Equipment Catalog Overview

This document is a technical catalog from ROZZI SPA presenting specifications for various models of grabs designed for handling logs and diverse materials. The catalog includes detailed technical data, dimensions, and operational parameters for each model.

1. Models and Specifications

The catalog lists multiple grab models, identified by codes such as R50/250, R50/350, R50/225, R50/427, R50/327, and others (e.g., R103A, R104A, R102, R105F, R105A, R104F). Each model is characterized by the following parameters:

• Surface Area (S): Ranges from 0.2 to 0.4 m², indicating the grab's contact or operational surface.
• Weight: Varies between 115 kg and 250 kg depending on the model.
• Operating Pressure: Hydraulic pressure requirements range from 180 bar up to 300 bar.
• Oil Flow Rate: Hydraulic oil flow rates vary from 800 l/min to 2000 l/min, specifying the hydraulic system capacity needed.
• Lifting Capacity: Load handling capacity is provided in kilograms, with values such as 630 kg, 790 kg, 1500 kg, and up to 2000 kg depending on the model.

2. Dimensions

Each model includes detailed dimensional data labeled A, B, C, D, L, and F, representing physical measurements in millimeters. For example, the R50/250 model has dimensions such as A=1310 mm, B=60 mm, C=790 mm, D=680 mm, L=390 mm, and F=530 mm. These dimensions are critical for fitting and operational compatibility with machinery.

3. Functional Description

The grabs are designed primarily for the handling of logs and various materials, suitable for forestry and industrial applications. The catalog emphasizes versatility in material handling, with multilingual descriptions confirming their use for logs and diverse materials.

4. Operational Parameters and Recommendations

• Hydraulic Pressure: Ensure system pressure matches the specified bar rating for each model to guarantee optimal performance and safety.
• Oil Flow: Hydraulic systems must provide the required oil flow rate to maintain grab efficiency.
• Weight Considerations: The weight of the grab affects the overall machinery load and should be considered in equipment selection.
• Dimension Compatibility: Verify the grab dimensions against the host machine to ensure proper installation and operation.

5. Summary Table Highlights

The catalog includes tabulated data summarizing the key parameters for each model, facilitating comparison and selection. Critical parameters such as surface area, weight, pressure, oil flow, lifting capacity, and dimensions are presented side by side for ease of reference.

Conclusion

This equipment catalog provides comprehensive technical data essential for selecting the appropriate grab model for log and material handling tasks. It highlights critical operational parameters and physical dimensions to ensure compatibility and performance in forestry and industrial applications.
