Projeto de um sistema de nivelamento para doca em centros logísticos

Abstract

The purpose of this work was to design a leveling system that minimizes unsafe working conditions. In particular, when there are significant differences between the height of a logistics center's dock and the cargo compartment of a vehicle. The mechanism consists of an upper platform that has vertical movement, raising or lowering the load. And when the differences between dock height and cargo compartment are small, the upper platform can tilt to form a ramp between the vehicle's dock and cargo compartment. The leveling system project consisted of carrying out the product development process, having the customer's expectations as input, defining an adequate concept to the needs of the customer in question. The system was designed based on commercial vehicles and based on the NBR 8400 standard (Calculation of equipment for lifting and moving loads). In addition to the design of the structural components of the system, an analysis under the security aspects was carried out. However, the leveling system developed showed differences between the leveling systems available on the market, standing out for the leveling flexibility. Leveling was possible with vehicles whose load compartment is located 600 mm from the floor and with vehicles where the load compartment has a height of 1200 mm. This was possible because part of the leveling system needs to be 210 mm below the ground. The need to place the leveling system below the floor was not only due to the range of movement, but also to balance the internal forces of the structure. It was also necessary to develop a beam with a variable section, collaborating to achieve full movement of the system and reducing its mass. The leveling system designed does not tend to tip the forklift, however the orientation of the lifting height of the loaded load must be respected. [resumo fornecido pelo autor]
