manhole cover testing machine

1000KN computer control manhole cover compression testing machine

1000KN computer control manhole cover compression testing machine
1. the main purpose of the equipment:
 Microcomputer controlled electro-hydraulic servo manhole pressure tester to detect the type of manhole cover:
a. Steel fiber concrete inspection covers for inspection of under ground facilities in airport aprons, port terminals, urban roads, highways, motor vehicles that may be driven or parked
b. Steel fiber reinforced concrete inspection covers for non-motorized vehicles such as green belts and parking spaces for site inspection wells
c. Non-pressure-bearing FRP communication manhole covers and other roads and polymer-based composite manhole covers for non-vehicle travel areas
