When it comes to special vehicles, our first instinct is often to distinguish them by their unique upper bodies. In the case ofautokraanas, we typically identify them by looking at the crane itself. Siiski, a crucial question arises: Is there a difference between the chassis of a autokraanaand the chassis of an ordinary truck? If so, what are these differences? And why is the chassis of aautokraanamore expensive than that of an ordinary truck? Let’s delve deeper into these questions to gain a better understanding.
Structural Differences in Beams
The beams of the chassis of aautokraanaare significantly different from those of an ordinary truck. Generally, the beams of a autokraanachassis are higher and thicker. This is crucial because when the crane is performing lifting operations, it exerts a considerable amount of torsional and tensile forces on the chassis. A stronger and sturdier beam is needed to withstand these forces and ensure the stability and safety of the vehicle.
The beams of an ordinary truck chassis are usually around 250 juurde 300 millimeters and are typically double-layer beams. In contrast, the beams of a special chassis for aautokraanameasure around 280 juurde 320 millimeters. The entire body of the chassis is generally two layers, but at the positions where the stress is relatively large at the front, middle, and rear, it is reinforced with three layers. Additionally, the spring steel plates on a autokraanachassis must also be thickened. When looking at the strengthened parts as a whole, it becomes evident that the beams of a special chassis for aautokraanaare basically three-layer thickened beams.
This enhanced structural design gives the vehicle a much stronger load-bearing capacity and tensile strength. With a more robust chassis, the autokraanacan better handle heavy loads during lifting operations and withstand the various forces exerted on it. Näiteks, when lifting a large and heavy object, the crane’s weight, combined with the weight of the load, places tremendous stress on the chassis. The thicker and higher beams ensure that the chassis can support this weight without buckling or deforming. This not only enhances the safety of the operation but also allows the crane to perform at its best, maximizing its lifting capacity and stability.
Installation and Distribution of Components
Another significant difference between the chassis of aautokraanaand an ordinary truck lies in the installation and distribution positions of various components. The chassis of a autokraanais designed with careful consideration for the specific requirements of the crane and its installation.
Näiteks, the air storage tank, battery, and exhaust pipe of aautokraanachassis are installed and distributed in a way that is reasonable and reserved when the chassis is produced. This is a crucial aspect as it helps to avoid improper operations such as “welding, cutting, and moving” on the chassis. These types of modifications can weaken the structural integrity of the chassis and pose a significant risk to the safety and performance of the vehicle.
In particular, for the chassis of a small three-axle truck, the width between the front wheels is reserved in advance. This allows for the non-destructive installation of the crane on the chassis. This is what we commonly refer to as a special chassis forautokraanas. By carefully planning the installation and distribution of components, the manufacturer ensures that the crane can be integrated seamlessly with the chassis without compromising its structural integrity or performance.
Näiteks, if the air storage tank or battery is installed in an inappropriate location on the chassis, it could interfere with the installation of the crane or affect the balance and stability of the vehicle. By reserving the correct positions for these components during the production of the chassis, the manufacturer ensures a smooth and safe installation process.
Special Components and Modifications
The chassis of autokraanas also come with several special components and modifications that set them apart from ordinary truck chassis. Allautokraanachassis use special gearboxes that are designed to handle the unique demands of operating a crane. These gearboxes are often built to withstand higher torque and provide better control during lifting operations.
Moreover, when a autokraanaleaves the factory, the original factory’s special power take-off device has been reserved in advance. This power take-off device is essential for operating the crane and transferring power from the engine to the crane’s hydraulic system. By having this device pre-installed, there is no need to modify the air and electrical circuits of the chassis. This not only simplifies the installation process but also ensures that the modifications are done correctly and safely.
For common rail models ofautokraanas, the electronic throttle converter is pre-installed. This allows for seamless integration with the engine and eliminates the need for any modifications to the engine. By pre-installing these components, the manufacturer ensures that theautokraanaoperates smoothly and efficiently, with minimal risk of breakdowns or malfunctions.
Theautokraanamodified in this way has better quality and a longer service life. The pre-installed components and careful design of the chassis ensure that the vehicle is optimized for crane operations and can withstand the rigors of heavy-duty use. Näiteks, without the proper modifications and components, theautokraanamay experience issues such as poor performance, frequent breakdowns, or even safety hazards. With the special gearboxes, power take-off devices, and electronic throttle converters, the crane can operate more reliably and efficiently.
Customization and Suitability
Because autokraanas are special vehicles, their chassis are also dedicated to a specific purpose. In essence, it can be said that the chassis of aautokraanais a customized chassis. This customization is designed to meet the unique requirements ofautokraanas and ensure their optimal performance and safety.
The special chassis of a autokraanais more suitable for the installation and use of autokraanas than the chassis of an ordinary truck. It is engineered to handle the specific loads, forces, and operations associated with crane work. The enhanced beams, proper component placement, and special modifications all contribute to making the chassis better suited for crane operations.
At the same time, this customized chassis can maximize the service life of the vehicle. By providing a stronger and more durable foundation for the crane, it reduces the risk of damage and wear, allowing theautokraanato operate for a longer period without requiring major repairs or replacements. Additionally, it enhances the performance of the vehicle by ensuring stability, control, and power transfer.
Price Justification
It is reasonable for the special chassis of a autokraanato be more expensive than the chassis of an ordinary truck. The extensive customization, enhanced structural design, and special components all contribute to the higher cost. The manufacturer invests significant time and resources in designing and producing a chassis that is specifically tailored forautokraanas.
The thicker beams, careful component placement, and pre-installed modifications require more materials and advanced manufacturing processes. Additionally, the research and development involved in creating a chassis that meets the unique requirements of autokraanas also add to the cost. Siiski, this higher price is justified by the superior performance, safety, and longevity that the special chassis provides.
In conclusion, the chassis of aautokraanais significantly different from that of an ordinary truck. The enhanced beams, proper component placement, and special modifications make it more suitable for the installation and use of autokraanas. While it may be more expensive, the benefits in terms of performance, safety, and service life make it a worthwhile investment for those in need of aautokraana. By understanding these differences, users can make more informed decisions when purchasing and operatingautokraanas.
