Product catalog summary
Overview: This document outlines the technical specifications and features of a crawler crane model, focusing on its capabilities, design, and operational efficiencies. Key components discussed include the engine, hydraulic system, undercarriage, cab, winch, and crane equipment.
Specifications:
  • Engine: The crane is powered by a Cummins X12 (Stage V) engine, delivering 321 kW, with features like direct injection, turbo-charging, and reduced emissions.
  • Hydraulic System: It includes a multi-circuit system with variable displacement piston pumps, a maximum operating pressure of 330 bar, and a hydraulic tank capacity of 860 liters.
  • Undercarriage: The Star-Lifter wide-gage crawler design provides a robust travel drive and a spring-loaded multi-disk brake.
  • Cab: The Maxcab offers ergonomic features, automatic air conditioning, and safety options such as bulletproof glazing.
  • Winch: Features high-pressure-regulated adjustable hydraulic motors for optimal pulling force and speed control.
Features:
  • Control System: Utilizes the SENNEBOGEN control system for simplified diagnosis and maintenance.
  • Transport and Setup: Designed for easy transport and quick setup, facilitated by the ballast support system.
  • Operational Flexibility: Capable of operating under full load with minimal space requirements and flexible operation capabilities.
  • Safety and Usability: Equipped with safety valves, camera monitoring, and ergonomic controls to enhance usability.
Load Capacities: Detailed tables provide load ratings for various boom lengths and radii, considering factors like tilt angle and undercarriage track width. Load capacities may vary based on environmental conditions and equipment configurations.
Additional Notes: Specifications are preliminary and subject to change, with additional options available upon request. The document stresses the importance of following operating instructions for accurate load ratings and safe operation.
