Автокранs are categorized based on the number of axles, such as two-axle, three-axle, four-axle, and so forth. For the same number of axles, the wheelbase can vary, either being larger or smaller. И така, what exactly are the implications of the wheelbase on the performance ofавтокранs? Specialists in автокранs inform us that the wheelbase of aавтокранis intricately linked to the performance of the entire vehicle, as the wheelbase determines the position of the center of gravity of the автокран. Следователно, if the wheelbase of theавтокранundergoes a change, the entire vehicle configuration must be reorganized, particularly the dimensions of the transmission system and the body. The parameters of the springs and shock absorbers within the suspension system need to be recalibrated, the size of the trapezoidal tie rods in the steering system needs adjustment, and simultaneously, a change in the wheelbase will also cause alterations in the distribution of axle loads on the front and rear axles.
The most immediate impact of the wheelbase on theавтокранis the length of the vehicle body, which further influences the interior space. например, the wheelbase of a blue-plateавтокранis typically around 3300mm. Due to this relatively shorter wheelbase, the space in its rear seat is relatively confined. За разлика от тях, the wheelbase of a yellow-plateавтокранis generally above 4000mm. With this longer wheelbase, the space in its rear seat is significantly more generous. Следователно, the wheelbase plays a decisive role in determining the length, available space, and comfort level within the vehicle body.
The wheelbase also has a considerable bearing on the passability and stability of theавтокран. А автокранwith a short wheelbase benefits from a shorter overall length, lighter mass, smaller turning radius, and passage radius. This enables it to navigate through relatively narrow sections with greater ease. Въпреки това, the drawback of an overly short wheelbase is that it compromises the vehicle’s maneuverability and stability. От друга страна, а автокранwith a large wheelbase has a longer overall length and greater mass. Its center of gravity is located farther from the support points, resulting in relatively stable driving and a reduced likelihood of rollover incidents. Nevertheless, such a configuration comes with a larger turning radius, a larger reversing blind area at the rear, увеличаване на риска от злополуки, and making it less suitable for narrow road conditions.
The size of the wheelbase also has an impact on the installation of the crane on theавтокран, which is particularly evident in double-steering axleавтокранs. например, in the case of small three-axle and front-four-rear-eightавтокранs, when installing the crane on these two types of vehicles, the outrigger component of the crane must be positioned between the two steering axles. If the wheelbase between the steering axles is excessively short, it becomes impossible to lower the outriggers, especially for large-tonnage cranes, which are typically rear-mounted.
The wheelbase is a critical factor that affects multiple aspects of theавтокран‘s performance. It influences the vehicle’s handling, stability, interior space, and the installation of the crane itself. A well-chosen wheelbase can optimize theавтокран‘s capabilities to suit specific operational requirements and working conditions. When purchasing a автокран, potential buyers must carefully consider the wheelbase in relation to the intended use of the vehicle. Ако автокранis primarily intended for operations in confined spaces or areas with narrow roads, a shorter wheelbase might be more appropriate to ensure maneuverability. Въпреки това, if stability and a larger working platform are priorities, a longer wheelbase could be the better choice.
The decision regarding the wheelbase should also take into account factors such as the weight and size of the loads to be lifted, the frequency and nature of the lifting operations, and the terrain and road conditions in which the vehicle will be operating. A comprehensive assessment of these factors can lead to a more informed choice of wheelbase, thereby maximizing the efficiency and safety of theавтокранin its intended application.
В заключение, the wheelbase is not just a simple specification but a key determinant of the overall performance and functionality of theавтокран. Paying close attention to this aspect during the purchasing process is essential to ensure that the vehicle meets the operational needs and expectations of the user.
