A high-rise building changes the wind direction downwards causing high-wind speed on the lower part of the building

Wind vortices tend to occur on the lower part of a high-rise building

Luffing cranes are used to ensure the jib stays within site boundaries

Hammerhead cranes are faster in operation

Hammerhead cranes are typically cheaper than luffing cranes

2-part line configuration is slower, but has higher capacity than 4-part line

Hammerhead cranes usually have lower capacity that luffing cranes

Flexibility in planning

Better speed of work
