Have you ever wondered? Special vehicles typically employ specialized chassis. For instance, mixer trucks must utilize the specific chassis designed for mixer trucks, wrecker trucks need the dedicated chassis for wrecker trucks, and truck-mounted cranes have their own specialized chassis. On the surface, there might not be a conspicuous distinction, yet the chassis of special vehicles is typically more costly than that of ordinary trucks. But why is this the case? Could it be that the salespeople are providing misleading information? Certainly not. Today, the editor will use the truck-mounted crane as an example to elaborate on the disparities between the special chassis of the truck-mounted crane and the ordinary truck chassis.
The girder of the special chassis for the truck-mounted crane is taller and thicker compared to that of the ordinary truck chassis. When the crane is in the process of lifting, it possesses enhanced anti-torque and anti-tensile capabilities. The girder of an ordinary truck chassis typically ranges from 13 to 180mm. In contrast, the girder of the special chassis for the truck-mounted crane measures between 200 to 300mm. At the positions that endure greater stress at the front, middle, and rear, it consists of three layers. When considering the reinforced areas as a whole, the girder of the special chassis for the truck-mounted crane is fundamentally stronger in terms of load-bearing and tensile resistance, and is capable of better facilitating the performance of the truck-mounted crane.
Let’s delve deeper into this aspect. The increased height and thickness of the girder play a crucial role in distributing and absorbing the forces exerted during the lifting operation. When the crane lifts heavy loads, significant torques and tensile forces are generated. A stronger and thicker girder helps to evenly distribute these forces throughout the structure, reducing the risk of local stress concentrations and potential failures. This not only enhances the safety of the operation but also prolongs the lifespan of the chassis.
The installation and distribution positions of the air storage tank, battery, and exhaust pipe on the special chassis of the truck-mounted crane are strategically designed to be more conducive to the installation of the crane. This eliminates the need for improper operations such as welding and cutting on the chassis, allowing for non-destructive installation of the crane onto the chassis.
This aspect is of paramount importance as it ensures the integrity and structural stability of the chassis. By having pre-defined and optimized locations for these components, the installation process of the crane becomes smoother and more efficient. It also reduces the potential for damage or weakening of the chassis during the modification and installation procedures.
The special chassis of the truck-mounted crane is equipped with a power take-off device, and the suspension system of the vehicle is reinforced. This results in a more rational axle load distribution for the entire vehicle of the truck-mounted crane during driving.
The power take-off device enables the crane to draw power from the vehicle’s engine, ensuring efficient and reliable operation. The strengthened suspension system helps to handle the additional weight and dynamic forces exerted during crane operations and driving. A well-distributed axle load ensures improved handling, stability, and tire wear, contributing to a safer and more reliable driving experience.
The special chassis of the truck-mounted crane adopts a specialized gearbox and is pre-fitted with a dedicated power take-off device. There is no requirement to modify the air and electrical circuits of the chassis. Even for common rail models, electronic throttle converters are pre-installed.
The specialized gearbox is engineered to handle the specific torque and speed requirements of the crane operations. The pre-installed power take-off device and other components ensure seamless integration and compatibility, reducing the need for aftermarket modifications and potential reliability issues. This pre-configuration simplifies the installation process and enhances the overall performance and reliability of the vehicle.
The abovementioned characteristics are specific to the special chassis of the truck-mounted crane. The same principle applies to other special vehiclechassis, all of which are tailored for specific vehicle types. Each type of special vehicle chassis boasts its unique attributes and is meticulously designed by professionals. These professional designs can effectively guarantee their working efficiency and usage safety. You can make your purchase with complete confidence.
For example, the special chassis for fire engines is designed to accommodate the heavy equipment and water tanks while maintaining stability and maneuverability in emergency situations. Similarly, the chassis for ambulances is configured to provide a smooth ride and have easy access points for medical equipment and stretcher loading.
In conclusion, the use of special chassis for special vehicles is not only a matter of enhanced performance and safety but also a reflection of the specialized and demanding requirements of various applications. By investing in these purpose-built chassis, operators can ensure that their vehicles are optimally equipped to perform their specific tasks with reliability and efficiency.
