Lifting and rigging equipment includes a wide range of mechanical and metal components designed for safely lifting, moving, and securing loads in industrial environments. These components include wire rope slings, chain slings, polyester webbing slings, shackles, turnbuckles, crane hooks, master links, hook blocks, swivels, clamps, and various plate or beam lifting grips. Each item is selected based on its rated capacity, safety factor, load characteristics, ambient conditions, and operational requirements, and is manufactured and tested according to international standards such as EN 13414, EN 818, and ASME B30. Proper selection and use of lifting accessories significantly reduce stress on lifting structures, enhance operational safety, and extend the service life of the equipment, making load weight, lifting angles, and connection type to the crane hook critical factors in choosing the correct rigging tools.
Wire ropes used in lifting operations are manufactured in various constructions, each designed to deliver specific levels of flexibility, abrasion resistance, and rotational stability. Common structures include 6x19, 6x36, 8x19, and 18x7, with each configuration optimized for different mechanical behaviors under load. Non-rotating wire ropes are utilized for high-lift applications to prevent load spinning, while IWRC Independent Wire Rope Core ropes offer higher tensile strength and longer service life in heavy industrial environments. Materials typically include high-carbon steel, galvanized steel, and stainless steel, and the selection of the appropriate wire rope depends on factors such as working load, lifting speed, environmental conditions, and required fatigue resistance.
Lifting chains and their associated fittings form another essential part of load-handling systems and are produced in various grades such as 80, 100, and 120. Grade 80 chains are commonly used for general lifting, Grade 100 for heavy-duty operations, and Grade 120 for ultra-heavy and shock-sensitive applications. Rigging accessories include shackles, turnbuckles, master links, safety hooks, eye hooks, swivels, plate clamps, beam clamps, and quick connectors. Each component is manufactured according to standards such as ASME B30 and EN 818 to ensure safe force transmission, proper load distribution, and protection against sudden failure under dynamic loading conditions.
Overhead cranes are the primary load-handling systems in industrial facilities and are available in several types including Single Girder, Double Girder, Monorail, Gantry, and Semi-Gantry cranes. These cranes are typically equipped with electric wire rope hoists or electric chain hoists, trolley systems, cable reels, and variable frequency drives VFD for precise speed control. The choice of crane depends on load capacity, building span, lifting height, duty class FEM/ISO, and operational requirements. When correctly paired with appropriate wire ropes and certified lifting accessories, overhead crane systems significantly enhance lifting efficiency, reduce equipment wear, and improve overall workplace safety.
