13.5.6 Floor Loadings

The full weight carried by the jack will act on the floor through the base of the jack and often this is a much smaller area than the load itself presented to the floor. The floor must be capable of sustaining the point loads that will be imposed by the jacks. Account must be taken of hidden hazards such as underground pipes and cables which may affect this. Consideration should therefore be given to the use of floor spreader plates. (See section 13.10 SAFE USE OF JACKS)
