价 格:面议

1、设备的进场、上排:在各项准备工作完全做好的情况下,再开始组织设备的进场、上排和吊装工作。

2、吊装前的准备工作:设备在吊装前,必须做好全面仔细的检查核实工作。检查设备安装基准标记、方位线标记是否正确;检查设备的吊耳是否符合吊装要求。

3、吊装索具的系接:主要包括滑车挂上吊耳、电动卷扬机的拉力试验和方位调整、拖排牵引和拖尾系统的设置等。

4、试吊:试吊前检查确认;吊装总指挥进行吊装操作交底;布置各监察岗位进行监察的要点及主要内容;起吊放下进行多次试验,使各部分具有协调性和安全性;复查各部位的变化情况等。

5、吊装就位:由总指挥正式下令各副指挥,检查各岗位到岗待命情况,并检查各指挥信号系统是否正常;各岗位汇报准备情况,并用信号及时通知指挥台;正式起吊,使设备离开临时支座500—800mm时停止,并作进一步检查,各岗位应汇报情况是否正常;撤除设备支座及地面杂物,继续起吊。

大型吊车租赁:大型吊车是为完成某种特定任务而研制的专用起重机。为处理交通事故用的公路清障车等,均属此类。起重机的工作类型:指起重机工作忙闲程度和载荷变化程度的参数。工作忙闲程度,对起重机来说,就是指在一年总时间内,起重机的实际运转时数与总时数之比;对机构来说,则是指一个机构在一年时间内运转时数与总时数之比。在起重机的一个工作循环中,机构运转时间所占的百分比,称为该机构的负载持续率,用JC表示。

我公司出租大型吊车,产品质量有保证,效率高,能节省你的时间。

履带吊是履带起重机的简称,是一种下车地盘是履带行走机构,靠履带行走的吊车。优点是 起重量大,可以吊重行走。具有较强的吊装能力。

轮胎吊是利用轮胎式底盘行走的动臂旋转起重机。 轮胎吊是把起重机构安装在加重型轮胎和轮轴组成的特制底盘上的一种全回转式起重机,其上部构造与履带式起重机基本相同。汽车吊也是轮胎吊的一种。优点是车身短,作业移动灵活,工作效率高。

我们常遇到设备的装、运、安装等项工作,不论是采用扒杆起吊或是机械吊装都应注意以下几点:

(1)土法施工用的滚动法装卸移动设备,滚杠的粗细要一致,年度应比托排宽度长50cm,严禁带手套填滚杠。装卸车时滚边的坡度不得大于20°,滚道的搭设要平整、坚实,接头错开,滚动的速度不宜太快,必要时要用溜绳。

(2)在安装过程中,如发现问题应及时采取措施,处理后再继续起吊。

(3)用扒杆吊装大型塔类设备时,多台卷扬机联合操作,必须要求各卷扬机的卷扬速度大致相同,要保证塔体上各吊点受力大致趋于均匀,避免塔体受力不匀而变形。

(4)采用回转法或扳倒法吊装塔罐时,塔体底部安装的铰腕必须具有抵抗起吊过程中所产生水平推力的能力,起吊过程中塔体的左右溜绳必须牢靠,塔体回转就位高度时,使其慢慢落入基础,避免发生意外和变形。

(5)在架体上或建筑物上安装设备时,其强度和稳定性要达到安装条件的要求。在设备安装定位后要按图纸的要求连接紧固或焊接,满足了设计要求的强度和具有稳固性后,才能脱钩,否则要进行临时固定。
