Scenario Analysis

Verify maximum safe load capacities based on sling angle and load factors.

1. Scenario Details

You are tasked with verifying the lift capacity for a load using a 4-leg sling configuration.

Equipment 4 x SWL Wire Slings
Lift Angle 90° (Vertical)
Sling Capacity 15 Tonnes (Each)
Total Potential 60 Tonnes

2. Sling Diagram

Why 90° Matters

In this exercise, the slings are vertical (90°). This is the optimal configuration.

At 90°, the Load Factor is 1.000. This means 100% of the sling's strength goes towards lifting the weight, with no capacity lost to horizontal tension.

Tip: As the angle gets smaller (e.g., 30°), the load factor increases, drastically reducing the safe load.

3. Load Factor Guidelines

Select a row to see how different angles affect the multiplier. Lower angles increase tension significantly.

Angle vs. Tension Visualizer

Leg Angle	Load Factor	Efficiency
90° (Vertical)	1.000	100%
60°	1.154	~86%
45°	1.414	~70%
30°	2.000	50%

Calculation Logic

Calculate Total Potential

15T × 4 Slings = 60T

Identify Load Factor

Angle 90° = Factor 1.000

Apply Safety Formula

60T ÷ 1.000 = 60T

Maximum Safe Load

60.00 T
