Cranes Enabled Faster, Safer Construction of Tall Buildings
Not all tower cranes are created equally: Some resist fatigue, lift and cost more than others. But all are built under similar engineering principles linked by a common history.
While most mobile cranes evolved from steam shovels, all cranes harken back to the earliest lifting devices, which were simple derricks and gantries fitted with gears, ropes and other tackle used by the Ancient Egyptians, Greeks and Romans to move heavy stones needed to build structures. It wasn’t until the first tall-building boom at the turn of the last century that tower cranes as we know them began to arrive.
