All over the world a growing number of midtown high-rise projects above 300 metres are under development. To shorten construction time and improve build quality, larger precast and prefabricated modules are becoming common. As these modules get larger and become more complicated their weight rises dramatically. Prefabricated pre-finished volumetric construction (PPVC) is particularly popular in Asia.

Rough terrain cranes could be described as pioneers of the jobsite. They are often the first cranes there, equipped to travel over rough ground, leading the way for other types of cranes and equipment to follow. This pioneering spirit can also be seen in the approach rough terrain crane manufacturers take, breaking new territory with ever higher lifting capacities, longer booms, smaller dimensions, greater safety, and more advanced control systems. The boundaries are being redefined all the time. Continue reading “Pioneers: rough terrain cranes”
