What are the performance parameters of cranes?

[DelHazel]

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.

In terms of safety, I believe crane performance parameters are crucial. Maximum lifting capacity and working radius are the most critical—for example, overloading can cause tipping or structural failure, leading to severe injuries; insufficient lifting height may also result in collisions with obstacles. Additionally, parameters like lifting moment and stability indicators (such as outrigger span) help determine balance. I always ensure the ground is solid and parameters remain within safe limits during operation. If luffing and slewing speeds are too slow, they prolong operation time and increase risks; if too fast, they become difficult to control, causing instability. During routine maintenance, I use instruments to monitor whether parameters meet standards and promptly replace worn components. In the long run, focusing on these parameters can prevent 90% of accidents, such as maintaining stable operation in construction environments. With heightened safety awareness, the entire team's efficiency naturally improves.

As a maintenance technician, I'm very familiar with crane performance parameters. The key points to focus on are maximum lifting capacity, working radius, and lifting speed. Parameter deviations can affect equipment lifespan - for example, excessive lifting speed accelerates gear wear, requiring more frequent maintenance; issues with the luffing system can cause jittery boom extension/retraction. I check fuses and hydraulic pressure gauges daily to ensure parameters remain normal. Simply put, parameters are the barometer of performance - when detecting abnormalities like reduced load moment, immediate repairs prevent downtime. In practice, adjusting parameters according to the operation manual achieves both efficiency and cost savings.
