Bộ căng đai (Hệ thống lò xo / Bôi trơn)

The WIRTGEN crawler units are designed to translate motive power into powerful feed during the milling process even in tough everyday site conditions.

Shape and dimensioning of all parts are precisely matched to the chain and ensure both effective power transmission and accurate tracking stability. The materials used guarantee a long service life and high functional reliability. Preassembled idler units and tensioner systems permit rapid replacement, thus boosting the machine’s availability.

1 Powerful and long-lasting. The perfectly adapted drive sprocket made from hardened, highly wearresistant cast steel provides a long service life and optimum power transmission.

2 Low-noise driving performance is achieved thanks to chain slide bars made of self-lubricating polyamide.

3 Insensitive to impacts maintenance-free hydraulic tensioner ensures that the tensioning pressure is always correct.

4 Permanent tracking stability and a long service life are assured thanks to a hardened guide system.

5 The wear-resistant idler is lubricated for life and ensures precise track guidance.
