Purpose: it is used in handling hot-rolled, cold-rolled horizontal coils, or unloading operation. Characteristic: 1.The operation efficiency is high, and the loading uploading rate of mechanical horizontal coil clamp can be increased one time higher, being compared with electric horizontal coil clamp. 2. No damage steel coil. 3. Operation is convenient, which can be implemented by lifting hook only, 4. Electric source is not needed. It is applicable in high and low temperature environments. 5. When operated, it should be opened to the maximal jaw opening, so it needs large space.
