1. Model Identification and Basic Parameters

The document details technical specifications for multiple EFFER crane models, including series 365, 350, 305, 275, and 255. Each model is identified by section codes (e.g., 3S, 4S, 6S, 8S) and may include jib configurations (e.g., 4S+JIB 3S, 6S+JIB 4S HD), which influence performance and dimensions.

2. Key Technical Specifications

• Torque (txm): Expressed in degrees and lb*ft, indicating the crane's rotational torque capacity and operational limits.
• Dimensions: Provided in millimeters/inches for boom lengths, extensions, and mounting parameters, essential for installation and compatibility.
• Weight: Crane weights are given in kilograms and pounds, critical for transport and structural considerations.
• Load Capacities: Detailed load capacities at various outreach distances, in kilograms/pounds and meters/feet, defining safe lifting limits.

3. Model-Specific Highlights

• EFFER 365: Torque ranges 29.88°–32.27°, weights 3850–4825 kg; load capacity example: 3920 kg at 8.01 m (26’3") for 3S.
• EFFER 350: Weights 3615–4680 kg; torque approx. 31.44°–32.27°; multiple outreach load capacities detailed.
• EFFER 305: Torque 22.73°–27.14°, weights 3245–4050 kg; includes jib and heavy-duty variants.
• EFFER 275: Torque 22.32°–24.76°, weights 3245–4350 kg; load charts include jib and heavy-duty options.
• EFFER 255: Torque 21.97°–23.84°, weights 2985–3795 kg; jib configurations and detailed load capacities provided.

4. Load Capacity Tables

Each model section contains tables listing maximum permissible loads at specific outreach distances, presented in metric and imperial units. These tables are critical for ensuring safe crane operation within mechanical limits.

5. Dimensions and Structural Parameters

Comprehensive dimensional data includes boom lengths, extension lengths, and mounting dimensions in both metric and imperial units. These parameters are vital for installation planning and vehicle compatibility.

6. Configuration Variants

Models offer variants with jib attachments, light or heavy-duty versions, and optional configurations. These affect torque, weight, and load capacities, enabling customization for specific operational requirements.

7. Operational Angles and Limits

Torque angles (txm) and other angular parameters define operational limits and mechanical constraints for each model and configuration, ensuring safe usage within design parameters.

8. Summary of Critical Information

• Torque and load capacity decrease as boom length and outreach increase.
• Heavier models and jib-equipped configurations provide higher load capacities but increase overall weight.
• Dimensions and weights are crucial for transport, installation, and operational safety.
• Consulting load charts is mandatory to ensure lifting within specified outreach and weight limits.

9. Recommendations and Best Practices

• Select crane models and configurations based on required load capacities and outreach distances.
• Carefully consult load capacity tables to avoid exceeding limits at any boom extension.
• Consider weight and dimension constraints for transport and mounting compatibility.
• Use heavy-duty or jib variants when higher performance or extended reach is necessary.

10. Additional Technical Data Summary

The document also covers lifting equipment configurations with varying numbers of sections (2S to 6S) and jib options (JIB 2S to JIB 4S), providing weights, lengths, and load capacities in both metric and imperial units.

• Maximum lifting capacities range from approximately 2,500 kg (5,500 lb) to over 8,000 kg (17,900 lb).
• Reach lengths vary from about 6 m (20 ft) to over 21 m (70 ft), depending on model and jib configuration.
• Typical maximum torque values range from 20° to 22.5°, with boom lengths around 2,375 mm to 2,666 mm.

Load charts detail lifting capacities at various boom lengths and angles, illustrating the relationship between load weight and boom extension. Optional jib configurations extend reach and lifting capabilities but affect maximum load capacities.

11. Best Practices and Limitations

• Operators must adhere strictly to specified load limits at given boom lengths and angles to maintain safety.
• Use of optional jib configurations requires careful consideration of altered load capacities and reach.
• All measurements and capacities should be cross-checked with the specific model's load chart before operation.

This structured technical data supports safe and efficient crane selection, operation, and compliance with safety standards by providing comprehensive load, reach, and configuration parameters.
