JYAW-1200 Computer Control Electro-hydraulic Servo Manhole Cover                                          Compression Testing Machine

I Application
The machine according to EN124-1994 "Gully Tops And Manhole Tops For Vehicular And Pedestrian Areas - Design Requirements, Type Testing, Marking, Quality Control" for the bearing capacity of the well cover test. Its structural performance in full compliance with test specifications.  

II Usage and Characteristics
1, the host uses a high-rigidity structure, to ensure the safety of the test process.
2, Loading cylinder on the home, worktable height about 580mm, easy to take and put the manhole cover specimen.
3, Between the rigid padding block and the pushing end of piston uses ball hinge connection, to ensure full contact between the cover and the reaction force to ensure the authenticity of the measured bearing capacity.
4, Cylinder and piston with special materials seal, to achieve high sealing, low friction, long life effect.
5, using professional testing machine pump motor, low noise, long life.
6, the choice of ultra-fine filter to ensure that the oil system clean to ensure that the implementation of the long-term control of the work components.
7, the computer automatically controls the real-time display of current force, peak, test process information.
8, the test process real-time record test curve, high-speed sampling;
9, data, report processing functions, to provide users with a graphical report for the exclusive layout editing tools, with flexible operation, easy to learn characteristics, can easily print test curves and test values;
10, the control mode has constant speed stress, constant speed test force, test force to maintain and other control functions and test force, test curve screen display, test curve force - time curve, the control mode smooth transition.
11, the software set value automatically cleared system, eliminating human error factors such as reading meter.
12, with overload protection, when the force value or displacement beyond the rated theoretical value of the testing machine, automatic unloading or stop the test.
13, destroy load and deformation values automatically capture and print the report.
14, the deformation measured at the bottom, the data is accurate and stable.
15, the scene can be based on experimental needs, user-programmed, automatic closed-loop control, loop loading, loading speed, loading waveform.

1. Movable lifting manhole cover device. (Customer should supply models and dimensions of all kinds manhole covers.)
