Man Hole Cover Testing Machine

Product Description

The manhole cover testing machine is design as per is 12592. The machine is capable of measuring following.

• Load test
• Permanent set (displacement)

The machine will consist of two units.

• Pumping unit
• Load frame

Pumping unit:

• The pumping unit will work on single phase,220 volts.
• The pumping unit will be compact, filled with hydraulic oil.
• The pumping unit will have two valves.
• Pressure release valve
• Pressure control valve
• The pressure release valve will facilitate building and release of the pressure.
• The pressure control valve will allow to control the pace rate of the machine from 2 kN / sec to 10 kN / sec
• The pumping unit will have digital read out, showing actual load, peak load and permanent set .
• The pumping unit will be equipped with pressure sensor to give accurate reading of load in kN.
• The accuracy of the pumping unit will be + or  1% and will give  resolution in 0.1 kn.   
• There will be sensor to find out the  permanent set of deformation in the manhole cover.
• The pumping unit will have over load protection which will trip the machine in case of over load.
• The machine is able to conduct 5 cyclic load test manually for permanent set.
• The machine is able to hold the load for 30 sec to conduct the load test.

Load frame :

• The load frame will be fully welded which will be able to take a load of 500 kN.
• The load frame will able to accommodate manhole cover of 1200 mm  x 1200 mm size.
• The machine will be supplied with the plate to place the manhole cover. The plate will be hardened and properly shaped.
• The hydraulic jack of the machine will be provided on the top of  the machine which will be able to slide up-down with the help of  the handle. The ram dia of the jack will be 120.00 mm
• The load frame will be connected to the pumping unit with the help of hose pipe.
• The machine will be supplied with operation manual and calibration certificate.
