Overview

This document provides comprehensive technical specifications and operational data for the MR 295 H16 tower crane, fully compliant with EN 14439 C25-D25 standards. It covers load capacities, structural components, ballast configurations, mechanical equipment, and power requirements, serving as a key reference for engineers and operators.

1. Load Capacities and Operational Parameters

• Maximum lifting capacity is 16 tonnes.
• Jib lengths vary from 30 m to 60 m, with load capacities decreasing as jib length increases.
• Load charts detail maximum permissible loads at various jib lengths and heights, ensuring safe operation within defined limits.
• Operational parameters, including wind profiles, conform strictly to EN 14439 C25-D25 standards.

2. Mast and Structural Reactions

• Mast reaction forces are specified for different mast heights, extending beyond 200 m, and various jib configurations.
• Data includes forces under both service and out-of-service conditions at multiple mast sections and anchorage points.
• Dimensions and weights of mast sections and connecting elements are provided to support assembly and structural integrity.

3. Ballast and Counterweight Specifications

• Detailed ballast weights and configurations are outlined for different mast and jib setups to ensure crane stability.
• Counter-jib and jib weights, including options for reinforced frames, are specified.
• Ballast supports and chassis components are dimensioned with weights critical for safe installation.

4. Mechanical Equipment and Power Supply

• Hoisting and luffing winches are described with power ratings, rope lengths, and lifting speeds.
• Power supply requirements are 400 V ±10%, 50 Hz, with kVA ratings provided for various winch models (e.g., 75 HPLTM, 100 LVF, 150 LVF GH).
• Control systems include a Power Control function that adjusts winch speeds based on available power to optimize performance and prevent overload.

5. Dimensions and Weights of Components

• Component weights range from several hundred to several thousand kilograms, essential for transport and assembly planning.

6. Standards and Compliance

• The crane meets EN 14439 C25-D25 standards for wind conditions, load handling, and structural safety.
• Electrical safety complies with IEC 60204-32 standards.

7. Operational Movements

• Hoisting: Vertical lifting operation.
• Luffing: Adjustment of the boom angle.
• Slewing: Rotational movement of the crane.
• Travelling: Horizontal translation of the crane.

8. Anchorage Frame Condition

The document highlights a loosened anchorage frame issue, indicating a potential structural or mechanical concern requiring immediate attention to maintain safety and stability.

9. Recommendations and Notes

• The document is a commercial, non-contractual reference; users should consult official instruction manuals for detailed technical guidance.
• Reinforced frame configurations are available upon request.
• Anchorage frames and fixing angles are specified to ensure secure installation.
• For further technical details or consultation, contacting the manufacturer or provider is advised.
