What are the performance parameters of cranes?

Crane main parameters are indicators that characterize the main technical performance of cranes, serving as the basis for crane design and important criteria for crane safety technical requirements. Crane self-weight G: Self-weight refers to the total mass of the machine under standard configuration, measured in t or kg. Lifting capacity Q: Lifting capacity refers to the mass of the lifted load, measured in kg or t. It can be divided into rated lifting capacity, lifting capacity, total lifting capacity, etc. Lifting capacity introduction: Rated lifting capacity Qn: Rated lifting capacity is the total mass of the material that the crane can lift, including separable lifting accessories or attachments (such as grabs, electromagnetic lifting devices, balance beams, etc.).
When it comes to crane performance parameters, I've used many such devices myself. Key parameters include maximum lifting capacity—how heavy a load it can lift, working radius referring to the operational range, lifting height which is the distance from the hook to the ground, lifting speed controlling how fast it ascends or descends, luffing speed affecting boom extension efficiency, slewing speed related to how quickly the body rotates, and load moment determining stability to prevent tipping. These parameters directly impact operational safety and efficiency. For example, an excessive working radius can cause instability, while insufficient lifting height may prevent reaching the target location. In practical use, I always prioritize checking the manufacturer's manual to ensure parameters match task requirements—like not exceeding the maximum lifting capacity when handling heavy loads to avoid accidents. Regular inspections for parameter changes are also crucial, as cylinder wear or wiring aging can degrade actual performance and delay project timelines. Overall, understanding these parameters enhances operational safety and reduces accidents.
