How tower cranes climb
Floor-climbing
Tower crane climbs us along the number of floors constructed.
タワークレーンが上る時
Assemble a tower crane to construct several floors.   The body is to be fixed on the higher floor and hydraulic cylinder pulls up the mast.   The bottom of mast is to be fixed on the higher floor and then the body climbs along the mast.   Tower crane repeats this process over and over just as a measuring worm. This is called “floor-climbing”.
