The rubber track is the standard drive system for mini excavators, compact loaders, and small tracked dumpers up to approximately 10 tons operating weight. Unlike steel tracks, it consists of a continuous rubber belt with vulcanized steel cord tension members and steel reinforcements as guide elements.
Advantages over steel tracks: no damage to asphalt, paving, and floor coverings, reduced vibration and noise, lower ground pressure. Disadvantages: shorter service life (typically 1,500–3,000 hours), sensitive to sharp-edged stones and metal parts, not adjustable for elongation. A new rubber track for a 5-ton mini excavator costs €800–1,500 per side.
Correct track tension is critical: too tight increases wear on rollers and drive sprockets, too loose can cause track slippage. Tension is adjusted via a grease tensioner on the idler wheel — check every 50 operating hours. Manufacturers such as Bridgestone, DRB, and Continental offer OEM and aftermarket tracks in numerous sizes.
