What are the specifications of cranes?

[McElliana]

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.

From a safety perspective, crane specifications are a matter of life and death. I've handled several accident investigations where the root causes all lay in the details. The lifting capacity must strictly match the task—overloading is absolutely forbidden. Boom length has limitations; excessive length can lead to dangerous swaying in strong winds. The maximum height and radius within the working range must be clearly defined, and the on-site space should be planned in advance. Stability characteristics, such as outrigger width and chassis weight, must accommodate slopes or soft ground conditions. Engine power cannot be overlooked, as insufficient power under heavy loads can easily lead to failures. The pressure settings of the hydraulic system act as a safety net—any leakage requires an immediate shutdown. I've also seen cases where operation manuals neglected lifting limits, leading to accidents. Overall, these specifications are not just theoretical but form the foundation of on-site operations. Adhering to regular maintenance and training can prevent tragedies. As someone deeply committed to safety, I believe installing overload alarms and automatic braking systems is also essential—it makes daily operations more reassuring.

As an automotive mechanical enthusiast, I find crane specifications quite fascinating. Although I don't operate them directly, understanding them broadens my horizons. The lifting capacity indicates capability, typically measured in units like 5 or 10 tons. The boom length determines the reach, ranging from a dozen to thirty meters, offering flexibility for various scenarios. Working height and rotation angle affect spatial control, with 360-degree rotation being particularly useful for loading and unloading. Dimensions including vehicle length and weight influence road transport convenience. Power sources like diesel engine output determine work efficiency; some modern cranes even use hydraulic systems to reduce noise and pollution. These specifications combined reflect engineering wisdom. I often search online for materials or watch videos to learn - why choose different tonnages? Is it for economic reasons or task requirements? Such little knowledge makes daily life more interesting.
