Ancient to Present.
The crane has been around as long as man has been on the Earth, Stone Henge in the United Kingdom, the Pyramids of Egypt and the Great wall of China could not have been constructed without some form of crane or pulling device.
Slaves and animals too played an essential part, because the people who designed and built these monuments where part of high society and part of powerful empires. Today we take the crane and various lifters for granted, not high rise can be built without them being built into the structure of the towers in New York, Dubai and London.
Today there are a variety of types available to do different types of lifting, some of this being the recovery of heavy loads or the moving over structures into confined spaces. This is were the telescopic cranes have come into their own right.
