ဟိ ထရပ်ကားတပ်ဆင်ထားသောကရိန်း, often abbreviated as truck with crane, has seen an ever-increasing prevalence in various applications due to its unique ability to both lift and transport goods. Nowadays, many truck-mounted cranes are equipped with hydraulic outriggers, which are further divided into front outriggers and rear outriggers. While the main function of the front outrigger is well-known for dispersing the gravity of the entire vehicle and enhancing the carrying capacity, the function of the rear hydraulic outrigger remains somewhat ambiguous to many. Some people even mistakenly believe that the rear hydraulic outrigger is redundant. သို့သော်, this is far from the truth. ဒီနေ့, let’s delve deeper into understanding the usage and significance of the rear hydraulic outrigger of aထရပ်ကားတပ်ဆင်ထားသောကရိန်း.
Let’s begin by discussing the installation position of the hydraulic rear outrigger. Typically, the rear outrigger is installed on the chassis of the rear wheels of the rear axle of theထရပ်ကားတပ်ဆင်ထားသောကရိန်း. လောလောဆယ်, the rear outrigger is mostly in an H-shaped configuration. The most crucial function of the rear outrigger is to provide essential rear support for the entire vehicle. During the operation of the crane, a portion of the load can be transferred to the outrigger. This transfer of load is of utmost importance as it ensures the bottom support strength of the vehicle. ဒီလိုလုပ်ခြင်းအားဖြင့်, it effectively prevents potential dangers that could arise from excessive pressure on the tires.
Imagine a scenario where aထရပ်ကားတပ်ဆင်ထားသောကရိန်းis lifting a heavy load. Without proper rear support, the weight of the load could cause the rear tires to bear an excessive burden, potentially leading to instability and even tire blowouts. The rear outrigger acts as a stabilizer, distributing the load and ensuring that the vehicle remains firmly planted on the ground. This not only enhances safety but also allows for more precise and controlled lifting operations.
ကဲ, let’s explore the different types of rear hydraulic outriggers available in the market. At present, the more common rear outriggers include the fixed type, single-chamber hydraulic type, and double-chamber hydraulic type. Generally, cranes from big brands are often equipped with original rear outriggers. These original products are renowned for their superior quality and excellent performance. It is also important to note that the rear outrigger should be appropriately matched with the tonnage of the crane. Different types of outriggers are suitable for various applications and working conditions.
The fixed rear outrigger can be lifted and lowered vertically. This simple yet effective design provides crucial support and assistance during lifting operations. It is particularly useful in situations where a stable base is required, and the vertical movement allows for easy adjustment to different ground levels. ဥပမာအားဖြင့်, when working on a relatively flat surface with minor variations in elevation, the fixed rear outrigger can be quickly deployed to ensure stability.
The single-chamber hydraulic outrigger offers additional functionality by being able to extend left and right. This feature enables it to extend beyond the size of the cargo box, providing a wider base of support. With both left-right extension and vertical extension capabilities, it offers enhanced support compared to the fixed type. ဥပမာအားဖြင့်, in a construction site with limited space, the single-chamber hydraulic outrigger can be extended to reach a stable position on adjacent surfaces, ensuring the crane’s stability even when working close to obstacles.
The double-chamber hydraulic type takes support to an even higher level. It includes both left-right extension and vertical lifting functions, and its extension width is larger than that of the single-chamber type. This results in stronger support, making it ideal for more demanding lifting operations. ဥပမာအားဖြင့်, when lifting extremely heavy loads or working in challenging terrains where stability is of paramount importance, the double-chamber hydraulic outrigger can provide the necessary support to ensure safe and successful operations.
The places where the rear outrigger is generally applied are diverse and depend on specific working conditions. Uneven or relatively soft ground at the lifting site is one such scenario. In these situations, the outrigger can help distribute the load more evenly and prevent the vehicle from sinking or tipping over. When maximum working radius slewing operation is required during the lifting process, the rear outrigger provides additional stability to counteract the increased forces exerted on the vehicle. If the lifted item is close to the maximum lifting quality of the crane, the rear outrigger becomes essential to ensure that the vehicle can handle the load safely. ထို့ အပြင်, in other special scene operations such as working on slopes or in areas with limited space, the rear outrigger can make a significant difference in ensuring the success and safety of the lifting operation.
Do you now fully understand the function of the rear outrigger? The decision to install the rear outrigger or not can be made based on several factors such as the operation site, vehicle size, and the nature of the lifting tasks. ဥပမာအားဖြင့်, if the vehicle is frequently used in areas with stable and flat ground and the lifting requirements are relatively light, the rear outrigger may not be necessary. သို့သော်, if the vehicle is expected to operate in uneven terrains, soft ground, or when handling heavy loads, installing a rear outrigger can be a wise choice.
နိဂုံးချုပ်အားဖြင့်, the rear outrigger of a ထရပ်ကားတပ်ဆင်ထားသောကရိန်းplays a crucial role in ensuring the safety and effectiveness of lifting operations. By providing rear support and distributing the load, it enhances the stability of the vehicle and allows for more precise and controlled lifting. Understanding the different types of rear outriggers and their applications can help operators make informed decisions and select the most suitable configuration for their specific needs.
