Description

Technical Field

[0001] The utility model relates to the technical field of hydraulic telescopic booms, in particular to a hydraulic telescopic boom which is convenient for length adjustment. Background Art

[0002] Hydraulic telescopic boom is a kind of equipment widely used in engineering and construction fields. It can be extended and retracted through the hydraulic system. Its main advantages include large load capacity, high operation flexibility, large operation range, time saving and high efficiency. Hydraulic telescopic boom can adapt to the operation requirements of different heights and distances, improve work efficiency and safety, and provide reliable solutions for various lifting and handling tasks. In the field of engineering and construction, the application of hydraulic telescopic boom equipment has been widely recognized and adopted.

[0003] In the process of realizing the utility model, the inventor found that the prior art has the following problems: 1. Most of the existing hydraulic booms use hydraulic telescopic booms, which can only lift objects directly below them horizontally, and such hydraulic telescopic booms are difficult to rotate left and right, making it difficult to lift objects on both sides of the boom; 2. Most of the existing hydraulic booms use hydraulic cylinder pushing devices to realize the function of lifting and retracting the boom, thereby realizing the adjustment of the boom height. However, the telescopic range of the hydraulic cylinder is limited, which depends on the design of the hydraulic system and the size of the hydraulic cylinder. This means that the hydraulic telescopic boom has a certain height range limitation in terms of height adjustment, and may not meet the needs of some specific scenarios. Utility Model Content
