🧮 Quick Formulas

Per-Leg Tension:

T = (Load ÷ Legs) × Factor

Max Safe Load:

L = (SWL ÷ Factor) × Legs

Utilization:

U = (Gross ÷ Capacity) × 100%

Safety Rule:

Never exceed 90% utilization

✅ SAFE CONFIGURATION

💡 Quick Tips:

60° is the standard safe angle for most lifts
Never lift below 30° - tension doubles compared to 60°
4-leg lifts on rigid loads only use 2 legs effectively
Always account for rigging weight in total load

💡 Planning Tip:

Choose the scenario with lowest utilization (<75%) for safety margin. Shorter radius=higher capacity but may require repositioning.

Safety Practices for Lift Operations

Critical requirements for all lifts

🎯 3-3-3 Rule - Trial Lift

300mm

Height

3 sec

Hold

3m

Distance

Check load stability, rigging integrity, and crane balance before full lift.

📏 Operational Clearance

Lift load only high enough to clear obstacles (10-20% margin).

Minimize potential energy during travel.

📊 Load Chart Compliance

Never exceed manufacturer's limits.

Verify boom/angle capacity and radius.

⚡ Electrical Hazards

Min. distances: 900mm (≤750V), 3.6m (750V-100kV)

💨 Wind Conditions

Typical limit: 20 mph (32 km/h). Monitor continuously.

🛑 CRITICAL: Ensure outriggers fully extended on stable ground. Verify boom angle/radius against load chart. Stop immediately if unsafe conditions observed.
