What are the specifications of cranes?

The specifications of cranes are as follows: Introduction: Crane specifications are generally classified by tonnage. Cranes below 15t are considered small-tonnage cranes, those between 16-45t are medium-tonnage cranes, and those with a rated lifting capacity above 26t are large-tonnage cranes. Small-tonnage cranes mainly include 8-ton, 16-ton, 25-ton, 50-ton, 70-ton, and 100-ton models. Large-tonnage all-terrain cranes include 160-ton, 220-ton, 300-ton, 400-ton, 500-ton, and 800-ton models. Additional information: Operators should be aware that overloading or lifting objects with unclear weight is prohibited; lifting is also prohibited when the command signal is unclear.
When operating a crane, I always check the core specifications first, as they directly impact work efficiency and safety. The maximum lifting capacity is crucial, measured in tons (e.g., common 5-ton or 10-ton models), determining the weight of objects that can be lifted—but never exceed the limit to avoid accidents. Boom length is equally important, ranging from a dozen meters for short booms to over thirty meters for long ones, enabling the crane to reach farther or higher points; I've relied on long booms to solve major challenges in confined construction sites. The working range includes lifting height and rotation radius, which must be evaluated in combination with terrain, especially on uneven ground. Outrigger designs enhance stability and prevent tipping. Regarding dimensions, the vehicle's self-weight affects mobility—large cranes may require transport, while compact models offer greater flexibility. Power output comes from diesel engines or hydraulic systems, controlling speed and work intensity, with regular leak inspections required. Combining these specifications with manuals and safety training significantly improves on-site performance. Having personally experienced delays caused by neglecting them, I recommend beginners familiarize themselves with these details through practice to minimize risks and maintain equipment longevity.
