Výrobcovia zdvíhacích reťazí

Zdvíhacie reťaze are typically made from high-quality alloy steel, which provides excellent strength and durability. They consist of a series of interconnected links that form a continuous chain. Zdvíhacie reťaze are available in different sizes, grades, and configurations to match specific load requirements. They may feature different types of end fittings, such as hooks, shackles, or rings, for convenient connection to lifting devices. Zdvíhacie reťaze are designed to meet industry standards and regulations for load capacity, safety, and performance.

Zdvíhacie reťaze find application in a wide range of industries and sectors that involve material handling and lifting operations. They are commonly used in construction sites for lifting heavy equipment, building materials, and structural components. Zdvíhacie reťaze are valuable in manufacturing facilities for hoisting machinery, engines, or heavy parts. They are also employed in the transportation and logistics industry for cargo handling and securing loads on trucks, cranes, or ships. Additionally, lifting chains are used in the mining, oil and gas, and marine sectors for various lifting and rigging tasks.

Správne používanie zdvíhacích reťazí je rozhodujúce pre zaistenie bezpečných zdvíhacích operácií a zabránenie nehodám alebo poruchám zariadenia. Je dôležité vybrať vhodnú zdvíhaciu reťaz na základe požiadaviek na zaťaženie, limitov pracovného zaťaženia a priemyselných noriem. Pravidelná kontrola a údržba zdvíhacích reťazí je potrebná na zistenie akýchkoľvek známok opotrebovania, poškodenia alebo deformácie, ktoré môžu ovplyvniť ich pevnosť. Správne školenie a dodržiavanie bezpečnostných pokynov je nevyhnutné pre operátorov a riggerov pracujúcich so zdvíhacími reťazami, aby sa minimalizovali riziká a zabezpečil optimálny výkon.

The safety measure was identifying which types of chain are appropriate and strong enough for overhead lifting. Anytime we move or lift a load it is dangerous. Moving a load along the ground has the advantage that the ground is supporting the load. We have to overcome the coefficient of friction to move the load. The chain’s working load limit does not have to match the weight of the load. It needs to be able to handle the tension applied, which is based on the surface that it is being moved over plus some fraction of the weight of the load. This can be calculated using formulas.

If we lift that same load off the ground, we now have to overcome gravity. The chain’s working load limit will have to be of sufficient strength to support the weight of the load plus any additional forces imposed by angles and hitch type(s) used.
