Introduction of V-series steering product.
31
Sauer-Danfoss steering Unit
Introduction
• Introduction:
– V-series is a lower cost steering unit (20-30% below OSPC); withlower performance expectations, while maintaining high Qualitymanufacturing processes in production, to maintain consistancyand reliability over the machine life.
– Goal is to increase market share globally.
– Initially target markets are India, China, but with high focus on the rest of the world where volume machine production is emerging.
– Sales focus started Q2 (2012) with larger OEMs.• Already working with some of the target customers globally.
– General release for lower volume customers and Distribution planned for the end 2013.
