1.Product name:computerized manhole cover compression testing machine
2. Introduction of testing machine
The manhole cover compression testing machine can be used to test the compression properties 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.
3.test standard
BS EN 124 Gully tops and manhole tops for vehicular and pedestrian areas-Design requirements, type testing, marking, quality control
