1. whether it has an independent power organization and electrical system?
200吨四柱液压机，是属于中型液压机一类别，据这方面专业技术人员介绍，它是有独立的动力组织和电器体系，并采用按钮集中操控，可进行适当调整。在操作方式上，是有自动、半自动和手动这三种操作方式。
What tools are used to tighten the 2. column nuts? What are the instructions on its composition?
These two problems, the column nut of the 200-ton four-column hydraulic press, are tightened by using a crescent wrench.
The hydraulic transmission system includes power organization, control organization, execution organization, auxiliary organization and operation medium composition. In the power organization, the oil pump is usually selected as the power organization, usually a product oil pump. In order to meet the requirements of the speed of the tissue movement, one or more oil pumps can be selected. In addition, in the hydraulic control, the cartridge valve integrated system can be selected, because it has the advantages of reliable action, small hydraulic impact and long service life, but hydraulic control can also be used.
Is there any difference between the upper jacking cylinder and the lower jacking cylinder of the 3?
The upper top cylinder and the lower top cylinder of the 200-ton four-column hydraulic press, if you compare the two, the conclusion is that there is a big difference between the upper top cylinder and the lower top cylinder, and the difference between the two, Specifically, the upper top cylinder refers to the top from bottom to top, and the lower top cylinder refers to pressing down from top to bottom, which are two different concepts.
How is 4. weight calculated?
计算200吨四柱液压机的重量，其可以计算大体重量，如果是三梁四柱液压机，其要考虑到机身重量，以及液压机吨位、行程、开口或闭口高度、工作台面积、滑块速度及主缸布置等这些参数。而且，有可能要求在方案设计过程中估计重量。
