Lifting system, which use what is in the final Assembly of structures transportation systems for adjusting the height may be, for example, designed in such a way that has multiple poles, each of which is placed in the bearing receiving device. Each bearing rests on a bearing surface. To make adjustment on the height of the bearing surface rises or falls.
Thus there are mainly the following issues:
First, the lifting system should provide for the possibility of a perfect installation in horizontal or vertical adjustment within a few millimeters or centimeters.
Secondly, structures, transportation systems are bulky and heavy, so lifting systems must meet the highest mechanical requirements.
Thirdly, lifting systems need to learn quickly and easily and quickly operated. That is, production and final Assembly conveyor systems can be highly rationalized, when it is produced on the production line. This production line contains several spreads, which, one after another, pass structure of transportation systems and at the same time maintained. At each installation site during the installation phase are specific to a given site installation activities. At the end of the maximum synchronous ongoing installation phase patterns also transport the existing systems in the process of transporting phase delivered accordingly, to the next Assembly station, and under optimum conditions of production and transportation of all structures transportation systems should be as synchronously. Obviously, fast service lifting systems greatly reduces the time manipulation.
Fourth, the lifting system should be inexpensive, because you have a large number of, namely several lifting systems for each installation site.
