General Introduction
CW series Compressiong Testing Machine can determine static compression and dynamic fatigue load performance for manhole covers, well shutters, cover plates, well grates, shutter grates, gully tops used in green belt, tree lawn, sidewalk, pavement, motor way, bicycle lane, parking lots, wharf, airfield runway, highway, citizen zone etc., .
Conform with international standard of EN 124:1994 Gully Tops and Manhole Tops for Vehicular and Pedestrian Areas-Design Requirements,Type Testing,Marking,Quality Control). GB/T 23858:2009, GB/T GB26537-2011 etc.,
Key Features
All gully tops and manhole tops will be submitted to the following test:
1. Measure the permanent set of the cover or grates after the application of 2/3 of the stipulated test load (according the Class of the cover and Clearance opening).
Speed 1kn/s ~ 5Kn/s load the force on cover to 2/3 of test load, then release the load, repeat 5 times, check the final reading of residual deformation.
2. Apply the test load on the sample. Keep at least 30 seconds, Observe if there any crack, damage.
1. High stiffness, high stability dual columns frame, with big stiffness to ensure the test accuracy.
2. Oil cylinder at topside, large stroke 200mm piston, easy and suitable for various kinds test sample. high speed, high frequency.
3. Wide effective test space 1200*1400mm, easy for sample install and uninstall.
4. Movable residual deformation measuring device, suitable for different size.
5. Various specification of test blocks, suitable for different size test sample.
6. High accuracy load cell to measure the load.
7. Overload protection, limitation switch function, Over voltage, over current, emergency stop etc.
1. Computer realtime control and display test process, curve. Curve can free zoom in zoom out.
2. Data automatically collection, analysis; automatically calculate and display test result, easy for data storage, report printing, MS excel report function.
3. Friendly software interface, powerful edit function, different control mode smoothly switch.
4. Load control, load holding, stress, strain, cycle control, self-edit program control etc., multiple test control mode.
5. English version software, and English Win7 system.
6. After test finish can automatically piston can back to original position.
