Scissor cargo platform with a constant transfer ratio

Škarasti podizač s konstantnim omjerom pogonske i radne sile namjenjen je za potrebe podizanja tereta između dvije razine logističkog skladišta. Podizna platforma škarastog mehanizma ostaje horizontalna tijekom podizanja i spuštanja iste, što omogućuje sigurni transport tereta između dvije razine logističkog skladišta. Mehanizam se naziva škarasti jer se između baze i podizne platforme nalazi mehanizam sličan mehanizmu ručnih škara. Jedan kraj škara je pričvršćen za bazu, dok je drugi pričvršćen za podiznu platformu. Suprotni krajevi škara se slobodno kotrljaju po bazi i podiznoj platformi. Rad započinje uvodnim razmatranjem o vrstama podiznih platformi za različite namjene i uvjete. Slijedi pregled tržišta i razrada vlastitih koncepcijskih rješenja te odabir opcije za daljnju konstrukcijsku razradu.The scissor lift with a constant ratio of drive and manpower is intended for the purpose of lifting loads between two levels of logistics warehouse. The lifting platform of the scissor mechanism remains horizontal during lifting and lowering of the same, which allows safe transport of cargo between the two levels of the logistics warehouse. The mechanism is called scissor because there is a mechanism similar to the mechanism of manual scissors between the base and the lifting platform. One end of the scissors is attached to the base, while the other is attached to the lifting platform. The opposite ends of the scissors roll freely on the base and lifting platform. The paper begins with an introductory consideration of the types of lifting platforms for different purposes and conditions. Following with overview of the market and the elaboration of our own conceptual solutions, as well as the selection of options for further construction elaboration
