A risk assessment for a crane lift will often highlight the need to have the ground that the crane will sit on assessed for its ability to safely sustain the pressures the crane will exert during lifting. It is industry standard to use data from the plate bearing test to achieve this and we are experts in providing it! 

 

Normally during the test the top level ground surface will be pressurised to a level well in excess of the crane's calculated ground bearing pressure and the resultant settlement of the ground under the test rig will be measured. We can advise on significant test details such as the diameter of the test plate to be used. 

 

We can test to a large variety of pressures including those in excess of 100 tons per metre square. For construction of new crane hardstanding we can provide CBR test values at formation level, often used to determine the thickness required of build up.
