Bumper (LED Rigging)
A bumper is a structural hardware component that attaches to the top of an LED wall stack to provide rigging points for flying. Bumpers distribute the load across multiple panels and connect to shackles, steel, or motors. Most LED manufacturers offer product-specific bumpers rated for the wall weight they support.
Understanding LED Bumpers
Bumpers are critical rigging components that safely transfer wall weight to flying systems. Understanding bumper specifications and proper use ensures safe flying.
Bumper Function
**Primary Purpose:**
- Provide rigging attachment points
- Distribute load across wall width
- Connect wall to flying system
- Transfer weight to truss/motors
**Secondary Functions:**
- Protect top panels
- Enable angle adjustment
- Facilitate assembly
Bumper Types
**Top Bumper:** Most common type:
- Attaches to top of wall
- Multiple pick points
- Main flying load
**Bottom Bumper:** For some configurations:
- Attaches to bottom
- Stability/angle control
- Secondary support
**Integrated:** Built into top panels:
- No separate piece
- Limited flexibility
- Cleaner appearance
Specifications
**Weight Rating:** Maximum load bumper can support:
- Published WLL (Working Load Limit)
- Apply safety factor (5:1)
- Include all panels below
**Pick Points:** Attachment locations:
- Number available
- Spacing options
- Load per point
**Compatibility:** Panel-specific:
- Manufacturer matched
- Quick-lock compatible
- Proper alignment
Installation
**Assembly:** 1. Verify bumper matches panel type 2. Connect to top row of panels 3. Engage all locks 4. Verify secure attachment
**Rigging Connection:** 1. Install shackles at pick points 2. Connect spansets/steel 3. Connect to motors 4. Verify all connections
Load Calculation
**Wall Weight:** Panel weight × panel count = base load
**Additional Loads:**
- Cables
- Bumper weight
- Any accessories
**Point Load:** Total ÷ number of pick points = load per point
**Safety Check:** Each point load < point rating ÷ 5
Common Configurations
**Two-Point Pick:**
- Simplest configuration
- Works for narrow walls
- Bridle to single motor option
**Three-Point Pick:**
- Better load distribution
- Center and ends
- Common for medium walls
**Four+ Point Pick:**
- Wide walls
- Heavy walls
- Even distribution
Safety Considerations
**Inspection:**
- Check bumper condition
- Verify ratings visible
- Look for damage/wear
- Test locks
**Documentation:**
- Record weights
- Document configuration
- Note any issues
**Certification:**
- Annual inspection recommended
- Weight testing
- Documentation maintenance
Compatibility Warning
**Not Universal:**
- Bumpers are product-specific
- Different panel = different bumper
- Never force fit
- Cross-brand incompatible
Frequently Asked Questions
How do I choose the right bumper for my LED wall?
Use the bumper designed for your specific LED panel product—bumpers are not universal. Verify the bumper is rated for the total weight of panels hanging below it, including any safety factor. Check that rigging point locations work with your truss or motor positions.
How many rigging points does a bumper need?
Minimum two points for stability. More points may be needed for wider walls or higher loads. Point spacing should distribute load evenly. Some bumpers have multiple attachment options for different configurations. Calculate point loads and verify each connection is within rated capacity.
Can I use a bumper to fly only part of a wall?
Bumpers are typically designed for the full width of panels. Flying partial widths may create unbalanced loads or exceed rated capacities at certain points. Consult manufacturer specifications for partial-width applications. Custom rigging solutions may be required.
