Function:
This 600KN 60Ton computer control hydraulic servo well lid compressive strength testing machine is mainly used to do the compressive strength test and deformation test for various types of manhole covers, like cast iron manhole cover, recycled resin manhole cover, composite manhole cover, ductile iron manhole cover, insulation material manhole cover, rubber manhole cover etc. Its detection accuracy is better than Class 1.

It meets the standard: GBT23858-2009, CJ/T3012-93,JC/T889-2001,CJ/T121-2000,CJ/T948-2005 etc.

Character:

1. The mainframe adopts a high rigidity structure to ensure safety during the test.
2. The loading cylinder is placed on the bottom, and the height of the working table is convenient to take the manhole cover.
3. The special sealing material is used between the cylinder and the piston to achieve high sealing, low friction and long life.
4. The use of professional test oil pump motor unit, low noise and long life.
5. Use ultra-fine oil filter to ensure the cleanness of the oil circuit system to ensure long-term operation of the control actuator.
6. This testing machine is controlled by computer system, no oil valve, it can realize the closed-loop control, constant force loading, improves the test precision. It also has the force holding function.
7. During the testing process, the software interface can display the load force, load peak, load speed, test time in real time. You can see the force curve, save test data, print the test report.
