15. Host size: 2000mm×1500mm×1500mm (Length×Width×Height)

16. Host weight: 3500Kg

1. The host adopts a high-rigid structure to ensure safety during the test.

2. Place the loading cylinder on the top, and the workbench height is 300mm, which is easy to pick up and put up the manhole cover specimen.

3. A ball-hinged connection is adopted between the rigid pad and the piston push end to ensure the authenticity of the measured bearing capacity.

4. The oil cylinder and the piston are sealed with special materials to achieve the effects of high sealing, low friction and long life.

5. Use professional test oil pump motor set, low noise and long life.

6. Choose an ultra-fine oil filter to ensure the cleaning of the oil circuit system and ensure the long-term work of the control actuators.

7. The digital display table displays, displaying the current force value, peak value, etc. in real time.
