Phase 1: Pre-Planning & Site Survey

Gather essential project information and conduct site assessment

Project Information

Ground Conditions (M5)

Site Survey Checklist

Ground Conditions

Proximity Hazards & Environment

Access, Egress & Setup

Public Safety & Control Zones

Personnel & Communication

Documentation & Emergency

Phase 2: Load Calculations

Calculate load weights, COG, and lifting accessories

🧮 Advanced Load Weight Calculator (M9)

Calculate weight for different load shapes and materials

📐 Centre of Gravity (COG) Determination (M10)

✓ For uniform cylindrical load: COG is at geometric center (midpoint of length).

📏 Lift Parameters

⚠️ Critical: Maximum radius is measured from crane slew centre to load COG. Verify with site measurements.

🔗 Lifting Accessories & Sling Tension Calculator

Angle between sling and vertical axis. 0° = vertical, 60° = max recommended

Additional Lifting Equipment

~5 kg each

Phase 3: Crane Selection & Ground Bearing

Select appropriate crane and verify ground bearing pressure

🏗️ Crane Selection & Specifications

💡 Quick Select: Choose a common crane model to auto-fill specifications, or enter manually below.

⚙️ Boom Configuration

⚖️ Ground Bearing Pressure (GBP) Calculator

Verify ground can support crane + load without settlement

🛡️ Outrigger Pad Specification

⚠️ Abort Criteria: >25mm settlement observed during 360° slew test = STOP operations immediately.

✅ Capacity Verification

📋 Important: Always verify against manufacturer's load chart. Boom length, jib, and counterweight affect capacity.

Phase 4: Lifting Plan Diagram

Create scale drawing with crane position and hazards

🎨 Diagram Requirements (RTITB M7)

📐 Diagram Dimensions

🎨 Interactive Diagram Builder

Create a professional site diagram using the drawing tools below. Select a template to start, or use tools to draw from scratch.

Templates include crane position, exclusion zones, and common elements
Scale: 1:100
Grid: 5m
💡 Tip: Use the drawing tools to create a professional site diagram showing crane position, load locations, exclusion zones, buildings, and overhead hazards. Export as PNG to include in your final plan.
