Wire Braid vs. Spooled: Which Excavator Hose is Right for Your Equipment?
Oil hoses are crucial for excavator operation, transporting oil to ensure the proper functioning of all excavator components. Steel wire hoses and spiral-wound hoses are two common types of excavator hoses. Choosing the right hose for your equipment requires a thorough understanding of their characteristics.
Steel wire braided hoses consist of a steel wire braid layer with an inner and outer adhesive. The braiding process makes them extremely flexible. They can bend to a certain degree without compromising performance, a key advantage in the demanding working environments of excavators. In areas where frequent bending is required, such as excavator arm joints, steel wire hoses easily adapt to angle changes, reducing the risk of damage from bending. Furthermore, the manufacturing process for steel wire hoses is relatively mature and the cost is relatively low, making them a good choice for users with limited funds.
However, braided steel wire hoses also have limitations. Due to the characteristics of their braided structure, their pressure capacity is relatively limited. Under high-pressure conditions, braided steel wire hoses can suffer from problems such as packing and water seepage. This limits their use in some large and high-pressure excavators.

In comparison, wire-wound oil hose uses a wire-wound process, with two layers of steel wire tightly intertwined to form a strong, pressure-resistant structure. This allows it to withstand high pressures, exceeding the hydraulic pressure of braided wire hose. In high-pressure environments such as excavators and deep-sea mining equipment, wire-wound oil hose can stably transport oil, ensuring the proper operation of the equipment.
Wire-wound oil hose also offers improved fatigue resistance. Its winding structure effectively distributes pressure, effectively preventing fatigue damage during long-term, high-intensity operation and extending the service life of the hose. However, wire-wound oil hose is not suitable for this application. It is relatively inflexible, requires high technical skills from construction teams, and is relatively expensive.
When selecting excavator oil hose, customers need to consider a variety of factors. For small excavators or low-pressure equipment, wire-wound oil hose, with its advantages of good toughness and low cost, is a suitable choice. It can meet the basic requirements of the equipment and reduce customer costs.
However, for large, high-performance excavators, especially those operating in high-pressure and high-intensity environments, wire-wound oil hose is more suitable. Despite the higher cost, its high pressure and excellent fatigue resistance ensure efficient system operation and reduce equipment failures and downtime caused by tubing issues.
In addition, the frequency of equipment use and the extremes of the operating environment are also important considerations. If the excavator is frequently used and operates in harsh environments, such as high temperatures and sand, the fatigue resistance of wire-wound tubing may make it a better choice.
In summary, both braided and wound tubing have their advantages and disadvantages. When choosing excavation tubing, users should fully understand the equipment's needs, operating environment, and budget, consider the pros and cons of both options, and make the ideal choice to ensure efficient and effective operation of the excavation equipment.
