數 Structure and performance parameter
起重機的結構主要由三部分組成:橋架、電動葫蘆和電氣系123統(見圖2及隨機圖)
The crane is comprised of loading bridge, electric
hoist and electric system. (See diagram 2 and stochasticdiagram)
橋架用來支撐和縱向移動載荷,由金屬結構和運行機構組
成。金屬結構包括主梁、端端梁及主、端梁連接三部分。運行機構
由驅動裝置、傳動裝置、制動裝置和車輪組四部分組成。電動
葫蘆承擔昇降和橫向移動載荷。電氣系統由主迴路和控制迴路組成
bridge used to bear and remove loads
longitudinally is comprised of metal structure parts and
travel ing mechanism. Metal structure consists of main
beam, end carriage and connection parts of main beam
unit, gearing, brake and end carriage. Traveling mechanism consists of drive id wheel group. Electric 圖1運行機構 Traveling mechanism
