The Under-Sleeper Beam RM80 is a key structural component specifically designed and manufactured for the RM80 Full-Section Under-Sleeper Ballast Cleaning Machine. Engineered for major and medium railway track maintenance operations, it undertakes the functions of transferring and supporting the equipment's self-weight and excavation loads, while efficiently transmitting traction power. It serves as the fundamental guarantee for the equipment's stable operation and high-efficiency performance.
The under-sleeper beam serves as the core platform connecting the bolster and side beams and mounting the vibration damping system. It is subjected to long-term immense composite vertical, longitudinal, and lateral loads from the rails, the car body, and ballast cleaning operations. Its performance reliability is directly linked to the operational stability, work safety, and service life of the main structure of the entire ballast cleaning machine.
Superior Wear Resistance
During operation of the RM80 ballast cleaning machine, the under sleeper beam is constantly exposed to hard ballast and compacted bed materials. This product utilizes high quality materials with surface strengthening treatments, achieving a wear rate 40% lower than that of ordinary cast iron components. It supports prolonged continuous ballast cleaning operations, reduces the frequency of part replacement, helps maintenance departments lower operation and maintenance costs, and avoids unplanned downtime during work.
High-Load Design Ensures Safety During Heavy-Duty Operations
The product adopts an integrally cast structure and undergoes precision structural mechanics optimization, effectively avoiding stress concentration and preventing premature fatigue cracks in critical areas. This design significantly reduces the risk of deformation or fracture during operation, ensuring the structural stability of the ballast cleaning machine under heavy-load conditions and enhances the operational safety factor of the equipment.
Precise Fit, Streamlined On-site Installation
Designed with molds tailored precisely to the installation dimensions of the RM80 ballast cleaning machine, the positional tolerance of mounting holes is controlled within ±0.5 mm. On site assembly requires no additional grinding or hole enlargement, making replacement and installation convenient and fast. This significantly shortens maintenance time during railway "maintenance window" closures and improves the turnover efficiency of track maintenance equipment.
Corrosion and Weather Resistance for Demanding Outdoor Conditions
Railway operations often face rainy, snowy, humid (coastal lines), or low-temperature freeze-thaw environments. This product offers outstanding salt spray corrosion resistance, with a service life far exceeding that of standard coated products. This characteristic effectively reduces maintenance requirements for equipment in harsh conditions, contributes to reduced long-term operational costs, and ensures stable equipment performance in complex climates.
Compatible Models: Specifically designed for the RM80 ballast cleaning machine and its improved models within the same series that share the bogie design.
Functional Role: As a core load-bearing and connecting component of the ballast cleaning machine’s bogie, it supports the car body weight, mounts the vibration damping system, and transmits various dynamic forces generated during operation and working processes to the wheelsets and rails.
Recommendation: Before planning to undertake key projects such as ballast cleaning in long tunnels, track bed remediation in large marshalling yards, or high-frequency cross-department relocation operations, it is advisable to prioritize inspection of this component and perform preventive replacement if necessary to mitigate potential risks beforehand.
Is this under-sleeper beam only compatible with the RM80 ballast cleaning machine?
It is primarily designed for the RM80 full-section ballast cleaning machine, and specifications can also be customized upon request to fit models within the same series (such as the RM80-UHR).
Are special tools required for replacement?
No special tools are needed. The product retains the original installation hole positions and bolt specifications, allowing disassembly and installation to be performed using standard hydraulic tensioners or torque wrenches. It is recommended that the operation be carried out by technicians qualified in large-scale mechanical maintenance.
How can I determine whether the under-sleeper beam of my RM80 ballast cleaning machine needs to be inspected or replaced?
It is recommended to prioritize inspection of the under-sleeper beam under the following circumstances:
1. When the equipment exhibits persistent unexplained shaking or abnormal vibration during operation;
2. During regular major or medium overhauls, as a key structural component subject to non-destructive testing;
3. If associated hydraulic dampers frequently fail, or if the coil springs under the sleeper show abnormal wear or fracture, the mounting base (i.e., the under-sleeper beam) should also be examined for potential issues.
Routine visual checks should be conducted for visible cracks, severe corrosion, or deformation at critical areas of the under-sleeper beam.
