No matter what type of Isuzu truck-mounted crane it is, it consists of a frame (the connecting frame between the main frame of the car and the truck-mounted crane), boom assembly, slewing mechanism, lifting mechanism, hydraulic outriggers, hydraulic cylinders, and control systems. It consists of main components such as (wired control or wireless control) and spreaders or grabbers for various purposes. The following is an introduction to some of its main parts: 1.Hydraulic legs:In modern hydraulic lifting, the outrigger type is retractable, and its expansion and contraction is hydraulically driven. Isuzu truck-mounted crane adopts H-type outriggers, which have a large extension distance. Each leg has at least one vertical support hydraulic cylinder. Some of them are driven by hydraulic pressure in the horizontal direction, and some are operated by humans to achieve horizontal movement. The legs are ugly when extended. In order to ensure sufficient extension distance, the left and right outriggers are spaced apart from each other. H-type outriggers have good adaptability to the ground and are easy to level. They are widely used on medium and large cranes. However, the height of H-type outriggers affects the working space. At the same time, the outriggers must be firmly connected to the beams to ensure the stability of the outrigger structural system. 2. Boom assembly: The boom of Isuzu truck-mounted crane adopts a box-shaped arm, whose main function is to support the load and change the working radius. The folding boom is connected together through a rotating shaft and a folding hydraulic cylinder. The boom usually consists of a fixed arm and several telescopic arms. A straight-arm crane usually consists of a fixed arm and several telescopic arms. The extension and retraction of only one or two sections of the telescopic arm are driven by a hydraulic cylinder, while the extension and retraction of a multi-section telescopic arm are driven by a hydraulic cylinder and a wire rope installed inside the boom. 3. Hoisting mechanism: The main mechanism of the hoisting mechanism type hoisting machinery is used to realize the lifting movement of heavy objects. It usually consists of a prime mover, reducer, drum, brake, clutch, wire rope pulley group and hook. The lifting mechanism of the truck-mounted crane adopts hydraulic transmission. 4. Slewing mechanism: The Isuzu truck-mounted crane sends the lifted objects to any space within the designated working range. In addition to relying on the lifting mechanism to realize the vertical displacement of the heavy objects, the slewing motion method achieves horizontal displacement. Although this form of motion is The horizontal movement range is limited, but the required power is small, the structure is simple, and it is widely used. Generally, the full-rotation type is used, which can rotate freely in the left and right directions. The full-turn slewing mechanism of the truck-mounted crane consists of three part...
