Is repairing rubber excavator tracks an option?

Repairing rubber excavator tracks is a topic that often comes up because maintaining heavy construction equipment can be costly, and operators are continually looking for ways to reduce expenses. Rubber tracks are commonly used on mini or compact excavators, and whether they can be repaired or not depends on several factors including the extent and type of damage, as well as the cost-effectiveness of the repair. Here’s a detailed look at the possibilities and considerations when it comes to repairing rubber excavator tracks.

Types of Damage

• Surface Cuts and Small Punctures: Minor surface cuts and punctures that do not impact the internal steel cording can sometimes be repaired with a specialized rubber track patch kit or sealant.
• Deep Cuts and Tears: More significant damage that exposes or damages the internal steel cording usually undermines the structural integrity of the track, making repair more difficult or impossible.
• General Wear: Normal wear and tear cannot be repaired; instead, it indicates that the track is nearing the end of its usable life span.

Repair Methods

• Patch Kits: For superficial cuts and punctures, repair kits available on the market can be used as a temporary fix. These kits often include a bonding material that vulcanizes the rubber for a seal.
• Sealants: Specialized adhesives or sealants applied to smaller damage points can extend the track’s use for a short period.

Professional Repair Services

• There are services that specialize in the repair of rubber tracks. They can apply heavy-duty patches and use techniques similar to those used for repairing tire damage.

Considerations for Repair

• Structural Integrity: If the internal structure of the track is compromised, repairing may not be safe or feasible. This kind of damage can lead to track failure, which may not only cause downtime but also create safety risks.
• Temporary vs. Permanent: Repairs are often not a permanent solution; they’re more of a stop-gap measure to extend the life of the track until a replacement can be arranged.
• Cost-Effectiveness: Consider the cost of repairs versus purchasing new tracks. If the track is near the end of its life or if the repair is a considerable fraction of a new track’s cost, replacement might be the more economical choice.

DIY vs. Professional Repair

• DIY: While do-it-yourself kits are suitable for minimal, non-structural damage, improper application can lead to further damage or fail to hold during operation.
• Professional: Professionals can assess the damage properly and have the right tools and materials for more reliable repairs.

Down Time

• How long the machine can be out of service will also impact the decision. Repairs will take time, and if the equipment is needed urgently, then a quick patch might be all that can be afforded in terms of time.

Safety First

• Safety should never be compromised. If there’s any concern that a repair might fail during use, especially in a way that could endanger operators or others on a job site, then replacement is always the better choice.

Conclusion
While minor and superficial damage to rubber excavator tracks can be patched or sealed, significant or structural damage typically necessitates track replacement. When assessing whether to repair or replace a damaged rubber track, consider the extent of the damage, safety, cost, and any potential downtime. For safety and long-term reliability, consult with a professional if you have any doubts about the extent of the damage or the feasibility of a repair. Remember, a temporary fix might get you through a job, but it’s not a substitute for replacing a badly damaged or worn-out track.
