Definitions
- the present invention relates to a folding device for lifting "so in construction of large metal containers, and a removable accessory applicable thereto, whose features facilitate construction procedures by reducing construction times and costs.”
- Patent ES 2 211 268 Bi (Cari ⁇ ox) of 03/08/2005 describes a central unit for hydraulic systems of this type
- patent ES 2 213 436 Bi (Cari ⁇ ox) of 06/29/2005 shows a system of hydraulic lift for the assembly and disassembly of vertical tanks, where hydraulic jacks are divided into independent drive groups for optimum control of the verticality of the structure.
- the lifting device must be able to hold or securely hold the structure, for which, in known technologies, accessory supports are normally welded in the structure as handles, which the jack uses as a lock or point support to support the structure during lifting. These brackets must be removed once the work is finished, which requires considerable labor and affects the finish of the work. On the other hand, the presence of the cat prevents the free work of the operators. This detail is of utmost importance in the construction of metal tanks, since it is vital to ensure the quality of welding of the layers that make up the walls of the container to ensure the structural strength of the assembly. In this case, the device that supports the structure while mounting a new ferrule prevents the use of automatic welding machines. Additionally, the device itself must be firmly located, which generally implies welding its base to the bottom of the tank, with the consequent expenditure of resources necessary to desolder it after the work is finished.
- the device of the present invention solves all these inconveniences, minimizing the temporary welds necessary for its location and allowing its overflow in order to allow improvements in the construction conditions of the containers.
