Tower cranes have become an essential tool in the construction industry. They are used to lift heavy materials and equipment to great heights for the purpose of construction or demolition of buildings. As impressive as they are, one question that often arises is, how do tower cranes go up?
The Assembly Process
Before a tower crane can start working, it must be properly assembled. This process is done by using a smaller mobile crane to lift the parts of the tower crane up. The smaller crane will start by lifting up the base of the crane and securing it to the ground. Then, the tower section will be lifted by the mobile crane and bolted onto the base. This process is continued until reaching the desired height of the crane.
Tie-in Process
Once the tower crane has been assembled, it must be secured to the building. To do this, the crane assembly team will attach the crane to the building using steel ties. The weight of the tower crane is very heavy, and these ties are essential for stabilizing the crane to prevent it from tipping over in high winds or when carrying heavy loads.
The Climbing Process
Once the tower crane is securely attached to the building, it’s time to climb. The process of climbing involves adding additional tower sections to the top of the crane. This is done by using hydraulic jacks to lift the crane off the ground while the tower section is added. The process is repeated until the crane reaches its desired height.
Raise Climbing Process
A raise-climbing crane is a type of tower crane that can climb up a building as the building is being constructed. It features a special mechanism that enables it to climb up the building by effectively lifting itself up with hydraulic jacks. This type of tower crane can only be used for buildings with a consistent shape and height. This method is popular in building construction as it eliminates the need for dismantling and reassembling the crane at every new level.
Conclusion
In conclusion, the process of raising a tower crane involves various stages, which require skilled crane operators and a sound understanding of crane mechanics. The process is highly safety-sensitive and requires a strict adherence to government regulations and guidelines. Understanding how tower cranes go up can give a better appreciation of the importance of these machines in the construction industry.
