The rear tensioning device of the rear beam is an indispensable important component of the carriage winding system. The existing tensioning device of the lying-flat bracket trolley winding system has some shortcomings in terms of production, transfer work, assembly, and maintenance. Based on these shortcomings, in order to reduce product cost and increase efficiency, and improve product quality, the existing flat tensioning device was innovatively optimized. The innovative and optimized flat-laying tensioning device has good manufacturability, easy production, no deformation during transportation, and convenient installation and maintenance, which greatly saves design, process, production, assembly and maintenance time and costs. For renewal projects, the interchangeability of key parts is ensured, the cost of spare parts production is reduced, and it is conducive to user acceptance and promotion.

The rear girder tail tightening device is an essential and important component of the carrier car winding system. The existing flat-bed carrier car winding system tightening device in the production, transfer work, assembly, maintenance and other aspects have some shortcomings. Based on these deficiencies, in order to reduce the cost of products efficiency, improve product quality, the existing flat-bed zhang device for innovative optimization. After the innovation and optimization of the flat-bed opening device process is good, easy to make, transfer does not deform, installation and maintenance and other convenient, greatly saving the design, process, production, assembly and maintenance time and cost. For renewal items, to ensure the interchangeability of key components, reduce spare parts production costs, conducive to user acceptance and promotion.

The rear girder tail tensioning device is an essential and important part of the trolley winding system. There are some deficiencies in the production, transfer, assembly, maintenance and other aspects of the existing tension device of the trolley winding system. Based on these shortcomings, in order to reduce the cost, increase efficiency and improve the quality of products, the existing lying down tensioning device is innovated and optimized. After innovation and optimization, the lying down type tension device has good processability, simple production, no deformation in transportation, convenient installation and maintenance, which greatly saves the time and cost of design, process, production, assembly and maintenance. For the renewal project, it ensures the interchangeability of key parts, reduces the production cost of spare parts, and is conducive to the acceptance and promotion of users.<br>
