Description of Product
The MHC-1000A electro-hydraulic servo compression tester is high-precision test equipment designed for manhole cover testing. Powered by a hydraulic station, it applies electro-hydraulic servo control and computerized data acquisition to complete material performance tests.
It assesses the bearing capacity of manhole covers made from different materials, including residual deformation and applied test load. The machine supports closed-loop control modes such as loading at a constant speed and deformation at a fixed rate, and it can automatically calculate the key performance parameters of specimens.

Features
- Equipped with high-seal single and double acting hydraulic cylinders to ensure high efficiency and long service life.
- The main frame is built with high-strength steel plates, which provides great rigidity and stable overall performance.
- A high-precision digital hydraulic sensor serves as the load measurement component. It delivers precise readings, consistent repeatability and stable long-term operation.
- All electric signals generated during loading are captured and processed by specialized PC software.
- The hydraulic oil source adopts servo closed-loop control. It consists of digital servo valves, motors with steady torque and speed, and high-precision valve assemblies, featuring fast response and high sensitivity.
- The system continuously monitors load and deformation data. With tracking and adjustable functions, it enables fully automatic and precise test control.
- A high-speed Ethernet port is used for data communication between the measurement-control unit and computer.
- Test records are saved in a standard database for easy access. Operators can re-analyze test data and curves, magnify partial graphics and modify data. The system automatically calculates various mechanical indicators of materials, and prints complete test reports and curves.
- Multiple safety protection functions are available: overload protection for force, overspeed protection of force channel and stroke limit protection.
- Users can program the measurement and control system to fit different test scenarios, including cyclic loading and load retention tests.
