Tower Cranes Grow to New Heights
In the tower crane industry, the 1950s showcased many significant milestones in tower crane design and development. There were a range of manufacturers were starting to make more bottom slewing cranes which had telescoping mast. These types of machines dominated the construction industry for both apartment block and office construction. Lots of of the top tower crane manufacturers discarded the use of cantilever jib designs. As a substitute, they made the switch to luffing jibs and in time, utilizing luffing jibs became the standard practice.
Within Europe, there were major improvements being made in the design and development of tower cranes. Normally, construction locations were constricted areas. Depending on rail systems to transport a large number of tower cranes, became too costly and difficult. A number of manufacturers were offering saddle jib cranes that had hook heights of 262 feet or 80 meters. These types of cranes were equipped with self-climbing mechanisms that allowed parts of mast to be inserted into the crane so that it can grow along with the structures it was building upwards.
These particular cranes have long jibs and can cover a bigger work area. All of these developments led to the practice of erecting and anchoring cranes in a building's lift shaft. Then, this is the technique that became the industry standard.
The main focus on tower crane design and development from the 1960s began on covering a higher load moment, covering a larger job radius, faster erection strategies, climbing mechanisms and technology, and new control systems. Additionally, focus was spent on faster erection strategies with the most important developments being made in the drive technology department, amongst other things.
