Track tensioners — Track adjusters for mini excavators

• Impact absorption: Trasteel Track tensioners are built to withstand and dampen shocks during daily operation, reducing stress on the rubber track and the rest of the undercarriage.
• Consistent tension: The combined spring and grease system keeps the track properly tensioned at all times, even under intensive urban work or repetitive movements.
• Compact design: Optimized size for easy integration in the limited space of mini and midi excavators.
• Compatibility: Available for a wide range of compact machinery configurations with Trabber rubber tracks or other brands.

Recognizing common tensioner failures

Identifying issues with the tensioning system early helps avoid major damage to the track or idler wheel. Typical warning signs include:

• Loose track: If the tensioner rod is fully extended and the track remains slack, the system may be at its limit or have an internal failure.
• Blocked tensioner: If the track stays tight without adding grease, the internal spring or cylinder may be broken.
• Visible leaks: Grease or oil on the outside of the tensioner indicates a loss of sealing, preventing proper pressure retention.

Basic maintenance for light equipment tensioners

Simple but regular maintenance ensures proper tensioner performance and prevents unnecessary wear:

• Tension check: Visually inspect track tension at the start of each workday, especially in high-vibration applications.
• Leak inspection: Watch for grease or dirt buildup on the tensioner body — a sign of damaged seals.
• Planned replacement: Replace the tensioning unit if clear wear signs appear, to avoid damage to the idler or rubber track.

• Grease-based tension system: The cylinder is filled via a grease nipple, applying pressure to the internal spring and automatically adjusting track tension.
• Reinforced coil spring: Provides the force needed to keep the track correctly tensioned at all times, even during repetitive work cycles.
• Safety end stop: Prevents the rod from coming out if the tensioner reaches maximum extension, protecting the system from overload.
• Sealed, durable design: Tensioners are sealed to block dirt, mud and moisture, ensuring long life even in tough conditions.
• Guaranteed compatibility: Trasteel Track manufactures models for a wide range of mini and midi excavators, ensuring precise and reliable installation.

• Extended use with incorrect tension: Too little or too much track tension accelerates wear on the tensioner, rod and idler wheel.
• Lack of periodic checks: Not inspecting visually or monitoring grease pressure can lead to unnoticed internal failures.
• System contamination: Dirt, mud or water entering through damaged seals shortens the life of the cylinder and spring.
• Harsh working conditions: Abrasive materials or frequent impacts can cause deformation or early leakage.
• Undercarriage misalignment: Incorrect installation or uneven wear creates abnormal stress on the tensioner and its mountings.

To extend the life of the tensioner and the entire undercarriage, follow recommended maintenance intervals, act on any failure signs, and always use compatible components like Trabber rubber tracks.
