1. There are specific requirements for the steel plate specifications produced by cranes, ensuring that cranes can be safely used within a defined thickness range. Operators must confirm that the crane's capacity matches the weight and dimensions of the steel plates being lifted.
2. Special attention should be given to the operating conditions of cranes when lifting workpieces or in particular environments. For special lifting tasks, it is essential to use cranes designed for such purposes, with appropriate markings and clear instructions on their intended use.
3. Ordinary workpiece lifting can typically be performed by certified crane operators, but any operation involving suspending or securing the workpiece must be carried out by a qualified individual trained in suspension and loading procedures.
4. It is strictly prohibited to strike or collide with hanging objects or spreaders, as this can cause damage, instability, or even failure of the lifting equipment.
5. Overloading cranes is not allowed. All lifting operations must be conducted within the crane’s rated capacity, ensuring that the load remains within the safe working limit.
6. During the crane operation process, sudden movements or abrupt stops should be avoided to prevent uncontrolled swinging or potential accidents.
7. Operators must not approach the area where workpieces are being lifted or where they are suspended and transported. Maintaining a safe distance is crucial for personal safety.
8. Certain illegal operations, such as stage lifting, heavy lifting, horizontal grabbing, co-hanging, or leaning objects, are strictly prohibited. These actions increase the risk of accidents and should never be performed.
9. Using the crane beyond its designated workload is strictly forbidden. This includes exceeding the maximum lifting capacity or using the crane for unintended purposes.
10. To enhance safety, it is recommended to use two or more spreader clamps when lifting heavy loads, which helps distribute the weight evenly and reduces the risk of overloading.
11. Before each use, lifting steel clamps must be carefully inspected for any signs of wear, damage, or malfunction. Check for bite conditions, gasket issues, tooth clogging, and ensure all components are functioning properly. Regular maintenance and inspection are essential to prevent failures during operation.
