Usage: Utilizing Crane Load Charts for Mechanical Handling Studies

Introduction
Crane load charts are a critical resource for ensuring the feasibility of lifts in mechanical handling studies. This guide explains how to utilize the load charts provided on your site, emphasizing the importance of safety and conservative assumptions in design. Our load charts provide a reliable foundation for mechanical handling studies. By utilizing these resources and adhering to safety practices, users can confidently evaluate lift feasibility.

Understanding Mechanical Handling Studies

Mechanical handling studies verify the feasibility of a lift under specific conditions but do not replace detailed lifting plans. The load charts provided ensure compatibility across various crane brands by presenting conservative values, such as the largest turning radius or shortest boom.

Steps to Use Crane Load Charts

1. Determine the Load Radius

• Identify the horizontal distance between the crane’s center of rotation and the load (load radius).
• Using the nearest (or otherwise optimal) position of the crane, in Navisworks you can easily measure the radius.
• Locate the radius on the load chart to proceed.

2. Interpret the Crane's Lifting Capacity

• Match the load radius to the lifting capacity on the chart.
• Review both gross and net capacities to account for deductions like accessory weights.
• Note whether capacities are specified for operation over the front, rear, or 360-degree rotation.

3. Verify the Crane Configuration

• Ensure the chart aligns with the crane setup provided in the design files (e.g., with or without outriggers or stabilizers).
• Confirm the setup and environmental factors correspond with the specified capacity conditions.

4. Factor in Environmental Conditions

• Assess ground slope, soil stability, and wind speed, as these affect the crane’s stability.
• Apply additional safety margins for lifts at greater heights or in challenging conditions.
