At the time of installation of machinery and equipment, because of human error or inevitable lifting equipment companies, equipment installation accuracy is always a slight deviation when the device is installed, only the following requirements in line with the requirements of the deviation can be ignored. 1, can compensate for the course deviation caused by wear and tear; 2, so that smooth rotation; 3, the relevant parts can be beneficial connections with; 4, can compensate for the deviation force or temperature changes caused by post; 5, do not increase in power consumption; 6, so that the smaller parts under load force; 7, will help improve the accuracy of the workpiece to be indigenous lifting process equipment handling lifting crane hoisting that modern unconventional called, is the result. lifting equipment for objective reasons, such as the venue is small, the mechanical properties of the existing crane can not meet the practical needs of the project and other reasons, can not use the lifting machinery lifting process requires the use of simple tooling equipment, manpower and other equipment through the application process to complete lifting unconventional lifting a series of relatively low efficiency of the activity, we usually called unconventional lifting (indigenous lifting).
