Description

Technical Field

[0001] This utility model relates to the field of stacker trucks, and in particular to a stacker truck lifting limit device. Background Art

[0002] Stacker cranes, also known as stacker units, are the most important lifting and transport equipment in automated warehouses and are a hallmark of automated warehouses. The main function of stacker cranes is to move back and forth within the aisles of the automated warehouse, storing goods located at the aisle entrance into the racking compartments, or retrieving goods from the racking compartments and transporting them to the aisle entrance. With the development of computer control technology and automated warehouses, stacker cranes are being used more and more widely, with better technical performance and greater height. Today, the height of stacker cranes can reach 40 meters. In fact, if not limited by warehouse building and cost, the height of stacker cranes can be even higher.

[0003] However, existing stacker cranes lack the ability to limit and warn of height increases. In actual operation, they are limited by the height of goods and warehouses. If the height exceeds a certain limit, safety accidents are likely to occur, affecting the safety of goods stacking and transportation. At the same time, existing stacker cranes also lack the ability to buffer the rise of the forks. When the forks rise rapidly, they are more likely to collide directly with the stacker truck, affecting the stability of use. Therefore, we need to upgrade and modify the existing technology to overcome its problems and shortcomings. Utility Model Content
