i own machine shop in india i am plaining for cnc m/c i short listed two machine one hass and campro from taiwan

i would like to know why it like that
will axis motors play any role in this
hass machine weight is 3357 kg and it's max weight on table is 1361 kg. Model VF-1
In Campro case, the machine weight is 3300 kg, but the table load capacity is only 300 kg.
Why is this?

I presume it is because of the axis motor power, hence the question..
