hehe simple...
bitaw akong papa CONSTRUCTION project lead...
A bigger crane can be erected in the building coz they use a smaller portable crane to piece together the bigger crane.
then as the building goes higher...
or as the blue print states to add more floors in the building...
cranes are made suitable to bring more heavier equipment...
the heavier the equipment use in the building...
the bigger the cranes are made...
