Answer

Most boom trucks have limited rotation (typically 400° or less), whereas hydraulic truck cranes typically provide full 360° continuous rotation.

Question 4

Which crane is most suitable for erecting precast concrete panels in a confined urban lot where surrounding buildings restrict swing radius?

Accepted Answer

Luffing jib tower crane

Answer

Luffing jib tower cranes raise and lower the jib to vary radius, minimizing the swing arc and making them ideal for congested urban sites with restricted airspace.
