Cabinet Weight

Understanding Cabinet Weight

Cabinet weight is fundamental to safe LED wall installation. Accurate weight calculations prevent structural failures and ensure safe rigging.

Weight Ranges by Type

**Indoor Rental Panels (500x500mm):**

• Standard: 7-10 kg
• Die-cast aluminum frames
• Designed for repeated handling
• Optimized for touring

**Fine-Pitch Panels:**

• Higher density: 10-15 kg
• More robust construction
• Precision alignment requirements
• Heavier power supplies

**Outdoor Panels:**

• Weatherproof: 20-40 kg
• Sealed enclosures
• Heavy-duty construction
• Larger power supplies

**Lightweight Designs:**

• Carbon fiber or magnesium: 5-7 kg
• Premium pricing
• Reduced rigging requirements
• Touring-optimized

Weight Calculation

**Basic Formula:** Total Weight = (Panel Weight × Panel Count) + Hardware + Cables + Safety Margin

**Example:**

• 60 panels × 9 kg = 540 kg
• Hardware (bumper, hangers): 30 kg
• Cables: 15 kg
• 20% margin: 117 kg
• **Total: 702 kg**

Weight Distribution

**For Ground Support:**

• Weight per square meter: kg/m²
• Base structure capacity
• Floor load limits

**For Flying:**

• Point loads at rigging connections
• Bridle angle effects
• Distributed vs. concentrated loads

Weight Impact on Design

**Rigging Capacity:**

• Truss rated capacity
• Motor selection
• Point load limits
• Safety factors

**Transport:**

• Truck weight limits
• Flight case packed weights
• Handling requirements
• Team size for load-in

**Installation:**

• Crew size needed
• Lift equipment requirements
• Assembly time
• Safety procedures

Specification Verification

**Always Verify:**

• Manufacturer published weight
• Actual weigh-in recommended
• Include all accessories
• Account for manufacturing variance

**Weight per Area:** Useful for comparison:

• kg per square meter
• Allows comparison across panel sizes
• Typical range: 25-50 kg/m²

Reducing Weight

**Panel Selection:**

• Magnesium vs. aluminum frames
• Carbon fiber options
• Thinner designs

**Configuration:**

• Smaller walls require less structure
• Ground support vs. flying trade-offs
• Segmented walls on separate structures

Safety Factors

**Industry Standards:**

• Ground support: 2:1 minimum
• Flying: 5:1 minimum
• Dynamic loads: 8:1 or higher

**Calculation:** Rated Capacity ≥ Total Weight × Safety Factor

**Example:**

• Wall weight: 700 kg
• Flying safety factor: 5
• Required rigging capacity: 3,500 kg
