欧式起重机与传统起重机的区别特点

欧式起重机与传统起重机的区别特点

1、从设计结构上看：①欧式起重机：主梁采用箱型梁结构，结构合理且强度更高，葫芦与主梁下翼缘结合牢固，无隐患，增大有效起升高度，从而提高了有效的作业空间，净空差最大，可达1.5米，轮压减少，承轨梁减少；②传统起重机：受限于葫芦设计，只能采用传统下置工字钢结构，结构不合理且利用率低，葫芦与主梁下翼缘结合形式导致脱离事故发生率高。2、从外观上看：①欧式起重机：外观轻巧、美观，符合现代工业审美，有效地利用

The difference between European crane and traditional crane

The difference between European crane and traditional crane

1. From the perspective of design structure: (1) European crane: the main beam adopts box beam structure, reasonable structure and higher strength, the hoist and the lower flange of the main beam is firmly combined, no hidden danger, increase the effective lifting height, so as to improve the effective working space, the maximum headroom difference, up to 1.5 meters, wheel pressure reduction, rail beam reduction;

起重机设备的性能与参数

起重机设备的性能与参数

表现起重机械基本工作能力的最主要的性能参数是起重量和工作级别。①起重量是指在规定工作条件下允许起吊的重物的最大重量，即额定起重量。一般带有电磁吸盘（见起重吸盘）或抓斗的起重机，其起重量还应包括电磁吸盘或抓斗的重量。臂架型起重机的起重量还包括吊钩组的重量。②工作级别是反映起重机械总的工作状况的性能参数，是设计和选用起重机械的重要依据。它由起重机械在要求的使用期间内需要完成的工作循环总次数和载荷状态来

Performance and parameters of crane equipment

Performance and parameters of crane equipment

The performance of the basic working capacity of lifting machinery is the most important performance parameters of the weight and work level. (1) Lifting weight refers to the maximum weight allowed to be lifted under the specified working conditions, namely the rated lifting weight. In general, the lifting weight of a crane with an electromagnetic sucker (see lifting sucker) or grab should also include the weight of the electromagnetic sucker or grab. The lifting weight of the boom crane also includes the weight of the hook group.

东北振兴可从“重工业化”寻找内生动力

东北振兴可从“重工业化”寻找内生动力

日前，辽宁省社会科学院副院长梁启东对媒体说，经济下行压力越大，越要坚定不移调结构。近一两年来，东北地区调结构取得了不小的进步，但在经济结构、产业结构、产品结构等方面仍有很大调整空间。比如，轻重工业比例仍然不合理、民营经济占比有待提高、战略性新兴产业体量依然薄弱等。  　　东北振兴需要调结构，这应该已成共识。而该如何调结构也有不少论断，比如东北经济中第三产业服务业比重太低；重工业化占经济的比重过大需

Northeast Zhenxing can seek endogenous impetus from "heavy industrialization"

Northeast Zhenxing can seek endogenous impetus from "heavy industrialization"

Liang Qidong, vice president of The Liaoning Academy of Social Sciences, recently told the media that the greater the downward pressure on the economy, the more unswervingstructural adjustment is needed. In the past one or two years, northeast China has made great progress in structural adjustment, but there is still a lot of room for adjustment in economic structure, industrial structure and product structure. For example, the proportion of heavy and light industries is still unreasonable, the proportion of the private sector in the economy needs to be increased, and the size of strategic emerging industries is still weak.
