Welcome to Ji'nan Bojian Testing Machine Co., Ltd.

The spring hanger testing machine is designed and manufactured for spring hangers and hangers in accordance with the relevant national standards of springs and spring hangers. It is suitable for testing the performance of various large springs, such as variable spring support hanger, constant force spring support, spring, spring, spring, spring, and disc spring. It is the first choice for spring manufacturers, spring use units and major inspection organizations.

The spring support hanger test machine can automatically complete the whole cycle test process of spring by microcomputer control. It can also determine the parameters of the spring separately, and can print the test report. Users can adjust the testing procedures according to actual needs, and the operation is simple and convenient.

The constant force spring support hanger is used to bear the weight load of the pipe, and its bearing capacity does not change with the change of the vertical displacement of the pipe at the point of the branch.

Variable support frame: also called a variable force support hanger, which is used to withstand the weight load of the pipe, and its bearing capacity changes with the vertical displacement of the pipe at the point of the supporting point.
