manhole cover testing machine

600KN 1000KN computerized manhole tops and gully tops compression and fatigue testing machine

Description
600KN 1000KN computerized manhole tops and gully tops compression and fatigue testing machine
1. Introduction of testing machine
The manhole cover compression testing machine can be used to test the compression properties( permanent set, load bearing capacity,fatigue test) of cast iron manhole cover, composite material manhole cover, and steel reinforced concrete.






The manhole cover compression testing machine adopts computerizing, high precision electro-hydraulic servo valve to drive precise hydraulic cylinder and then realize the auto control to the test force, displacement, and deformation, etc.
