The full name oftruck-mounted crane is truck with crane, which indeed holds several advantages such as excellent mobility, rapid transferability, and a wide range of applications. It ingeniously integrates lifting and transportation functions. The crane can be equipped with a variety of auxiliary tools like grabs, drilling tools, and hanging baskets, finding extensive use in places such as engineering construction, tree planting in gardens, and power maintenance. The market prospect for truck-mounted cranes is truly broad. According to the configuration of the boom, truck-mounted cranes can be divided into two main types: straight boom and folding boom. In terms of tonnage, they can be classified into numerous categories including 1 ton, 2 tons, 3.2 tons, 4 tons, 5 tons, 6.3 tons, 8 tons, 10 tons, 12 tons, 14 tons, 16 tons, 18 tons, 20 tons, 25 tons, 30 tons, and more. Renowned brands in the market include Sany, XCMG, Changxing, Shimei, Hongchang Tianma, and many others. There are also a diverse range of truck-mounted crane chassis available, encompassing two axles, three axles, four axles, and so on. Prominent chassis brands consist of Dongfeng, Shaanxi Auto, Dayun, Sinotruk, FAW Jiefang, Foton, and more. So, what exactly is the relationship between the tonnage of a truck-mounted crane and the vehicle’s axles and wheelbase?
Chassis of different sizes need to be carefully matched with cranes of appropriate tonnages. Installing a small-tonnage crane on a large-wheelbase chassis can be considered overkill. On the other hand, mounting a large-tonnage crane on a small, short-wheelbase chassis can pose significant challenges as the chassis frame may not be able to bear the weight of the crane. Only by pairing a suitable chassis with a suitable crane can one ensure both the quality of the vehicle and its work efficiency.
Let’s start with the blue license plate (drive form: 4×2). In the wheelbase range of 3300 – 3600, the blue license plate chassis can be equipped with cranes of 2 tons, 3.2 tons, 4 tons, and 5 tons. This specific combination is well-suited for applications where a relatively lighter load capacity is required and maneuverability in confined spaces is essential. For example, in urban construction sites with narrow streets and limited access, a truck-mounted crane with a blue license plate and a smaller tonnage crane can easily navigate and perform tasks such as lifting and transporting light materials or equipment.
The small yellow license plate single axle (drive form: 4×2) with a wheelbase range of 3900 – 4500 offers more flexibility in terms of crane capacity. It can be equipped with 4 tons, 5 tons, and 6.3 tons of cranes. This configuration is suitable for slightly larger-scale operations where a bit more lifting power is needed but still within a reasonable range. For instance, in landscaping projects or small-scale industrial settings, these truck-mounted cranes can handle tasks like lifting trees or medium-sized machinery components.
The yellow license plate single axle (drive form: 4×2) in the wheelbase range of 4700 – 5100 can be fitted with 5 tons, 6.3 tons, and 8 tons of cranes. This combination is designed for more demanding applications where a stronger lifting capacity is required. It can be utilized in construction projects that involve lifting heavier materials or equipment. The longer wheelbase provides better stability and balance, enabling the crane to handle heavier loads safely.
Moving on to the front four and rear four (drive form 6X2), also known as the regular small three-axle configuration. This setup can be equipped with 8 tons, 10 tons, and 12 tons of cranes. The additional axles provide increased load-bearing capacity and stability, making it suitable for medium to large-scale construction projects. For example, in building high-rise structures or large infrastructure projects, these truck-mounted cranes can play a crucial role in lifting heavy steel beams or prefabricated components.
The rear eight-wheel chassis (drive form 6X4), or the regular rear double-axle configuration, can handle even heavier loads. It can be equipped with 10 tons, 12 tons, and 14 tons of cranes. This is ideal for applications where extreme load-bearing capacity and stability are essential. In large construction sites or industrial settings with heavy-duty lifting requirements, these truck-mounted cranes can handle massive loads with ease.
Finally, the front four and rear eight chassis (drive form 8X4) is the most powerful option in terms of load capacity. It can be equipped with 12 tons, 14 tons, 16 tons, 18 tons, and 20 tons of cranes. This configuration is suitable for the heaviest lifting tasks, such as in large-scale construction projects, oil and gas fields, or heavy industry. The multiple axles and longer wheelbase ensure maximum stability and load-bearing capacity, allowing the crane to handle extremely heavy loads safely and efficiently.
The above represents the best matches between the chassis and the crane. When purchasing a truck-mounted crane, it is highly advisable to be well-informed about this knowledge. Understanding the relationship between the tonnage of the crane and the characteristics of the chassis is crucial for making an informed decision. It ensures that the purchased vehicle is not only capable of meeting the specific lifting requirements of the intended applications but also operates safely and efficiently. Additionally, considering factors such as the working environment, terrain, and frequency of use can further help in choosing the most suitable truck-mounted crane configuration.
In conclusion, the proper matching of the tonnage of a truck-mounted crane with the vehicle’s axles and wheelbase is essential for optimizing its performance and ensuring its reliability. By carefully considering these factors and consulting with experts or experienced users, one can make a wise investment in a truck-mounted crane that meets the specific needs of their business or project.
