Diaphragm wall load lifting grab SG70

electro-hydraulic

Overview

• Manufacturer: supplier of specialised equipment for underground wall construction.
• Low consumption and high efficiency
  The electromechanical-hydraulic integrated system is matched for reduced fuel consumption (≈25%) and improved construction efficiency (≈15%) versus comparable models.
• Stable and reliable
  Double-winch integrated configuration with single-row rope reel for the grab extends wire rope service life. Controlled hose winch feeding reduces extrusion and wear, extending grab tubing life by up to 60%.
• Operator-oriented design
  Equipped with an air-suspension seat and an optimized spatial layout to improve operator comfort and facilitate maintenance.
• Digital control and monitoring
  Visual control and monitoring system displays equipment status and provides automatic alarms for abnormal conditions.
• Data management
  Digital management system records and stores construction dynamic parameters in real time.
