The UNIMA 4 ultra-compact tamping machine presents an economical alternative to manual surfacing work using backhoes or hand tampers, coupled with manual lifting and lining processes. It incorporates a comprehensive 3-point lifting system and an ALC-guided 3-point lining system. This integrated approach allows for the consolidation of tamping, leveling, and lining into a single step, ensuring a swift and cost-efficient operation. This not only enhances accuracy and safety but also minimizes the need for manual labor, thus optimizing overall efficiency.
