What is the maximum local concentrated load that a cast iron fixed disc can withstand?

The local concentrated load-bearing capacity of a cast iron fixed plate has no fixed value and is entirely dependent on its specific specifications,internal rib structure,and manufacturing quality.The most reliable data must come from the technical parameter table provided by the manufacturer,which should clearly indicate the"maximum allowable concentrated load"or"point load"value(usually in tons or kilo-newtons).This is the only safe basis,and it is important not to estimate it yourself.

Its bearing capacity is primarily influenced by three major factors:structurally,the cross-shaped ribbed slab is superior to the well-shaped one,and significantly better than the honeycomb type;the thicker the panel,the stronger its resistance to indentation;the bearing capacity is strongest when there is main reinforcement directly beneath the point of load application,and weakest in the unreinforced area at the center of the panel.Additionally,the larger the contact area of the loading pad,the lower the pressure,which is more beneficial for protecting the surface of the fixed platter.

In practical use,if accurate data is not available,one must adopt a conservative approach:avoid heavy hammering or applying extreme loads to very small areas(such as using sharp corners)in non-ribbed areas.For heavy concentrated loads,it is essential to use large-area pads to distribute the pressure,and try to place the workpiece at the intersection of ribbed areas or near the edge of the platform(with side wall support).To ensure safety and accuracy,consulting the manufacturer is an essential step when dealing with critical heavy loads.
