Specialized XUL518 left-side fuel tank for confined spaces: Eliminates the three constraints of space occupation, instability and difficult maintenance.
Product Overview
In underground mining operations in confined spaces, the unreasonable layout of fuel tanks is prone to scraping the tunnels, causing oil contamination and power interruption, and requiring significant repositioning of equipment for maintenance, which highlights the prominent problems such as equipment damage, project delays, and a sharp increase in operation and maintenance costs. Based on the core needs of confined space operations, Xiangyu Baoyuan has launched the XUL518 Left fuel tank for confined spaces exclusive accessory, and together with Excavator Parts, Tower Crane Accessories, Aerial Work Vehicle Parts, and Underground Loader Parts, has constructed an accessory ecosystem for confined space operations. This product corresponds to the Product Model: XUL518. Its size has been precisely optimized to 2975*940*1616mm. Through innovative space adaptation and strengthened design for working conditions, it fundamentally solves the industry's pain points, ensuring the flexible operation and stable running of equipment in confined spaces, and significantly reducing the difficulty of operation and maintenance, injecting efficient and safe new momentum into underground confined tunnel mining operations.
Product Parameter
In the mining scenario of the confined underground space, the value of the left oil tank has already surpassed the mere "storage of fuel", becoming the core element that determines the passability, operational stability and maintenance efficiency of the equipment. Its main function is to provide a stable fuel supply for the XUL518 underground loader, while through scientific structure and size design, it avoids the risk of rubbing against the tunnel walls and support structures, and is suitable for narrow tunnels with a section of 3-4.5 meters. The size of 2975*940*1616mm is not a simple numerical setting, but the optimal solution calculated by xiangyu baoyuan based on thousands of sets of data from confined tunnel operations - the length and width take into account the fuel storage capacity (which can support the equipment to operate at high intensity continuously for 12 hours) and the lateral occupied space of the equipment, and the height is adapted to the center of gravity design of the XUL518 body, avoiding the equipment's center of gravity shifting due to an excessively high oil tank, further enhancing the safety of operations in confined spaces.
From the perspective of the innovative design core, the left fuel tank breaks away from the traditional "rectangular and regular" shape of the fuel tank and adopts an innovative structural design of "arc-shaped side edges + low-level adhesion". To address the pain point of potential scratches on the sides of narrow alleys, the side edges of the fuel tank adopt a 15° arc-shaped transition design. Even if the equipment turns to the extreme in the alley, it can avoid hard collisions between the sharp edges and the alley walls or the support steel scaffolding, reducing the dual risks of fuel tank deformation and alley damage. At the same time, the fuel tank adopts a low-level adhesion installation structure, which precisely fits the chassis of the XUL518 body. This not only reduces the occupation of longitudinal space but also improves the driving stability of the equipment in slippery and narrow alleys through the design of a lower center of gravity. Compared with traditional fuel tanks, it reduces the risk of equipment overturning by more than 45%.
To address the problem of inconvenient maintenance in confined spaces, this innovative fuel tank adopts a "front-side integrated maintenance module" design, breaking the traditional limitation where maintenance of the tank needs to be carried out from the side or bottom of the equipment. The core maintenance components such as fuel filters, level monitors, and discharge valves are centrally integrated in the easily accessible area on the front side of the tank. Operators do not need to enter the narrow gaps between the equipment and the wall of the tunnel; they can complete the entire maintenance process, including oil inspection, filter replacement, and impurity discharge, on the front side of the equipment. The single maintenance time has been shortened from the traditional 1.5 hours to within 30 minutes. What is more noteworthy is that the level monitor is equipped with a visual intelligent display function, which, in combination with the interlinked warning system in the equipment cab, can provide real-time feedback on the oil level and oil quality status, avoiding problems such as insufficient oil supply causing equipment shutdown or deteriorated oil quality due to restricted visibility in the confined space.
In terms of adaptability to working conditions, the left fuel tank adopts the design concept of "double-layer protection + sealing upgrade", which perfectly suits the extreme working conditions in underground spaces, such as being damp, dusty, and prone to collisions. The outer layer is made of high-strength wear-resistant alloy steel, which is treated with sandblasting rust removal and cathodic electrophoretic coating. It can resist the impact of mineral debris and the erosion of underground damp water vapor, and its service life is 2.5 times longer than that of ordinary fuel tanks. The inner layer is coated with anti-corrosion coating, which effectively prevents the wear of the inner wall of the fuel tank by impurities in the fuel and reduces the risk of fuel contamination. At the same time, the sealing system of the fuel tank uses military-grade sealing rings and a double-sealing structure, which can withstand the vibration and shock generated by frequent jolts of the equipment in the narrow space, completely eliminating the problem of fuel leakage and avoiding potential safety hazards such as underground fires caused by fuel leakage, in line with the strict safety regulations of underground mining operations.
application scenarios
This oil tank is widely applicable in various underground confined space mining operations - in the deep exploration tunnels of metal mines, the branch mining tunnels of non-metal mines, etc., in the narrow tunnels with a 3-4.5m cross-section, its spatial adaptability and operational stability have been fully verified; in non-mining types of underground confined space projects such as urban underground pipe galleries construction and small tunnel excavation, the XUL518 equipment can also be adapted to complete material transportation operations. From the perspective of industry development, as underground mining extends to deeper areas, the proportion of narrow cross-section tunnel operations continues to increase. The innovative design of spatial adaptability and performance enhancement of this oil tank precisely aligns with the industry's "narrow body, efficient, and safe" development trend, and has become a key supporting component for the upgrade of equipment in underground operations in confined spaces.

Tips:
During installation, it is necessary to fix the XUL518 body precisely according to the positioning reference mark, to avoid affecting the equipment's center of gravity and the compatibility with the space due to installation deviation.
2. It is recommended to clean the surface dust of the operation module every 200 hours of operation, and check the condition of the seals to prevent impurities from affecting the monitoring accuracy and sealing performance.
