Maximum goods lift limiting method and system for forklift

Abstract

The invention discloses a maximum goods lift limiting method and system for a forklift. The maximum goods lift limiting method for the forklift comprises the steps that the oil pressure value, acquired in real time, of a lifting oil cylinder is substituted into an established first linear relation model, so that the weight of goods lifted currently is obtained; the acting force, acquired in real time, applied to a portal by an oblique oil cylinder is substituted into an established second linear relation, so that the current load center distance is obtained; the current lifting height which isacquired in real time and the current load center distance which is acquired in real time are substituted into an established multiple regression model, so that the maximum lifted goods weight corresponding to the current lifting weight and the current load center distance are obtained; and the current lifted goods weight is compared with the maximum lifted goods weight, and corresponding actionis conducted according to the comparison result. The influence factors of the maximum lifted goods weight include the lifting height and the load center distance, lifting is limited when the lifted goods weight exceeds the maximum lifted goods weight, and thus overload operation and accidents can be effectively prevented.

Description

technical field [0001] The invention relates to the field of forklift safety, in particular to a method and system for limiting the maximum cargo lifting of a forklift. Background technique [0002] Forklifts are industrial handling vehicles that can load and unload palletized goods, stack them and transport them over short distances. Because they greatly improve work efficiency and reduce the labor intensity of workers, they have been more and more widely used. During the process of stacking goods by forklift, due to the different lifting heights of the mast, its carrying capacity is different. The higher the lifting, the weaker the carrying capacity. If the weight of the forklift truck exceeds the maximum lifting weight of the cargo that the fork’s current lifting height and the current load center distance can carry, the forklift will be in danger during use. However, currently in the operation of forklifts, there are basically no protective measures for the materials be...

AI Technical Summary

Problems solved by technology

However, currently in the operation of forklifts, there are basically no protective measures for the materials being forked by the forklifts. When the weight of the goods is heavy, and the lifting height of the mast is high and the inclination angle is large, overloading often occurs and the materials are overturned. or fall, and in severe cases, the entire forklift will also overturn, which will not only bring huge loss of goods and property, but also bring great personal safety hazards to operators
