Weight: the weight of underground section without load and ballast with longest jib and maximum free-standing height.
The construction of fixed foundations directly affects the safety of tower cranes, and we must not take it lightly or cut corners, otherwise it will cause serious consequences.
Major equipment and personal injury accidents bring unnecessary losses and troubles.
Before installing the tower crane, users and installation units should consider the form of the purchased tower crane, the various requirements and data provided below, Pre calculate the strength of the concrete fixed foundation and the bearing pressure of the foundation for the tower crane, and determine the construction method.
When selecting the installation location of the tower crane, the first consideration should be the convenience of installation and disassembly of the tower crane (the side of the tower body with steps should be aligned with the building).
When the building is vertical, consider the maximum efficiency of the tower crane. If the height of the building exceeds the independent height, it should also be considered as much as possible.
Our city skylines would be completely different without these tower cranes, as the cranes, chains, wires and ropes on these machines make construction work that was previously considered dangerous safer and more efficient. Whether you're building bridges, railways, or other structures, there's a specific tower crane that can get the job done.
