Tower Cranes Grow to New Heights

In the tower crane industry, the 1950s featured numerous significant milestones in tower crane design and development. There were a variety of manufacturers were beginning to make more bottom slewing cranes which had telescoping mast. These kinds of machines dominated the construction business for office and apartment block construction. Lots of of the leading tower crane manufacturers didn't utilize cantilever jib designs. In its place, they made the switch to luffing jibs and in time, using luffing jibs became the regular practice.



Manufacturers based in Europe were also heavily important in the design and development of tower cranes. Construction areas on the continent were usually tight places. Relying upon rail systems to transport several tower cranes, became too costly and inconvenient. Some manufacturers were offering saddle jib cranes that had hook heights of 262 feet or 80 meters. These kinds of cranes were outfitted with self-climbing mechanisms that enabled parts of mast to be inserted into the crane so that it can grow along with the structures it was constructing upwards.



These particular cranes have long jibs and can cover a bigger work area. All of these developments precipitated the practice of erecting and anchoring cranes inside the lift shaft of a building. Afterwards, this is the method that became the industry standard.



From the 1960s, the main focus on tower crane design and development started to cover a higher load moment, covering a larger job radius, climbing mechanisms and technology, faster erection strategies, and new control systems. Additionally, focus was spent on faster erection strategies with the most significant developments being made in the drive technology department, amongst other things.
