Introduction
The C-type steel coil lifting tongs consists of C-shaped main beam, upper lifting lug, lower fork arm (insertion arm), clamping mechanism, guide wheels and protective pads. The main beam is welded from high-strength low-alloy steel plates into a box-type C-shaped structure, annealed to eliminate internal stress, with good rigidity, strong load capacity and small deformation. During operation, the crane hook lifts the sling through the upper lifting lug, horizontally inserts the lower fork arm into the steel coil inner hole; after continued lifting, the C-type sling uses self-weight and lever principle to make the upper beam press the steel coil outer wall and the lower fork arm support the steel coil inner wall, forming reliable clamping to achieve steel coil lifting; automatically releases after lowering, convenient for loading and unloading. Horizontal coil type is used for lifting steel coils placed horizontally (axis horizontal), the most commonly used type in steel mills; vertical coil type is used for lifting steel coils placed vertically (axis vertical); electric flipping type can achieve 90° horizontal-vertical flipping of steel coils. The lower fork arm contact surface is equipped with nylon or polyurethane pads to prevent scratching the steel coil surface; some models are equipped with guide wheels for easy alignment with the steel coil inner hole. The C-type steel coil lifting tongs is widely used in steel coil transfer in hot rolling, cold rolling, galvanizing and color coating production lines of steel mills, as well as steel coil loading/unloading and stacking in steel coil warehouses and logistics centers, serving as a dedicated and efficient sling for steel mill coil lifting.
Application
Our Advantage
The C-shaped structure is specially designed for lifting through the steel coil inner hole; the lower fork arm can be directly inserted into the steel coil inner hole, using the C-shaped opening to support the steel coil without wire rope binding, especially suitable for mass steel coil transfer in steel mills, lifting efficiency far higher than general-purpose slings.
Uses the C-type sling self-weight and lever principle to achieve automatic clamping; the clamping force increases with the load during lifting, forming reliable self-locking, will not loosen due to vibration and sway during lifting; safety factor ≥4 times, tested via 1.25× rated load static test, ensuring safe heavy-load steel coil lifting.
Only need to align the lower fork arm with the steel coil inner hole and insert, lifting automatically clamps, lowering automatically releases, no manual binding, untying and adjustment needed; horizontal coil type can be lifted with a single sling, vertical coil type can be used with C-hook or electric flipping, short loading/unloading time, steel coil transfer efficiency over 3 times higher than wire rope binding.
The lower fork arm and upper beam contact surfaces are equipped with nylon or polyurethane protective pads, both increasing friction to prevent slipping and avoiding direct metal contact scratching the steel coil surface; clamping force is evenly distributed without causing local deformation of the steel coil, especially suitable for lifting cold-rolled coils, galvanized coils and color-coated coils with high surface quality requirements.
Main beam is welded from high-strength low-alloy steel plates into a box-type structure, annealed after welding to eliminate internal stress, with good rigidity, strong load capacity and small deformation; lower fork arm contact surface is high-frequency quenched, with high hardness and wear resistance; normal service life over 8 years, low maintenance cost, suitable for 24-hour continuous operation environment in steel mills.
