It is banned to lift melted metals, poisonous, combustible and explosive objects
3.环境条件 environment condition
此规定不同时，应在订货时明使用地的电源电压和频率)，电动机和电器控制设备上允许电压波动的上 (1)起重机的电源为三相交流，额定频率为50이z或60lz，额定电压为220v-60V(如电源电压、频率与
下限为士10%。起重机内部电压损失不大于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)吊运物品对起重机吊钩部位的射射热温度不不超过3100℃，The radiation temperature of lifted ob ject towards hook part is no more than 3000
3)环境温度不超过+40℃，在24h内平均温度不超过+35℃。
The environment temperature is no more than"40C, The average temperature is no torethan+35℃。
4.噪声 noise
起重机在非密闭性厂房内，无其它噪声干扰和起升高度不小于5m的情况下，在地面上测量，其整机声不大于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、起重机的结构和性能参数 Structure and performance parameter
起重机的结构主要由三部分组成:桥架、电动葫芦和电气系123统(见图2及随机图)
The crane is comprised of loading bridge, electric
hoist and electric system. (See diagram 2 and stochasticdiagram)
桥架用来支撑和纵向移动载荷，由金属结构和运行机构组
成。金属结构包括主梁、端端梁及主、端梁连接三部分。运行机构
由驱动装置、传动装置、制动装置和车轮组四部分组成。电动
葫芦承担升降和横向移动载荷。电气系统由主回路和控制回路组成
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 图1运行机构 Traveling mechanism

钢组焊成实腹梁或用钢板组焊成箱形梁。端梁为U型槽钢组焊成箱形结构，主、端梁之间采用螺栓加抗剪凸缘连接结构或座式结构，安装方便，便于运输储存。
The main beam is made of the steel board pressed and lengthened to be"U"shape. Then its welded with i-steel together to form the beam of case shape. The crossbeam is made in the运行机构
斜跑偏造成的哨道磨损，不易出现车轮爬轨掉道故障 运行机构采用分别驱动形式(见图1)，驱动、制动靠锥形转子电动机来完成，其优点是能减轻因车轮
运行速度(m/min):地面操作一般为20、30:司机室操作为30、45、60起起重机设计有单速和双速及
变频调速等型式，一般情情况下按单速制造，用户如需其它调速方式时，应在订货合同中于以注明。
3.起升机构1
起重机安装电动葫芦组成起升机构，可起升吊运重物，并可沿主梁横向移动
4.电气系统
电动葫芦的起升运行电动机采用起动力矩较大的锥形转子电动机，以适应起重机断续工作中频繁的直
接启动。起升电动机有两种型式，ZD型为单速电机，ZDS型为双速电机，其常速和慢速之比为10:1起重机的操纵通过按动按开关(手电门)，使接触器的触点接通或切切断电动机的电源。其主回回路和控
制回路电气元件少，线路简单，使用谁护方便
5.操纵形式
(1)地面操纵:操作人员于地面控制手电门按钮，控制起重机进行吊载作业。起重机运行速度≤30m
