History of cooperation within the project and pain points in selection
The Qingdao Zhonghong FAMBITION 2-cubic underground scraper excavator is mainly used for ore transportation in underground mines, mud cleaning, loading and unloading operations using equipment, and other operating conditions. The operating conditions are extremely harsh: the underground road is NARROW and CUT UP, the road surface is muddy and stagnant year-round, the impact of ore gravel on the ground is very great. the dust concentration is often high, and the air is humid and corrosive.
In the early stages of equipment development, the original support drive axles had a number of industry-typical shortcomings: wheels were very slippery on slick roads, with insufficient traction, affecting operational efficiency; the conventional braking system had poor dust and moisture resistance and was prone to corrosion, posing risks of braking failure and hidden dangers during prolonged underground operations; the seal design was weak and susceptible to mud and slurry intrusion, leading to oil leaks, bearing wear, and axle housing damage; the housing lacked sufficient rigidity and was prone to deformation and abnormal noise under heavy-duty conditions, resulting in high equipment downtime and maintenance frequency, which severely impacted the construction progress of terminal mining enterprises and limited equipment manufacturers' ability to improve overall equipment quality.
To fully address the above issues, Qingdao Zhonghong Company contacted several manufacturers and conducted multiple rounds of product comparison tests, rigorously evaluating various parameters such as product structure, adaptability to operating conditions, durability, failure rate, manufacturer reliability, and after-sales warranty. Ultimately, they selected the special front axle of Shandong Lutong's Underground Scraper CY20 as the key auxiliary component for the entire machine to complete a comprehensive product upgrade cycle.
Advantages of the main product of the front axle of the well scraper CY20
In combination with the extreme operating conditions of underground scrapers, Shandong Lutong purposefully optimizes the core performance of the CY20 drive axle. All designs are based on four main principles: "reducing failures, improving efficiency, safety, and durability," which fully meet the high standards required for mining equipment.:
1. Front differential without slipping, ensuring full traction on complex roads
The standard front axle configuration includes a high-quality industrial limited-slip differential, which eliminates the drawbacks of a traditional open differential. It can automatically lock and prevent slipping on muddy, soft, and uneven underground roads, effectively solving the problem of wheel spin and jamming on one side, continuously providing stable traction, significantly improving the off-road capability and operational efficiency of scrapers on complex road surfaces, and perfectly adapting to the needs of low-frequency road conditions in mines.
2. Wet-type parking brake system with wheel-mounted locking, integrated braking, safety, and compliance with underground operation requirements
It is equipped with high-quality positive-stop spring brakes and wet hydraulic brakes, which combine two functions—service braking and parking braking—ensuring fast brake response and uniform braking force. The fully enclosed wet design completely isolates erosion caused by underground dust, dirt, and sludge, prevents brake damage and rust, and consistently maintains stable braking performance. It fully meets the safety requirements for operating underground mining special equipment and guarantees the safety of the entire machine from the level of the core component.
3. High-quality floating seal design on the wheel side, ensuring maximum sealing and leak protection.
Given the corrosive conditions associated with high humidity, dust, and dirt underground, the floating lip seal design on the wheel side and multiple protective sealing structures are specifically engineered to completely block the ingress of external contaminants into the axle housing, effectively solving the common problems of oil leakage, ash ingress, bearing wear, gear rust, and other common issues of traditional drive axles during prolonged underground operations, which significantly reduces equipment failure frequency and downtime, and also extends the overall service life of the drive axle.
4. One-piece cast steel axle housing + two-stage reduction transmission, providing high load-bearing capacity under heavy-duty production conditions.
The bridge housing is made of integral cast steel, with no gaps in the connection and high rigidity. It withstands high-frequency impacts under heavy operating conditions and gravel impacts during mining, and is not prone to deformation or cracking. The precision two-stage reduction transmission system ensures low transmission losses, high torque, and stable power transmission. It is ideally suited for the intensive working mode of underground scrapers with frequent start-stop and heavy-duty movement, and its energy performance far exceeds that of ordinary drive axles with the same specifications.
5. Imported range of main accessories, stable quality and fatigue resistance
The main components of the drive axle gears, bearings, seals, and brakes are made from products of world-renowned brands. After intensive fatigue testing, they possess excellent wear resistance, aging resistance, and impact resistance. They are not easily damaged during prolonged high-frequency operation. The stability and durability of the entire machine are significantly improved, and the after-sales maintenance costs of the main equipment are reduced compared to the original.
6. Precise model adaptation, no need to change the direct fit
The CY20 drive axle is specially designed for underground scrapers with a volume of 2 cubic meters. The installation dimensions, power parameters, and assembly interface perfectly match the design of the Qingdao Zhonghong FAMBITION machine. Equipment manufacturers do not require additional modification, debugging, and adaptation, as well as direct series assembly and fitting, which significantly saves time. Product iteration time and transformation costs for the manufacturer.
Landing effect and cooperation results
Since the start of mass production, the 2 m³ underground scraper from Qingdao Zhonghong, equipped with the Shandong Lutong CY20 drive axle, has been put into operation in batches at major metal and non-metallic mines. After long-term verification of operating conditions, the overall performance of the entire machine has been significantly improved: the frequency of equipment slipping, brake failures, and oil leaks has been greatly reduced, the continuous operating time of the equipment has increased significantly, the frequency of downtime and maintenance has decreased by more than 60%, and the reputation among end users has improved considerably.
This successful cooperation not only helped Qingdao Zhonghong improve the quality and market competitiveness of its underground scrapers, but also fully confirmed the stability, reliability, and adaptability of Shandong Lutong mining drive axles under extremely severe operating conditions. For large manufacturers of mining, engineering, and agricultural machinery, choosing Shandong Lutong means not only choosing a high-quality drive axle, but also choosing a set of well-considered, reliable, and long-term solutions for supporting core components.
