What materials are typically used in the boom of a high-performance cement pump truck for sale? Let's take a closer look at the world of cement pump truck booms.
1. Role of the boom
Some may wonder, what is aoom and what kind of impact does it have on the performance of a cement pump truck for sale? As the most important structural component of a cement pump truck, the quality of the arm is a direct factor in evaluating the overall quality of the cement pump truck, as well as its ability to perform as specified. Those who understand the industry know that the lifespan of the arm directly determines the lifespan of the concrete pump truck. Therefore, when designing the boom, cement pump truck manufacturers need to exercise caution. It is not just about pursuing a longer boom length to impress others, nor is it about sacrificing arm length for stable performance. Thus, when designing the boom, the focus should be on the choice of materials, as only lightweight materials with sufficient strength can support the ambitious goal of an extra-long boom.
2. Weight is not everything for the boom!
According to relevant research data, for every 1% reduction in weight of the boom, there can be a fuel consumption reduction of around 0.8-1.1% for the engine. Therefore, for a concrete pump truck, heavier does not necessarily mean better for the boom; of course, using materials like carbon fiber that are too lightweight in pursuit of a lighter boom is also not advisable. The arm material must be lightweight enough, but this choice is not an easy one to make.
3, How to achieve lightweight?
It is well-known that the longer the arm of the cement pump truck, the higher the pressure it can withstand. It is worth mentioning that the pressure on the arm during horizontal pumping is 3-4 times higher compared to vertical pumping. Therefore, in order for the concrete pump truck to pump to greater heights, the arm must be made with even higher strength steel. News reports indicate that currently, there are only four countries in the world capable of manufacturing this type of high-strength steel, with China ranking among the top in terms of both quality and production output. This is one of the main reasons why cement pump trucks in China have long held a leading position in the world market. Based on market data, it can be seen that the use of high-strength steel above 1000 megapascals has become the norm for long-boom pump trucks in China.
3. Cutting-edge boom technology
Currently, mainstream concrete pump truck brands in China have several advantages in arm production:
- The use of imported ultra-high strength steel plates
- QPQ surface modification technology
- X-ray flaw detection
- Long stroke pumps adopting intelligent biologically-inspired 6RZ technology
- External connecting rod Stetter technology
- Heart-crossing pipe external suspension design
- Composite double-layer pipe technology to improve wear resistance, resulting in an average lifespan of 50,000 cubic meters for the concrete pump truck.
These cutting-edge technologies are important benchmarks to consider when selecting a cement pump truck for sale.
