The most critical 'core joint' of a bridge - the bridge bearings. It is hidden between the beam slab and the bridge pier, seemingly inconspicuous, but it plays a core role in bearing pressure, buffering vibration, adjusting displacement, and offsetting deformation. All stresses caused by vehicle compaction, temperature changes, wind vibrations, and foundation settlement must be absorbed and shared by the supports. If the support is stable, the bridge beam is stable; If the support is excellent, the road and bridge will be safe.
Therefore, the mechanical performance testing of bearings is an insurmountable and rigid standard in the quality inspection process of road and bridge engineering. To accurately verify the quality of bearings, a professional, precise, and compliant bridge bearing compression shear testing machine is an essential equipment for major testing centers, bearing manufacturers, and engineering quality inspection departments.
Why is it necessary to use professional compression and shearing equipment for support testing?
In the actual service process of bridges, bearings are never in a single stress state.
In daily traffic, it not only has to withstand the huge vertical pressure of the upper structure of the bridge, but also has to resist the horizontal shear force caused by vehicle driving, wind, and temperature expansion, while adapting to the slight angular deformation of the bridge.
Ordinary single function testing machines can only test compressive or shear performance separately, and cannot simulate real composite stress conditions. The testing data is one-sided and difficult to meet the national standard testing requirements, let alone predict the actual service life and safety performance of the support.
The bridge bearing compression shear testing machine completely breaks the limitation of single detection, perfectly reproduces the real stress environment of the bridge, realizes the integrated detection of vertical pressure bearing, horizontal shear, and corner testing, comprehensively restores the real working state of the bearings, and makes the testing data fit the actual engineering situation.

03 Core Hardcore Configuration, Accurately and Efficiently Handle Quality Inspection Work
Compared to traditional testing equipment, the new generation of electro-hydraulic servo bridge support compression shear testing machine has achieved comprehensive upgrades in accuracy, stability, and intelligence, completely solving the pain points of large testing errors, cumbersome operations, inaccurate data, and complex reports in traditional testing.
🔹 Electro hydraulic servo closed-loop control, achieving full precision
Adopting a high-precision electro-hydraulic servo control system with dual closed-loop regulation of pressure and displacement, the loading is smooth and the response is sensitive. It can achieve various test modes such as uniform loading, pressure holding and stabilizing, and graded loading. Effectively avoiding pressure fluctuations and data drift issues, the detection accuracy far exceeds industry standards, and small deformations and stress changes can be accurately captured.
🔹 Integrated composite test, one machine for multiple purposes
Without the need to replace molds or split the testing process, a single device can independently complete various tests such as single compression, single shear, compression shear composite, and corner coupling. Completely bid farewell to the tedious process of rotating multiple devices for testing, significantly saving equipment procurement costs and laboratory space.
🔹 Intelligent fully automated operating system, worry free and efficient
Paired with specialized industrial measurement and control software, the operating interface is simple and intuitive. Support one click start of experiments, automatic data collection, real-time curve display, and dynamic recording throughout the entire process, without the need for manual monitoring. After the experiment is completed, a standardized testing report can be automatically generated, and the data can be archived, exported, and traced, greatly reducing manual calculation errors and improving the efficiency of quality inspection work.
🔹 Sturdy body structure, stable and durable
The whole machine is made of thick and high-strength steel structure welded together, with sufficient rigidity and small deformation. It is not easy to deform during long-term high load loading tests and has a low failure rate. Equipped with professional shock absorption, noise reduction, and voltage stabilization design, the equipment operates stably and has a long service life, suitable for high-frequency and normalized laboratory testing work.
