1. Overview

This document details the technical specifications of EFFER crane models including the 655, 575, 470 series and others. It covers model configurations, mechanical parameters, load capacities, dimensions, and operational guidelines essential for crane selection and safe operation.

2. Model Configurations and Mechanical Parameters

Cranes are categorized by the number of boom sections (e.g., 3S, 4S, 5S, 6S, 8S, 9S) and jib attachments (e.g., 5S+JIB, 6S+JIB). Key mechanical parameters include:

• Operational angles (txm): Typically ranging from 40° to 57°, with jib configurations rated at 10° or 20°.
• Dimensions: Lengths and widths generally around 2465 mm to 8710 mm, consistent across models.
• Weight: Structural weights approximately 26 tonnes for standard models.

3. Load Capacities and Reach

Load capacities are provided in kilograms and pounds, with reach distances in meters and feet. Load decreases as reach increases. Examples include:

• EFFER 655 3S: Max load ~18,735 kg at 2.92 m, decreasing to ~5,800 kg at 10.31 m.
• EFFER 655 6S: Max load ~17,800 kg at 2.92 m, decreasing to ~3,170 kg at 14.91 m.
• EFFER 575 3S: Max load ~17,535 kg at 2.92 m, decreasing to ~5,135 kg at 10.31 m.
• EFFER 470 4S: Max load ~9,400 kg at 4.55 m, decreasing to ~3,910 kg at 10.31 m.

Jib variants extend reach but reduce load capacity accordingly.

4. Mechanical Torque and Dimensions

Torque values range from approximately 296,800 lb*ft to over 413,700 lb*ft depending on model and configuration. Boom lengths and offsets typically measure between 97 and 105 inches.

5. Variants and Options

• Standard Models: Basic configurations without jib.
• Jib Variants: Models with jib extensions for increased reach.
• Light and Heavy Duty Versions: Available for some 6S+JIB models, affecting weight and load capacity.

6. Operational Angles and Limits

Operational angles (txm) influence the crane’s working envelope and load charts, with jib models typically limited to 10° or 20°.

7. Key Recommendations and Usage Notes

• Load capacity decreases with boom extension; operators must consult load charts for safe operation.
• Jib attachments increase reach but require attention to reduced load capacities.
• Selection between Light, Heavy Duty, and standard versions should be based on application needs.
• Dimensions and weights are critical for transport and installation planning.

8. Summary Tables and Data Interpretation

Extensive tabular data correlates load capacities, reach distances, and mechanical parameters for each model and configuration, serving as essential references for engineers and operators.

9. Additional Technical Data Summary

Load capacities range from approximately 300 kg (660 lb) to over 8,700 kg (19,210 lb), with reach distances from 2.36 m (7’8") up to nearly 30 m (100 ft). Models are identified by boom sections and jib configurations, with maximum torque values and weights typically around 26 tonnes.

10. Recommendations and Best Practices

• Select crane models based on required load and reach, balancing capacity and extension length.
• Heavy Duty versions are suited for higher loads at shorter reaches.
• Strict adherence to load charts and torque limits is essential for safety.
• Optional display systems may improve operational safety and precision.

11. Limitations and Safety Considerations

• Load capacity decreases with increased reach; always consult specific load charts.
• Operating angles and torque limits must not be exceeded to maintain structural integrity.
• Environmental and installation factors, though not detailed, should be considered in planning.

This summary consolidates critical technical specifications and operational parameters for EFFER crane models and jib configurations, supporting informed selection and safe operation.
