Craen wedi'i osod ar loritransporters are specialized transportation vehicles outfitted withcraen wedi'i osod ar loris to facilitate the self-loading and unloading of goods. Mae'r craen wedi'i osod ar lori, often referred to as a truck-mounted hoist, is not only extensively utilized in road logistics transportation but also finds application in numerous domains such as construction, railway, shipping, coedwigaeth, aerospace, grym, amddiffyn rhag tân, glanweithdra, mesur, wrecker rescue, national defense, a mwy, for the self-loading and transportation of goods. It stands as the preferred equipment for modern logistics transportation vehicles and operational vehicles.
According to the variations in the chassis, craen wedi'i osod ar loritransporters can be classified into three primary types: single vehicle type, semi-trailer type, and semi-trailer tractor type.
(1) Single vehicle type: Mae'r craen wedi'i osod ar loriis installed on a cargo truck (which could be a dump truck, lori grid warws, flatbed truck, etc.). This configuration offers several characteristics. Yn gyntaf, it provides flexibility in operation, allowing for easier maneuverability in various situations. Yn ail, it ensures a decent level of safety. Fodd bynnag, it has certain limitations, such as a relatively smaller load-carrying capacity, gallu codi, and operating range. This type is well-suited for scenarios where road conditions are suboptimal, the roads are narrow and winding, and the demands for lifting capacity and operating range are not overly high.
In areas with challenging terrains or where access is restricted, the single vehicle type’s compact size and maneuverability become valuable assets. Despite its lower capacity and range, it can effectively handle smaller-scale transportation and loading/unloading tasks in these specific circumstances.
(2) Semi-trailer type:Here, yr craen wedi'i osod ar loriis installed on a semi-trailer and requires towing by a semi-trailer tractor for movement. Yn nodweddiadol, the semi-trailer tractor is tasked with providing power to the hydraulic system of the semi-trailer. The quick connector of the hydraulic system tubing is located at the front of the semi-trailer, and the length of the tubing must have a certain allowance based on the turning radius of the semi-trailer tractor. This setup presents specific characteristics. One notable advantage is that the semi-trailer tractor can be repurposed for other tasks, achieving multi-purpose utilization of a single vehicle through drop and hook operations. The semi-trailer itself offers a significant load-carrying capacity. Yn ogystal, the crane’s lifting capacity and operating range can be substantial. Fodd bynnag, its drawback lies in reduced flexibility compared to other types. This configuration is more suitable for circumstances where road conditions are favorable and there are substantial requirements for load-carrying capacity, gallu codi, and operating range.
When dealing with large-scale transportation needs over long distances on well-maintained roads, the semi-trailer type’s high capacity and extended range make it a viable choice. Despite its less agile nature, it can efficiently handle heavy loads and extensive operations in such contexts.
(3) Semi-trailer tractor type:In this type, yr craen wedi'i osod ar loriis installed on the tractor. Constrained by the rear towed vehicle (lled-ôl-gerbyd), a foldingcraen wedi'i osod ar loriis commonly assembled. It exhibits distinct characteristics, including a large lifting capacity, high flexibility, the ability for independent use, and relatively lower requirements for the towed vehicle. This makes it suitable for short-distance transportation of multiple goods and associated loading and unloading operations.
The semi-trailer tractor type is well-suited for scenarios where frequent stops and starts are necessary, and the ability to quickly adapt to different loading and unloading points is crucial. Its flexibility and independent operation capabilities make it efficient for local and regional transportation tasks.
I gloi, the classification ofcraen wedi'i osod ar loritransporters based on chassis differences provides a range of options to meet the diverse requirements of various transportation and operational scenarios. The choice among these types depends on factors such as road conditions, load demands, lifting requirements, operating range, and the level of flexibility needed for specific applications. Understanding these distinctions enables the selection of the most appropriate type to ensure efficient and effective transportation and loading/unloading processes.
