【Scope of Application】

It is used for the assembly tolerance and waterproof performance test in the field of bridge expansion devices. It has two functions of compression and drawing. It can push and pull the expansion device horizontally, and can simulate the actual stress state of the expansion device in the highway bridge. It can be used for single Testing of specimens such as slot modulus telescopic devices and multi-slit modulus telescopic devices.
