What are the two main types of tower cranes?
Recall the differences based on their rotation mechanisms.
Why are counterweights important for tower cranes?
Think about what happens when loads are lifted.
What mechanism allows tower cranes to rotate?
Think about crane movement and flexibility.
True or False: Bottom slewing cranes can work at higher elevations without stabilization.
Recall the design and purpose of bottom slewing cranes.
A top slewing crane has a maximum lifting capacity of 1500 kg at a radius of 10 meters. Calculate its capacity at a radius of 18 meters given it follows a linear reduction model.
Remember how stability decreases with increasing radius.
Design a basic framework for erecting a bottom slewing crane focused on minimizing hazards in a public environment.
Think about the challenges posed by rotating freedom.
