1. TQS Bridge Expansion Joint Test System Function: 1. The  bridge expansion joint test system is referred to as the Bridge Expansion Joint Tester, which can detect the expansion joints specified in the JT/T327-2 016 " General Technical Conditions for Highway Bridge Expansion Joints " standard Items requiring overall performance. Displacement uniformity test and friction resistance test of expansion device under normal state and various complex states, realizing the overall mechanical performance test of bridge expansion joint device. With safety protection device, fault alarm, overload alarm, over-limit and other protection functions.

2. This device is a unilateral movable type, and can realize tension and compression tests after dislocation in three directions. 3. This device adopts full hydraulic control (except for the analog brake system), and the corresponding actions can be controlled individually or linked by program. 4. The device is equipped with a simulated loading system, which can load the most dangerous sections of the center beam and cross beam. 5. The device is equipped with an analog braking system, which can measure the horizontal displacement value of the center beam and the stress of the corresponding linkage mechanism under the simulated braking state. 6. The control system of this device can realize the functions of collecting, processing, displaying and printing the detection data. 7. This device is equipped with an alarm and protection device for over-limit values to ensure that the detection test is carried out in a completely safe state. 2. Product parameters of the test system for bridge expansion joints : 1.
